1 second of power?

Question: 1 second of power?

Heyall! Got a bit of a situation with my PC. About a month ago, I moved. After setting up the compy, I turned it on, and it seemed to only get a fraction of a second of power. I would push the power button for 10 sec to reset it, and when I pushed again, another >1 second burst. The fans would make half a revolution, and then nothing. I messed with it a bit, and after laying the compy on its side, it got power for ~5 sec. Rinse and repeat that for a while, and eventually it would get sustained power. There are 4 LED's on the mobo though, which seem to act as diagnostics. During the first boot of uninterrupted power, all 4 lights were red. Restart a few times and one or two would go green, a few more times, and they all went green, and the compy started running as though nothing was ever wrong. Well, I had to move again the other day, and my worst fear has happened upon me. It's back to getting a fraction of a second of power, and then nothing. No matter which way I turned it, or how I reset the machine, it refuses to stay up. I'm not sure what the heck is going on. Doesn't SEEM to be the power supply, because after last time, it went a month solid. No lock-ups, no unexplainable resets, just normal healthy PC activity. I suppose it COULD be a short, but I would've expected it to power down inexplicably in the past month, and I had moved it around slightly every here and there. Can't be a lack of wattage, as it wouldn't act like this, and I've never added anything to draw more power. I don't buy any of those ideas... Possibly faulty memory that inexplicably works 100% of the time it's "on"... Yes, the compy is old, so please refrain from dying of laughter as I list off the specs. MSI K7T Turbo SE MoboAthalon (one of the earliest gens) @ 800mHz (OC'd to ~1gHz)1.1GB PC133 RAM Please help, this is exceedingly annoying. (and yes, I intend to take the shotgun to it and make a big upgrade once tax time hits... PCI-E and DDR RAM, here I come... meantime I need this computer saved! :-/)

Preferred Solution: 1 second of power?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: 1 second of power?

Nothing wrong with an older machine. <-------------How about removing and reinstalling all of the add on cards, making sure all of the internal plug in connections are secure, reseating the RAM and making sure all fans are turning? Of course a good dusting would be helpful as well with a can of compressed air.What is the make and wattage of the power supply? You can look on the side of it while inside the case.

Hi, I hope someone can point me in the right direction with a problem I have with my Lenovo laptop.I have a T420s (Win 7 ultimate) that has stopped working. When connected to AC the battery light on the lid started blinking and stayed on but the battery was not charging, first thought was the known problems with the power manager and windows but when I changed the settings in the power manager it still didn't charge. When disconecting the battery the laptop was dead, it would only run with the battery connected but the strange thing is that it indicated that AC was connected but the system will not run on AC only? I've tried a second adapter (also 65w 20v) but that made no difference.Meanwhile the battery has run totaly empty. Leaving it unplugged for a few hours and then connecting it to AC power it gets power for 2 seconds and then dies again. Looks like a hardware problem? Any suggestions? Thanks for any help! Alex













Solved!

Go to Solution.

Answer:T420s no power on AC power but power management says AC power is connected?

Shot in the dark, but try the following.Unplug the battery, unplug the AC.Tap the power button ten times, then press and hold for 30 seconds.Reattach the AC and try booting it again.

Just faced a rather strange issue, but not really an issue, just different system behaviour than expected. System:W520 Batteries:55++ connected27++ connected Power adapter:Unplugged No other accessories connected. Scenario:I was using the system till it power itself off due to low power (0% reached for both batteries). i.e. Ungraceful Windows shutdown. Then upon pressing the power on button, the LEDs flashes, no THINKPAD logo or BIOS message appears, system appears to then restart again, and the LEDs flash again...and loops until it was no longer able to even attempt to POST. Expected behaviour:Either display the message that says "Battery level is too low".OrDon't loop (this is the behaviour when only the 55++ battery is connected at 0%) Why does having the 27++ would make the system go through this looping cycle?

Answer:W520, 55++, 27++, unplugged from power adapter, 0% battery. Press Power button --> power up loops.

Hello Chatbox,
 
I can understand your issue very well, as there is no message comes on the screen which gives you information to plug the power adapter and prevent the laptop to get shut down.
 
You should install Power Manager software and then customize it as per your requirement.
The software can be download from the mentioned below web link.
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8mu417ww.exe
 
 
Hope, after this laptop will not shut down automatically due to battery backup
 
Best Regards,
Tanuj

Welcome to the Lenovo Community !
 
Your problem could simply be a bad power button or there could be a more serious internal problem.  I would recommend that you contact Lenovo Support for service.

When plugging in the power adapter, the "charge" light does not come on, nor will the notebook power up. To rule out the HP power adapter I plugged in a Targus universal adapter (with correct polarity) and same result. Same results whether the battery is installed or not. The notebook had been in storage for several months, therefore, no recent changes. Any ideas?

