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

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

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?

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 (This link will automatically start a download of Reimage that you can save to your computer.)

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.

Hope, after this laptop will not shut down automatically due to battery backup

Best Regards,

recently bought a Dell Inspiron 14 5459 on June 12, 2016 and first thing I noticed is that to turn on the laptop I need to press and hold down the power button at least for 3 seconds in order for the laptop to boot up, this seems strange, I brought up this issue at the Dell Store where I bought the laptop and the sales people there told me that they noticed this in most Inspiron models.  Is this normal?

Answer:Dell Inspiron 14 5459 power button needs 3 seconds long press to power up?

Thank you for writing to us!
This is unusual we would suggest you to check with another system to see if the same happens.
Kindly provide us with the service tag and email address.

Hi, so I have had a powering issue with my previous power supply which was the Corsair CX600W so i purchased a newer power supply - the EVGA SuperNova G2 550W. I unhooked my old psu, hooked up my new one and the PC turned on and I turned it back off from the power button on the case. I also hava a boot drive problem so I unplugged the sata cables from my SSD and wanted to try to turn on the PC with only my HDD. I did this with the PSU switched off and the power cord unplugged. When I tried turning the PC on again the PSU made a clicking noise and nothing turns on. The motherboard Led's are lit up so it is definitely getting power but when I go to turn the computer on it just makes a quick clicking noise and nothing turns on. Any help is appreciated, thanks!

I have a Nokia lumia 900, and when you hold (or press twice I believe) it shows the thing to turn it off, right? Well when I press it one time quickly it does it..? I can't lock it unless I let it lock by itself.... Is there a fix?

Answer:I press the power button one time and it says slide to turn power off?

What  will happen if I remove the battery of a laptop and press the power button for 30 seconds??
Can anyone explain me in detail please!

Answer:What will happen if I remove the battery of a laptop and press the power button for 30 seconds??

It is a system reset - it resets the firmware to factory defaults.  If something is stored in CMOS that's preventing a boot, it will clear that -- it's a last ditch effort to confirm the fault lies elsewhere (usually with the mainboard).

My laptop will no longer turn on.  When the AC adapter is plugged in, the LED light is white indicating power is arriving at the laptop. However, nothing happens when I push the power button. Troubleshooting steps I have completed already include: Hard reset (several times including after each step below)Tried starting without the batteryRemoved all removable components and reseated themRemoved all removable components as well as bottom cover. Cleaned with compressed air. Put everything back.Nothing appears wrong and nothing happened between the last time it turned on and this time that I am aware of. The laptop is out of warranty, and I am pretty handy with computers. Is there anything that can be suggested short of a hardware replacement that would help get this resolved? TIA

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

Answer:Z580 power, battery, caps lock and power button blinking in order

Just a quick edit: By some miracle it has powered up and all seems well. Only oddity is that some icons in the bottom taskbar are invisible, but fan and everything else seems to be working fine with no issues in device manager.

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.

Answer:Power loss failure (immediate reset) whenever switching from power adapter to battery (unplug)

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?

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!!!

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

I wasn't exactly sure which subforum this post would belong in, and I know this isn't exactly a troubleshooting forum but I need help.

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.

Answer:Computer losing power, failing to power itself back on until unplugged/replugged.

try a different power outlet?
plug straight into the outlet if you're currently plugged into a powerstrip or surge protector?

When I press the self test button several times, once in a while I see lights and fans working. I tried Memok on motherboard and no joy. One thing I did notice was when I remove the 4 pin CPU cable from PSU, the self test works instantly but the power button still doesnt work. Nothing, also did jumper on power l, reset CMOS. Could this be my CpU fried? Or the motherboard? I still need to take it out from case and check for capacitors etc..

Ok so here's the situation :

my friend's PC suddenly stopped working something like a month ago. He took it to some local computer repair shop who diagnosed a dead mobo and PSU.

They told him his mobo was now impossible to find and since I could get my hands on one fairly easily he asked me to repair it for him.

So basicly I changed his PSU and ordered a new INTEL D865GLC Socket 478 (his mobo)... I just received the damn thing and even with the brand new mobo the PC does the exact same **** :

I press the power button and absolutely nothing happens, nothing! Even the fans stay idle . What could be the cause? I even tried shorting the POWER SW pins with a screwdriver to make sure it wasn't the case Power Button but in vain.

I tried swapping mem sticks, changing PSU, tried removing HDD, DVD drive and GPU... no help there either.

Could it be a dead CPU?

Hi every one,
Recently I purchased new PC,
After installing windows XP Pro SP3 I found that there is a missing button in Power option properties. The missing button is (When I press the sleep button on my computer), I can find only (When I press the power button on my computer).
My system configuration is as follow
Mother board Gigabyte EP45-UD3R Rev 1.1
My graphic card is ATI Radeon HD 5670
Windows XP SP3
RAM 4Gb Kingston DDRII
CPU Core 2 Quad 2.66 GHz
It worth saying that I can shutdown, hibernate or put my PC into sleep mode, so the functions are working but only the button is missing.
I will appreciated very much if some can advise me how to restore the missing button. Is there some option in BIOS that will enable this button?
I contacted Gigabyte customer support, but they directed me to Microsoft, I also contacted ATI but they directed me to Microsoft or BIOS settings. In my BIOS I can't find any option that may affect this button. Any advise will be appreciated
Best regards

Answer:[SOLVED] Button of (When I press sleep button) is not available in my Power option pr

Does the case actually have a separate Sleep Button? I suspect it's not even connected, as the motherboard manual doesn't show a connection for a Sleep Button, only a Power Button.
Windows Power Options won't list it, as it doesn't exist.

If you have a Sleep Button on the keyboard, it might not be listed in Power Options either. That would be up to the Driver software to add that option. You may have to use the software that came with the keyboard to configure the sleep button on the keyboard.

Hi guys, I have to press the power button twice on my X60 to boot up after leaving the laptop off for a couple of hours. The first press, the "Z" light & "Battery" light will stay on and nothing will happened.

I set my Dell Inspiron laptop (Windows 8) to sleep after 15 minutes (never to hibernate) whether on AC power or battery.
This allows me to take out my laptop from my bag, open the lid, enter my pin and get to work quickly.
One thing that baffles me is that when on AC power, I have to press the power button to "wake" the laptop out of sleep
instead of just pressing a key on the keyboard. The power button is this tiny chicklet metal button that is awkward to press.
Any way to set Windows 8 to wake on keypress when on AC power?

You do not find it in Power Options to change power button from doing it? Only know ways if using an external USB device. Should be a sleep button or one of the F buttons or Fn.

I have an XPS13 that I wanted to get a spare power adapter for.  I purchased a used genuine Dell JT9DM on eBay.  Same model number as the original adapter.  If I plug the new adapter into the laptop and into the wall it charges the laptop.  If I remove the power connector from the laptop the green light on the power adapter goes out and will not turn back on unless you unplug it from the wall and then plug it back in.  The power adapter that came with the laptop does not do this, the green light stays on regardless of being connected to the laptop.
I figured the adapter I got on eBay was defective and purchased another.  It does the exact same thing.  So while I can charge the laptop battery with the two adapters, I have to unplug them from the wall every time I connect the adapter back into the laptop.  Is there some way to re-program the adapter to stay on all the time?

Title says it all really. I haven't been able to shutdown my PC for a few months now without holding down the power button for a few seconds. I used to just leave my PC in sleep mode but, when this first started, it would often turn itself off instead of sleeping or enter sleep mode instead of turning off. It's not a major issue, granted, but it is still an annoyance that I would rather have fixed. If aynone knows the steps to attempt to remedy this I would be very grateful!

Answer:laptop not responding for sometime after i press power button

That's very difficult to diagnose without seeing the laptop. It could be a hardware or software issue. Is it under warranty?