Hi,
I have a recent DELL laptop:
Inspiron 7000 (Inspiron 17 7778 2-in-1),
Core i7, 16 Gb RAM, 128 GB SSD + 1TB HD...
Not a lot of programs and lots of space available.
In the last few months I have had a lot of poor performance issues. I finally figured out it is related to Windows 10 Power Plan. When set to "Power Saver", the performance is awful. The CPU is maxed to 0.80 GHz. So when browsing the net or looking at my picture gallery, the computer hangs, and it becomes impossible to use. If I change the plan to high performance, the computer behaves normally - fast!
And even if I change the plan to another plan (i.e. High Perf), the next time I restart or wake-up the computer, the "Power Saver" power plan is set back... Very frustrating. And as shows the image, it is not the "bolded" option in the list. What can be changing constantly that parameter??
I contacted DELL chat support and they asked me to re-install Windows! There is probably a better way to fix this. It looks to me as a DELL Driver conflicting with Windows. Also, my mother has an older DELL laptop on Windows 10 and she experiences the same issue...
Any help would be very appreciated!
Cheers,
Jean-Daniel

Hi, I have an Ideapad S400 that I bought a few months back. Recently it started having an issue. When I power it up, it wouldn't start. All the time, I could see the power LED solidly lit, but the screen is always blank/unpowered. a) Initially, it would start after about 30-40 minutes. b) When #a started happening, I thought that it was trying to bring up my session; Then I started shutting it down, and the problem in #a disappeared. c) After I started shutting it down occasionally, it would go to sleep when the lid is closed and then open up ok. However, if the battery drains overnight, I have the problem #a above.d) Later on, it wouldn't start at all. I had to take out the battery and the power cord, hold the power button for about 60 seconds, then put it. This would work one out of 10 times.  Each time, I can hear the hard disk click once after about 2 minutes after I power it up.   Now, I have been trying to switch it on and it wouldn't power up at all.  If the hdd or RAM failed, it would at least go show the POST screen. Here I am not able to see that the screen is being powered on.  I tried to connect it to a monitor via HDMI, but that didn't change anything.  Any idea what's going on.  Edit: OS: Windows 8.0 (I tried to update it to windows 8.1, but perhaps it couldn't boot it back, I got a message later saying that the OS couldn't be updated) Windows 8 question: What settings...

Answer:S400 doesn't power up (power LED is solid, but screen doesn't power up)

Subject line says it - unit runs fine, battery is is good shape, replaced charger with a new spare.  With PC on the docking station and all plugged in, both batt and power lights green, pushing either the laptop power button or the docking station power button, immediately extinguished both LED's and they remain that way until the laptop is removed from the docking station and the battery is removed and then reinserted into the laptop.  PC will then boot and run normally with battery showing full or nearly full charge.  Power cord can be reinstalled and all goes fine or the PC can be inserted onto the dock and all goes well also.  But, after a normal power down, the restart problem reoccurs, etc.... Any ideas out there? 

Answer:T60P w/Docking Station Battery & Power LED's Go out when Power button pushed rem batt to fix

OK - More Info: Removed it from the docking station and the problem persists, that is, once shutdown, restart will only occur if the battery is removed and then reinserted.  As a test, removed the battery and left it out, attached the power cord, and booted up successsfully.  Ran all day fine without the battery, then shut down without the battery, and next morning, without the battery, would not start.  AC Power light was on, but went out as soon as power button was pushed.  Removed power cord and reinserted it, still no start.  Put battery back in, started fine. So, with no battery, just AC cord, won't restart after a shutdown.  Also, with battery and AC cord, won't restart after a shutdown.  In both cases, however, if battery is installed, or if battery is removed momentarily and reinstalled, it boots up.

Toshiba Satellite L305-5955, Ive taken apart and replaced power jack. Not directly soldered to motherboard. While still apart, and battery out/in, connected power supply and still absolutely no response. Power supply is NOT original, and slightly different specs, i.e original 19v..6.3A

current 19v..3.1A
 

Answer:Toshiba Satellite L305-5955 does not respond to power supply, new power jack

Almost certainly the problem is that the current rating is wrong, if the laptop needs
6.3 A of current, it won't function on less (just as you can't use a 3A fuse for a kettle!)
Unfortunately it must be the right current rating, I know, I've been caught that way too!
Maybe you can exchange it?