If the lid on my computer is closed for a couple of hours or more, opening the lid DOES NOT bring the computer out of sleep mode. I'm assuming that it's in sleep as it wakes almost instantly but simply opening the lid should do that. If the lid has only been closed for a few minutes, it will start up if you open the lid. I have another UltraBook running Windows 10 and you can raise the lid after a couple of days and the computer will come to life but on my new x360 I have to press the power button? Power is set to sleep when the lid is closed.

My hp G62-144DX can't boot when I try to start with the power button. No lights bling anywhere within the laptop. When I plus in the AC adapter to the charging port, it lights up the white led, then turns to orange as a sign that it's charging.I tried to soft reset by removing the battery and unplugged other peripherals then long pressed the power button for about 30 seconds, plugged in the ac adapter then tried to boot my pc. All this never worked.Sometimes back, the laptop had the same problemonce or twice, and it starts working after some while like a day or two. I never knew what exactly the problem was. This time round, it can't boot yet for three days now and I can't figure out what the problem is.

Hi there, I bought my Lenovo Y40 on the Lenovo Web site a couple months ago and recently, to turn on, I have to press the power button twice. When I press just once, the Lenovo`s logo is displayed on the screen, but after 2 seconds everything turns off. On the second trying, finally the laptop turns on and the windows is started.In addition, rarely the laptop stucks on the lenovo`s logo screen, being necessary to hold on the power to reset it. Has anyone had some problem like these describe above? Thank you.Pedro Lopes.

Answer:Lenovo Y40: Needs to press the power button twice to turn on

Welcome to the Lenovo Community Pedro !
Try doing what I call a soft reset of the BIOS. This can be useful in some situations to resolve hardware conflicts Here's how......1. Unplug the charger / adapter 2. Remove the battery. 3. Press and hold the Power Button for 15 seconds. 4. Re-install the battery, plug in the charger / adapter if needed and power up the system to see if the problem was resolved.
If that didn't resolve the problem then I suggest you contact Lenovo Support for warranty service.  From what you have described there is a hardware problem with the laptop that needs fixing. You can find the phone number for Lenovo Support in your country or area by using the link below....

My aunt got a lap top, can't remember the name of it. It's running win7 64-bit.
When you press the power button, instead of turning off, it just goes into standby.

Answer:Lapt top goes in standby when you press power button

RB_Kandy,The function of the power button can be changed in Power Options.Start (orb) ->Control Panel -> (view by: large icons) -> Power Options. I'm on a Vista laptop now because I'm travelling, so you may have to hunt a bit; however, on Vista, in the left column of Power Options is "Choose what the power buttons do."In Windows 7, you may have to choose advanced options for the selected power plan, then scroll down looking for "power button" option and set it to "Shutdown."I hope this helps.

A friend of mine has to press the power button twice to start his computer. The first time it acts like it's going to start up and then stops before window Vista loads . After he starts it again, it comes to the screen where it informs him that windows vista didn't start properly the first time and of course follows wiith the options. He simply clicks start normally and it then starts up. Any idea whats happening? Could his power supply be going?

Answer:Has to press power button twice to start computer.

Does this happen the exact same way every time as you describe it or can it take longer/shorter for it to require a second boot? This would help to indicate whether it's a power issue or something perhaps hard drive related with loading system files on vista startup. Try getting into safe mode on the first try and see if this still happens, and if it does not then it is probably a system file issue and would need to run chkdsk.

I know you guys are good on this forum because you have helped me with numberous issues over the last 10 years or so. Any, my HP Pavillion P7-1020 sjust started to act up a little. In the MORNING ONLY, I have to push the power button twice. The first time I push it hte light turns on then off. I push it again and the PC boots up like it should. Over the past few weeks, I have inserted a Blue Ray writer and then changed the cable from VGA to DVI-I. That is when it appeared to start the issue. It does not seem possible that the DVI cable would cause this unless the software on the onboard PC changed. About 4 months ago, I added an additional USB card to give me more slots. had no issues after that. Its only been recently after the Blue Ray. Just wondering where I should start first. Is is a cmos battery going bad. Is it not enough power from the PSU or am I starting with a new issued.
Looking forward to seeing responses. Because its a morning issue only, this may take a while to solve if I have to start disconnecting things. That is why I want you opinion on a place to start.

Why can't there be a reduced power profile that would allow the 90W adapter to be used while the system is running? I've tried multiple parameters, but the Power Manager keeps complaining that the wrong adapter is attached and will not keep the battery charging while the system load is around 10-15 W. Worse, it seems that the system will not use it at all and the battery keeps discharging! This makes no sense at all.  That load is certainly within the adapter's capability and to keep the battery topped off while on an airplane. Even worse, the battery will not charge even if the system is sleeping!! Only a complete shutdown will allow the battery to charge. The message from Power Manager states: "This AC adapter may not provide enough power for your ThinkPad....." In fact, it is not even permitted to provide any power while the system is powered on! Sounds like there was the intent to allow the adapter to be used, but was not fully implemented?  I thought that BIOS 1.32 would allow for this because of the following statements in the README file: [New functions or enhancements] - Improved system performance when a heavy software was executed with the 65W AC adapter. - Added support for Airplane in-seat power mode of ThinkVantage Power Manager.

The 170W adapter provided with the W520 is excessively large and heavy, and draws too much power from seat power outlets or car ligher jacks.I have been using a W510 with a 90W travel adapter for over a year with no issues. I ran it in power optimized mode, and there was never a problem. I just recieved a W520, and it appears to be unable to use any of the 90W adapters power. Here's how I determined that: In the power manager battery tab, it displays the real-time battery output. In the power source optimized mode with the screen dimmed slightly, it reports about 12W of power draw from the battery with the system relatively idle.  If I plug in the 90W adapter, a message appears above saying the adapter may not have enough power, but the battery drain does not change. It remains at about 12W.  Unplug the adapter, and the warning goes away, but it still does not change the power drain. It appears that the system is drawing 12W from the battery when 90W is available on the power connector.  While running and connected to the 90W adapter, the batteyr symbol is display, and time remaining steadily drops indicating it is really using the battery. What am I missing here? This seems crazy to drain the battery when adequate power for the current mode of operation is available from the adapter. Of course, if there is a surge in activity and the power drain exceeds the adapter's capacity, then in that case it would be necessary to use the battery to ma... Read more

This problem only started around last week, but I have also had it in the past.
Whenever I shut the lid of my laptop (which I have set for the laptop to to enter sleep mode), it seems to sleep normally (i.e. the fan turns off and the power button blinks to indicate the laptop is still on). However, it actually shuts itself off.
This also occurs if I let the computer idle until it would normally enter sleep mode, or if I press the power button (without holding it down).
In power settings I have the laptop set to go into sleep mode when I shut the lid or tap the power button, under all battery conditions. I have tried resetting the power settings, and have already used the system file checker to check for corrupted files (of which there were none). I have also used the power troubleshooter to fix issues and nothing happened.
I use an HP Pavilion x360 Convertible, and I run Windows 10 Home Edition (64 bit).
Any help would be very much appreciated. Thanks!

Hi, I have an issue with my ThinkPad W520. It looks like the power button stopped working. I was using it at the office on the docking station. I noticed once that it didn't start by pressing the power button. Didn't think much of it, pressed the docking station power button and it started and I could work normally. Then, I forgot about it, shut down and went back home. Now, I see I can't power up the machine. (I don't have a docking station here). I tried the manoeuver of pressing the buttons often and keeping them pressed to discharge the caps as I read in some threads. Also took off the batteries and let it like that for 24hours. Didn't change anything. Any idea what can go wrong and what I could do? I don't have a docking station here. Is the button dead?