My laptop is ThinkPad X1. Same situation. Originally was at 97% charge, once go to battery mode (AC unplug) battery immediately goes to 5% and then hibernate. Replaced 3 batteries from service center but problem still persist. Support Center keep insisting is battery problem despite 3 replacement batteries from service center! Lenovo is providing faulty batteries to customer for consecutively 3 times!? Issue has dragged for over 1 year and now Support Center says battery warranty is over and request to purchase new battery. If purchasing new battery can solve the issue, why did I need to replace the battery 3 times!? All batteries cycle counts range between 30 to 40 only. (Mostly on AC and recharge threshold is set to recharge at 33%). Lenovo batteries can only last for 3-6 months!? Despite case being escalated to "TOP MANAGEMENT", no response from Lenovo at all for over 1 week! Is this even escalating? Is this so-called "Customer Satisfaction" when satisfaction level is NEGATIVE ONE HUNDRED?

The original adapter cord for my T61 laptop shorted and sparked right at the base of the laptop connector where the cord had apparently cracked through from too much bending.  Then the laptop worked fine on the battery until it ran out of juice.  There is no indication of power to the laptop on the replacement power adapter cord though.  I verified power at the laptop end of the replacement cord with a multi meter. I think this pretty well isolates the problem to between where the cord plugs in and where the battery power joins the circuit, right?  Would that be in the power supply?  I've read that there is not a "power supply" per se in laptops but that it is integral with the fan kit.  So should I just be ordering a replacement "Thermal device and fan (Integrated)" to fix this problem?  I see in the part list that this is marked as "not to be replaced by the customer".  Is that just a warranty statement, irrelevant outside of warranty, or should I be looking for a good repair shop? I have some experience with computer repair, but have not dealt with any repair shops in years, and have never dug into a laptop myself.  What I think I know to this point, as stated above, is based on a bit of web searching and general experience.  In reality, I'm very unsure of anything I've said regarding diagnosis or next steps.  Please advise. Thank you, James

Hi Anish1,
 
Welcome to the Forums  
 
As per the query we understood that you are facing issue with black screen in your Lenovo G510 laptop.
 
As you have mentioned that black screen when turned on, can you hear the windows login sound?
Remove the battery and connect only adapter and check for the issue also connect only battery and check for the issue.
 
Connect an external monitor and check if the display appears in the external monitor then its a issue with the LCD, if there is no display in the external monitor then it might be issue with the motherboard, hence suggest you to visit the nearest authorised service centre.
 
Click here for the service centre and select your region.

Hello all, I recently recieved my IdeaPad Y410p from the Lenovo repair centre and they changed my system board for a different issue, but now I have a new problem. I updated Windows to 8.1 and did all the critical updates and then tried to uninstall some of Lenovo's bloatware and now my laptop won't turn on or charge the battery. I tried to do a power drain (remove the battery and hold down the power button), but still no luck. The laptop won't turn on at all with the battery or the plug by itself.  I then waited a few hours and tried to turn on my laptop again and then this time it powered on for some reason! I quickly restored my system back to Windows 8 thinking there was a problem with an update or bloatware uninstallation and then all seemed well until  I powered down my laptop again, but then couldn't power it back on. I called Leneovo and they said it was impossible for it to be a hardware problem since they just repaired it and since I updated everything and then restored it back, which then it still had the same power issues means it most likely isn't software. The only other thing I could think of is there might be a problem with the power adapter, but I've had this laptop since July 2013 and the adapter was working perfectly fine and this problem only started once I received my laptop back from Lenovo after a "repair". Any other suggestions would be very much appreciated at this point. Thanks!

Answer:Lenovo IdeaPad Y410p won't power on with power adapter plugged in and won't charge battery.

Hi there -  I wanted to add that I am having the same problem. I sent my Lenovo in for warranty repair (rear left hinge broke) - I got it back Friday May 16th and ever since then it won't stay on and sometimes won't turn on. I called Lenovo warranty support and (of course) they denied it was their problem. However, I complained enough that they're going to send me a new one. Of course, you have to be in-warranty for this to work. Just a suggestion Hope you get your straightened out!!!

Just disassembled my Z580 to check why it wasn't starting up (another thread) as I figured if I'm going to have to get a independent engineers report I might as well open it myself at the same time. Followed all the steps as outlined in the hardware maintenance manual and found no sign of any hardware damage/power surge/blowouts anywhere. I then reassembled the laptop using the same guide (with no extra screws) and placed the battery in (just to confirm I took out the motherboard battery once I could and reinserted it when I was closing up). Much to my confusion and relief that there is some sign of life, the power button, power light, battery light and caps lock light are flashing in that order. A couple of times when I press the power button the touch sensitive volume buttons also flashed, but that's only when I press the power button sometimes. I can't find any info on these lights online. Any quick help would be appreciated

Hello,
After putting my computer into sleep mode last night, I was unable to get it to boot into windows this morning. When i pressed the power buttong, everything turn on and working (all fans are functional, gpu power led is on, all hard drives & cd drives are functional.

The only way to turn it off is by pulling the power supply cord or turning the power supply switch off.

Answer:Windows 7 blank screen after sleep mode (unable to power off with power button)

Hello,

Is it possible that you can test with another compatible PSU? I would strongly suggest doing so.

Also try the following steps:
?Make sure that the (internal) speaker is connected to the motherboard
?Remove all memory and attempt to boot the PC
?You should get the no memory beep errors

If the Power Supply is in working order and no beeps are present then it can be indicative of a faulty motherboard.

For troubleshooting purposes it may be a good idea to remove the components from the case and bench test to rule out a short.

Answer:Inspiron 17R won't start. Only the first light turns on and of when I power up without the battery and Plugged power.

Unplug the system, remove or disconnect the battery, and hold the power button for 30 sec.  Remove the base cover and memory modules;  reinstall both.
Try powering up on AC only - if it will but won't with the battery, the battery is faulty.
If it still won't power up  after the foregoing, the mainboard is bad.

I run a 2004 HP Pavillion XP with an AMD 2.08 & ddr 2700. It has 64mb integrated video & an AGP4X/8X slot; A7V8X-LA, VIA VT8378,  UNIVERSAL 1.5v AGP 3.0 MBO. 1.To convert to a 128 or 256 mb video card, will the cards require an external power attachment, such as from my spare floppy connector? 2. Will the BIOS handle an AGP 6200 card? 3. To update my 250w ATX12V power supply, what happens if the new psu has a manual on-off switch? My current unit has a remote front panel interrupt-type power switch. 4. My mbo handles SATA I. If I use a new PSU with SATA, will SATA II devices have built-in jumpers to convert back to SATA I?  5. The mbo supports a 3200+ processor, will DDR 3200, 400 mhz memory work with the current 2700+ 333 mhz processor; is this called overclocking?

Answer:AGP Video Card Power & ATX12V Power Supply Manual Switches

Okay, hopefully I don't miss anything, that's quite a list 1. Video cards don't connect to the power supply, they draw the power through the mother board.2. The AGP 6200 should work just fine, just remember to disable the integrated video in the bios.3. The switches on the power supplies are just a master on/off, the power button on the front of the computer isconnected to your mother board.  Don't worry about that one.4. Why not pick up a SATA II controller?  Treat yourself 5. No, it's not overclocking, I actually wouldn't recommend overclocking at all.  Whether or not your motherboard will actually work with the DDR 3200 that should be in your motherboard manual, or if you want me to look that up for you post your make and model of motherboard.  A good rule of thumb is to only get the type of RAM that is already installed.  I'm referring to the speed and type, not the size.I hope this helps, if you have any other questions don't hesitate to ask.

Hello All:

I have a HP DV6275US, Pavillion DV6000 with Vista Home Premium on it and I am trying to go to XP. Dual booting is too much of a ruckus and I do not like it anyways, so I bought a Scorpio to install it on.

When I installed the Scorpio, it initially would not detect the drive, so I disabled SATA Auto. in the BIOS, and it then recognized it.

So, I start to install XP, formatted fine, copied sys. files fine, but when I got to the actual GUI install it asked me if I wanted to install a driver for my battery, which could possibly disrupt installation, so I choose yes and anyways and it proceeded fine for about a minute, then power failure. Tried again, and again, and same thing.

I put my Vista HDD back in, a Seagate 160GB, and things worked fine.

I have read something about having to manually load the drivers for the nVidia RAID chipset, as the ones XP Install loads do not suffice. I could not find any problems about the battery, so please, ANY help would be greatly appreciated.

Thanks a lot.

My Dell Inspiron 1545 has been sitting for a while, and when I went to plug it it and try to use it, it would not turn on. All I got is a pulsing power light like when it's in sleep.
I recently replaced the battery as well as the charger, because the original battery was shot and the charger was in horrible shape. I also replaced the power jack a while back because the pins inside were bent and the laptop got no power.
I had successfully used the laptop for a while after replacing these parts, but now it won't turn on. Whether I'm on battery, AC power, or both, it only flashes/pulses when I press the power button. If I hold the power button, it will shut off.
What's wrong here? I have checked and re-seated both memory modules, also testing both slots and nothing changed.

Answer:Inspiron 1545 Won't Power On, Pulsing Power Light Like When In Sleep Mode

Hi CARCRAZY98,
Thank you for the update.
Well, when you power on the system, if you hear the fan spinning and the HDD turning on, connect an external monitor and check if there is any display.
Reseat the cmos battery and check when possible. Since the system draws power from the adapter, at this point, I would not suspect the adapter. Also, remove the memory modules and disconnect the HDD and check if the system comes on and beeps - indicating a missing HDD / memory.
As advised in my previous post, if nothing works and the indications do not change, I would suspect the motherboard.
Let us know if you have any other queries.