Hi guys well I just hope someone with some electronics knowledge in repairing notebooks would help me out in here.
I got a sager 5680 lappy, and when I plug the lap on AC power without the battery I turn on the unit and instantly goes off, ( I hear a low sparky noise like some sort of short circuit, when this happens the psu light dimms from rock solid ) .
Now if you leave the unit with the battery charging you may be lucky and the battery will charge and the only way the unit works is with the battery on it's bay, as soon as you remove the battery boom unit shuts off.

The Unit does work but only when you plug in a battery and when it charges if you leave it dunno a couple of nights never gets solid green

What I did :

- Could the PSU be bad not throwing enough amps ? even if it shows voltage
on digital meter

- This lap has a separate voltage daughtercard for the battery I removed it when diagnosing this card goes
plugged onto the mainboard and here the battery gets plugged.

- Measured PSU voltage it's working fine 20volts DC

- Checked SMD fuse on motherboard , fine

- Dissasembled the entire unit ripped everything off that might me faulty

The power adapters and the power sockets have an extremely high failure rate in the Sager 5680 laptop. We have seen eight of them in our shop with identical symptoms. While still under warranty, Sager replaced those without a question.

The problem appears to be where the power meets the motherboard. New parts would need to be re-soldered into the system... expensive because it is very time consuming.

Sorry I don't have a solution for you. Working units are available on eBay, if you want to trace the problem between a working model and a failed one.

Hey guys, just a shot in the dark question, but:

I put a fresh install of windows 7 64-bit on this PC I built for my sister, and everything appears to go fine. However, after updating the bios, and installing the gfx card drivers, she tells me that when she presses the power on button, she gets a blue screen, the computer reboots, and then everything is fine.

Ideas as to what that might mean? If this is too little to go on, I'll head over there asap and go through the whole process, I just want a starting point.

Thank you for your time

Small edit: the system specs of my profile are the ones for her computer.

Answer:Press power button, blue screen after beep, then fine.

Check for a dump report. If you have one post it.

Hi everyone,

I'm a big dumbie and accidentally spilt a tiny (and I mean minuscule) amount of water that ended up trickling into my PC. Whoops. It wouldn't turn on after that so I thought maybe the graphics card was shot.

It wasn't the graphics card. The graphics card is fine. I replaced the motherboard, and in the process, the PSU died. I replaced the PSU, now I get the blue screen of death every time after boot that says "Check for viruses on your computer. Remove any newly installed hard drives or hard drive controllers. Check your hard drive to make sure it is properly configured and terminated. Run CHKDSK /F to check for hard drive corruption, and then restart your computer."

I'm assuming I get that message because I had tested the hard drive while trying to figure out what was damaged by the water in another computer, and it worked fine.

I reseated the battery in the motherboard to reset the CMOS. I reseated the CPU to fix a 'CPU fan error' message that was occuring (bent CPU pin). I moved around sticks of ram., only used one stick, different slots, both sticks, different slots.

What do I need to do to get my computer working again?

Here's what I have (that I think is relevant):
Power Supply 500 Watts
Hard Drive 1TB - SATA III - 7200 rpm
Motherboard Chipset ASUS M5A97 R2.0 AM3+ AMD 970 + SB950 SATA 5Gb/s USH 3.0 ATX AMD Motherboard with UEFI BIOS

Thank you for any and all help.

Answer:W520 power adapter issues: 170w unit seen as 90w

Hi, sameer_AQG
I have a few questions for clarification:
From this page on the support website, I do not think that a 170w power adapter is compatible with the W520. Is the machine only charging when powered off, or is this only with one power adapter?