I'm interested in the Toshiba G25 laptop but have heard that you can't use it on airplane seat power. It comes with a 120W AC power supply (15Vx8A), but I've been told that most airlines limit seat power to 75-90W max. Lind sells a 12V car adaptor for the G25, but specifically won't include an airline plug for this reason (which I can get independently, of course). I've read some interesting electrical discussions on this board. Can ya'll comment on the following or provide any general advice about power consumption?

1) Given that the voltage of the laptop and airline seat power pretty much match up (12-15V), if the amp draw on the laptop exceeds what the airline power supply can deliver, what will happen? Will it damage the laptop to feed it insufficient current? Will it shut down the laptop altogether? Merely dim the screen?

2) If I remove the laptop battery, which requires power to charge it, how much will that reduce the power need of the laptop? I'm not sure how to work the math, but the spec sheet states the battery supplies 4400mAh at 8A output. Does it require the same to charge it?

3) Most importantly, on my 15 hour transpacific flights, will the DVD player work with that ultrabrite screen at the low airline power supply? A nice feature of the laptop is that you can watch DVDs without powering up the Windows operating system (it has a small linux OS for the DVD player). Granted, the DVD drive and screen are prob...

Why does shutting down the computer, removing the AC Adapter, removing the battery (if it is a laptop), and holding down the power button for 30 seconds fix problems in one's computer. I was recently corrected in a post of mine that this does not actually do anything unless one removes the 3 volt battery from the motherboard, but I know this is not true from experience. Here is the correction I am referring to from a more experienced member:

You can reset the BIOS defaults by selecting that option from within the BIOS settings. Usually on the Exit menu.

To reset the CMOS (Clear the CMOS chip) there will be either a jumper on the motherboard to perform this function with, or newer boards have an actual reset button.

The above procedure will work to restore the BIOS defaults if you add the step:

Hello As much as I can see, many of my ThinkPad w530 stock Power Manager options are the same as in Windows 7 power options (power plans). But I was not able to find anywhere an answer to my quite obvious question, which of them settings have a priority in the event, that they are different? Say, if I choose "Enter system standby" value "after 30 min of idle" in ThinkPad Power Manager, but set the value of the same option to "Never" or "5 minutes" in Windows power options, which should work? Or may be the both simultaneously?  Thanks! P.S.Certainly I can check it myself which a series of simple tests, how it actually works. But my question has a bit another point, that is how these things should work. (I have some minor issues, say, laptop does not go to sleep/standby when works on AC, although previously it did it exactly as it is configured in Power Manager idle settings. So in order to detect possible cause I whish to understand, how it should work.)

Answer:Windows Power Management - Power Saver - is this safe for graphic card

Power Saver attempts to save power by reducing the CPU’s speed all the time and lowering screen brightness, among other similar settings and that may account for your fps drop when benchmarking. Doesn't sound like a good choice for your purposes.

Hello, I have a T530 quad core, which means I need the 135W power adapter.  I was flying yesterday and my seat had power, so I figured I would use the "Airplane In-Seat Power Mode" function on Power Manager to avoid tripping any breakers on the airplane.  However (and I've tried this at home as well on AC mains), choosing the airplane in-seat power mode doesn't seem to result in the advertised "adjusting charge rate and cpu" - instead it just causes the laptop to not charge at all and say this: "This AC adapter may not provide enough power to your Lenovo computer. Please reconnect the proper AC adapter." Of course... it is the right adapter... and switching off Airplane Power Mode makes it start charging normally again immediately. I have the BIOS update needed that says it enables this feature (1.12), and Power Manager 6.32. Has anyone else tried Airplane In-Seat Power Mode and had it work, or can anyone from Lenovo comment on this? THANKS!

I have a Dell Dimension E510 that as of yesterday, won't power up anymore. The power light blinks orange and the computer does nothing when the power button is pushed or held in. It's about 16 months old and is out of warranty, so I'm trying to diagnose the problem myself.

I did some searching on the internet and found that this seems to be a common issue on these Dells, sort of a long term infant mortality issue. The most common causes seem to be a bad PSU, MOBO or a shorted USB input.

I've done some diagnostic checks/testing so far and am now stuck. Here's what I know.

- The USB ports don't appear to be shorted. I also disconnected the connector for the USB (which includes the power switch :banghead and it doesn't change any of the results that follow.
- I removed the power supply and jumped Power On (terminal 14, green wire) of the main ATX connector to ground. The fan comes on and all voltages (3.3, 5 and 12v)check out, including around 5.35v at Power Good (terminal 8, gray wire).
- With the power supply back in and everything connected, there is only 3.3mv at Power Good. As I understand it, this would normaly point to a bad power supply; however, all of the voltages check out when the unit is disconnected from everything.

Is is still possible that the power supply is bad, or is it more likely (or definitely) that the MOBO is the culprit.

Any help, including suggestions for additional testing is greatly appreciated.

Hoping someone here can offer some advice? I own a Dell studio xps 435t-9000 that is a couple years old.

After I installed it, the first time my computer went into sleep mode/hibernation I couldn't wake it up. Power light was flashing white. Eventually I shut it down manually and then it wouldn't boot. Had a solid amber light, no power except the power supply. Fans not working. I unplugged everything and made sure it was all good. Wouldn't start. Left it overnight and plugged it in the next morning. Started up. Worked great for about 7 hours and then just randomly shut down, no errors or anything. Same deal. Wouldn't start, amber solid power light. Let it sit for awhile, reseated everything and wouldn't start.Gave up for awhile, tried a few hours later and it started. I read a few boards pointing to the power supply being bad or not powerful enough. However, I replaced the power supply about 6 months ago with a Corsair 600 which is plenty power. Could still be an issue perhaps but seems odd it would die in that little time. I also replaced my graphics card if that matters.

Two weeks ago my PC randomly started suffering from shutdowns where it was immediately lose power, and then I restarted it... it would cycle on and off every few seconds until I physically removed the power plug from the motherboard and reinserted it.

First I thought it was the PSU, which is a 1000w Mach, and I replaced it with a smaller 600w and still the issue persisted. There was no smoke or any other visible cue which would lead me to suspect that it was a PSU problem.

Then I thought it was the CPU. I have a Q6600 with a Zalman heatsink. I downloaded speed fan and the temperatures were fine, I never saw them go above 55-65c.

Then I thought it was the motherboard. I bought a brand new EP45 and rebuilt my computer, installed my CPU and installed my heatsink, cleaned off all the dust, new case. etc.

When I went to install the operating system, it started happening again...

Then I tried doing it with different sticks of ram, and still... it persists. The only thing I haven't checked is the video card, but that wouldn't cause a system malfunction or a power cycling problem.

Something is overheating and I don't know what it is.

Hello!

My Toshiba Satellite P755-S5265 has not been able to turn on at all. That's because the AC adapter would not be charging the battery nor would it operate the computer.

Whenever I would plug in my adapter, a weird clicking noise would come out from the computer. Also, the AC adapter charging light would blink continuously as well. I

took apart my laptop and discovered that the end my of DC power jack was the source of the clicking. When I mean the end, I don't mean the area where I plug in my adapter, it's the other end that's connected to the motherboard.

Does anybody have any advice on what I should do? Is my laptop dead and done for?

ATI Radeon 4870

The problem is that the motherboard will NOT power up at all with the 2 of the latest power supplies (600 watt+) i have.

It wont work at all with; (Nothing happens its just dead)
Arctic 600 watt Jeantech PSU (brand new and working)
Corsair 620 watt HX PSU (working)


It only seems to work with my Jeantech 450 Watt PSU and i cant for the life of me figure out why. Ive tried everything to get the board to work with the new PSU's. I had thought that the PSUs i got were dodgy but after testing out one in an older PC it worked fine.

Ive removed all parts and tried powering up and i cant get it to boot up. But the PC seems to work fine with the oldish 450 watt PSU which i find just unbelievable.

Can anyone help with this nightmare? Now on the Gigabyte site the CPU i have isnt listed as supported by this motherboard which is kinda worrying could this be the reason? If so how the old PSU boots up.

I just want to have the fracking thing working with the right PSU.
 

Answer:Power Supply Wont Power up - Gigabyte ga-ma790fx & AMD Phenom 9850

if I read the specifications right on your mobo... it implies that it has the 4 pin PCI-e input(power) but it also has the 8pin ATX power conector. (it may be simply removing a cap that is actually right next to the 4 pin connector, thus making it an 8 pin connector (thats how it was on my mobo)

Try using the 8pin power with your new PSU, see if that works.

Hi,
I picked up this Alienware 5700 off ebay to hopefully refurbish for my son but I'm new at this and still learning and so this thing has me baffled. The laptop is in pristine condition but shows no signs of life. When I plug in the power supply the green light on the power supply goes from solid green to blinking rapidly to the point you can barely see it. To me that would mean a short somewhere right ? If so where ? Has anyone else ever had experience with something like this ? I just don't want to go buying a new battery for a laptop that maybe fried already. Any help would be greatly appreciated.
 

Answer:No power, no lights but green light on power supply blinks rapidly

Remove the laptops battery and try the AC power only. If the green light does the same, it still could only be a bad AC adapter, or at worst, a shorted laptop motherboard

So my N21 chromebook seems to have a AC connector issue, most likely on the chromebook itself. as seen in the photo and video, the connector seems very loose, and no light comes on when plugged. it doesnt "click" when plugging in like other laptops, it just "slides" in and slides out very easily https://goo.gl/photos/5jujCxawE3AubxvP7 i tested the AC power adapter (official) with a multimeter while it is plugged into outlet, and it shows 20V which means it SHOULD work ok.  but obviously does not when plugged in, I feel it's very loose and when i looked into replacement AC adapters there seems to be TWO different connector sizes:  http://www.ebay.com/itm/Original-OEM-Lenovo-Chromebook-N21-45W-20V-2-25A-3mm-AC-Adapter-ADLX45DLC3A-...  <-- 3mm X 1mm http://www.ebay.com/itm/Lenovo-Chromebook-N21-Notebook-20V-2-25A-45W-Power-AC-Adapter-Charger-Cable-... <--- 4mm x 1.7mm What I have is the 3mm X 1mm , and i'm thinking it might be NOT charging because it is too loose and not touching. So will buying the 4mm X 1.7mm work as it is "tighter"?  But why is the official one loose?

Answer:Chromebook N21 Power AC Connector , not charging / no power light, loose? Replacement size confusion

I would presume that the power adapter that came with your Chromeboosk is the correct one, which should be part number 5A10H70353 (see link below).      If it was working fine before and just started acting up, it is probably a problem with the jack itself, and not the size of the power plug.     If it is under warranty it would be covered, but if not under warranty, the part needed to fix it is part number 5C10H70350  $12.95 USD and is available from the link below.    If the system is not under warranty, instructions on how to replace the DC-in cable begin on the bottom of page 35 in the Lenovo Cromebook N21 Hardware Maintenance Manual and requires some disassembling of your Chromebootk, but if not comfortable in doing it yourself, it should only take a good laptop tech about an hour to replace. Note:   Before buying an parts, I would recommend that you go to http://pcsupport.lenovo.com, click on the Detect My Serial Number, and then click on the Parts & Accessories link to ensure that the parts you purchase match the exact Machine Type-Model or Machine Type of your system..    5C10H70350 Lenovo Ct Cables Internalhttps://lenovo.encompass.com/item/10633467/Lenovo/5C10H70350/Ct_Cables_Internal 5A10H70353 Lenovo Ad Ac Adaptershttps://lenovo.encompass.com/item/10638409/Lenovo/5A10H70353/Ad_Ac_Adapters Hardware Maintenance Manual Le...

I bought a refurbished T400 less than 3 months ago. Today the power status change beeps started going off every minute or so, the power indicator light went off (while plugged in) and the battery began discharging. At the same time, the screen started flickering. I powered down and tried draining the static by using the old trick: removing the battery and ac plug and pressing the start button 10 times and then holding on the 11th try. Didn't solve the problem. When I use battery only, the screen doesn't flicker. Plug in power and the screen starts flickering again, with the power LED mostly off but occasionally flickering on briefly.The battery is not listed as charging. Nothing to indicate that the power is plugged in, except for the occasional flash of the LED and the power status change beeps. When I power down again and stay plugged in both the power LED and the battery LED keep flashing. First both are flashing green, but in a few minutes the battery light turns flashing orange. If I remove the battery, both LEDs keep flashing. Try to power on that way and nothing happens - the LED's keep flashing, but it doesn't power on at all Battery is new (the first one shipped wouldn't hold a charge at all; this one lists as good condition). I don't have another Lenovo power supply to try, but the current one doesn't appear damaged or bent at all. I tried jiggling it while plugged in and there was no change. The last thing I did before the pr... Read more

Answer:T400 Power Problem: Flashing AC Power LED, No Battery Charge, Screen Flicker, No AC Boot

It sounds like either the ac adapter is sick (most likely) or the jack is bad.  If the power supply doesn't have "Lenovo" moulded into the plastic, it is probably a knock-off, and they use crummy wires between the transformer and the round plug.  This is a common probem for fake adapters

Try the following...

1. Take out (or take it off) the charger.
2. Next take out the battery
3. Now hold down power button for 20 seconds and then rinsert battery.
4. Now put it on the charger again

NOTE: Make sure charger is plugged into the main power supply (not an extension cord, surge protector, etc.)

Sometimes, when the device is not plugged in directly, it doesn't get the power it needs. Holding the power button, while you restart it, clears out the temporary ram (no it won't delete anything you have saved) and will give the device access to the ram it needs.

I want to share my experience with setting idle timers under Lenovo Power Manager or Windows Power Options, respectively. I noticed that every time the monitor just had dimmed or shut off according to my power savings options, it brightened up or turned on again only a few seconds later. I had seen the same behavior before using my Dell Latitude laptop, so I came up with the solution relatively quickly this time. The interference was caused by a Logitech wireless mouse, even though all drivers were installed correctly and the mouse was working flawlessly. Installing the Logitech SetPoint firmware solved the problem in both cases without further steps being necessary. Maybe this note will help other users facing the same issue. Good luck.

You could check in the BIOS if the option called USB Sleep & Charge was enabled or disabled.

Change this setting and save up the changes. Then boot again.

I replaced the DC jack on an Acer today with a new one. When the laptop has the battery in the power LED shows a power source(unfortunately the battery is dead). When I remove the battery and plug in the charger to the new DC jack, no LED. Hitting the power button results in a flash from the power button light and power LED for an instant but no POST or boot. I tried different chargers as I have a few universals laying around so that's not it.....What's the problem?

I have a Lenovo T410 which has been exhibiting keyboard issues (several keys have failed and I've been using an external keyboard). It seems that the keyboard failure is affecting the powering up of the machine. Occasionally it will turn on, most of the time it will not. I've submitted an eService request for this and the status is "Solution Provided" but the "SO Status (as shown on ICSS)" is "On Hold" "Order on hold, pending update" (per: http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?DocID=HT074324 ). This has been the case since the 28th of last month. I've confirmed it is a keyboard failure by swapping a keyboard from a T420 (which, ironically, had a service request fulfilled fine around the same time). I have two questions: i) most urgently, is there *any* way I can power the machine on without using the keyboard?ii) what do I do about the service request's "On Hold" status? this machine is out of action and key to our work.  

Answer:Lenovo T410 does not power on due to keyboard / power button issue.

i) There are three ways to power on the laptop without the power button. a) Use a dock. b) Check under BIOS menu (if possible) under power, to see whether you have something called 'Power On with AC Attach' feature. If you do enable it, and save then exit. What this do, is that it will power on the laptop when you connect the power plug into the laptop. http://www.flickr.com/photos/lead_org/8991415709/c) remove the CMOS battery, and power on the laptop by attaching the power adapter to the laptop.

The tips I got with this Kensington 33197 power adapter have numbers stenciled on them like N3, N5, N19, etc. The tips sold on their web site make no mention of the "N" numbers and have numbers like K20059, K20050, etc. and there is no cross reference.

You can also see a complete reference for "N" numbers to all the laptops they support at the above link. Again, no mention of the numbers Kensington uses on their site.

hey

My Equium A60-692 has stopped receiving any power from the AC adaptor (tho I've metered it and its giving out a good 19v). I've noticed the end of the adaptor (the end that goes into the laptop) is different to normal ones. Rather than having a hole at the center that a spike on the laptop fits into, its just got a flat piece of metal. Just wondered this was normal and the problem is inside the laptop or if the spike has somehow snapped off and is stuck into the adaptor. It looks like its supposed to be this way but it seems a bit weird...

cheers

Answer:Equium A60-692 Power supply - laptop doesn't receive any power

HI Rodders,

Bad news I'm afraid. The flat piece of metal that you describe is the back end of the central pin that has snapped off the inside of the power socket on your notebook. This is quite a common occurrence (check out some of the other posts on these forums).

Unfortunately the solution to this problem is for your nearest Authorised Service Partner to replace the mainboard (quite expensive!) unless you can find someone willing to solder in a new power socket.

Very sorry to be the bearer of such bad tidings.

regards,

First time I have ever seen that feature. I like it. I'm thinking that is a neat/easy way to partially eliminate cable clutter from the PSU. Give it a shot, you can always revert to PSU cable if you wish.

I have a Sony VGC-RB42G computer. I recently moved my computer, cleaned off all the dust, and when I plugged everything back in, it won't power up. The light on the power supply blinks green, inside the motherboard also has a green light that blinks as well. It has a ticking sound too, but I am not sure if it is coming from the power supply or the motherboard. Any idea what could be wrong.

FYI, I have already unplugged everything from the power supply, pulled out the ram, checked the battery, and put everything back together and still no change. One thing I thought was strange was after I unplugged everything, I pulled the power into the power supply again and this time the green light came on but did not blink. It stayed solid.

I was looking at an SSDrive, specifically a Kingston 60GB, for a laptop, but older posts on SSD say they consume more power than standard platter type HD's. Anyone know of a SSD that is more or less equal in power consumption than a standard platter drive?
 

Answer:SSD vs Standard HD in Laptop-Battery power, any equal in power consumption?

I'd not go with less than 120 GB with a SSD. 60 GB is not enough at all.

Overall, I'd say that SSD's are worth it, when it comes to speed. That laptop will feel like "The Flash" compared to the slow 5400 rpm drive that most laptops are using.