Hello, I just bought on ebay from a german seller a power adapter for my Lenovo W520 since the one I have isn't working very well anymore.Fact is I strongly suspect the one I bought is not original, the case feels flimsy, the sticker on the back is different from the adapter I got with the laptop, it has a 3 prongs plug instead of 2 prongs and it's also slightly wider and thicker.I'm getting ready to file a reclaim on that product as soon as you will confirm it is fake as I suspect, on the ebay page it was stating it was a new original power adapter.Here is the link to picture I just took of the sticker on the back side of adapter I received: you for your help

Ok, so my w520 boots up when the adapter is connected. if i remove the adapter and keep the battery on, it boots. but if i remove the adapter and battery and then put the battery back on, it wont boot. but after that, if i add the adapter, it revives itself. what is the problem? because i find it annoying if i remove the the battery, the machine wont work anymore and then i  have to get my adapter to revive it heres some information. i spilt water on the keyboard and then wiped it clean but made a mistake and turn it back on thinking it was fine and left the battery in. (there was no adapter at the time) the machine shutdown after a while so i left it off. but i left the battery inside. i spent a day drying it and it ran normal. this is the first probelm ive encountered sincealso, ive dropped my laptop a few times, i was wondering if it was the cause of it randomly shutting down (before water incident) when i picked up the laptop, it would just turn off. sometimes if i put it to sleep and carry it around, it wont resume again. all this happens even when adapter is connectedalsowhen i connect the adapter after the machine isnt able to boot, the battery light flashes a few times before the light turns off. what does that mean so is the motherboard damaged? and about the battery boot problem, is it something inside that damaged or is it the battery?

Answer:Cannot boot w520 when on battery after removing power

From my experience with W series machines, I would say something must have shorted out when you spilled water on the machine. Although a drop is also capable of destroying an internal component. Honestly this seems like a hardware issue and very difficult to debug online, I would just file a warranty claim. From my experience with Lenovo Warranty they are very prompt and they will probably end up swapping your board if anything. Also, if you have the finger print reader enabled, try to power-on the machine using the finger print reader (Option is in BIOS and Windows) and see if that works, it could just be when you spilled water on the keyboard you ruined the power button and its no longer working properly?. Could just require a keyboard swap. (Takes 2 minutes to do it). Let us know.

My husband and I have the same identical laptops. His wakes from sleep mode by pressing a button on the keyboard or moving the mouse.  Mine does not.  I can only wake it by pressing the power button.  I have reset to default power settings and it still doesn't work.  I have gone through keyboard properties and have found nothing that says anything about sleep or wake.  The power button wires have severed (which is normal for this junky laptop, or so I hear) and so in order to turn it on and off, I have to press the wires together.  In order to avoid doing this often, I wanted to put my computer in sleep mode and be able to wake it up with the keyboard.  But, as mentioned above, I am unable to.

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. But the problem is, the screen to my monitor is blank. I also noticed that my usb aren't working (mouse connection light isn't on). I tried a soft power off by holding down the power button but no luck. The system does not turn off no matter how long I hold it. The only way to turn it off is by pulling the power supply cord or turning the power supply switch off.

My pc build:

AMD FX-6300 3.5GHz Socket AM3+ 6 core processor

Prolimatech PRO Panther 120mm CPU Cooler

THE PROBLEM: Computer turn on with everything running as usual, but shows blank screen on monitor. Cannot soft power off by pressing power button.

Things I tried:

Clear CMOS by removing battery and switching pins
Running with 1 4GB RAM instead of 2, move the ram around the slots & alternate which Ram is used.

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


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.

PowerEdge T20 won't power up, power button & fans repeatedly turn on/off forever
1 year old. Press the power button, power button lights up amber, then white, CPU fan spins up briefly, then a beep and the power button turns off and the fan shuts down. Three seconds later the cycle repeats forever until I depress the power button for 5 seconds.
Is this a bad power supply? A bad motherboard?

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:

The motherboard has a 3 volt battery installed in it. This battery provides just enough power to retain all of the BIOS settings regardless of the state of the main power or the power supply. Following the steps above will not reset the BIOS or the CMOS chip.

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:
2b - remove the 3v battery.
But it will not clear the CMOS.

Hoping someone here can offer some advice? I own a Dell studio xps 435t-9000 that is a couple years old. I recently replaced my harddrive and since then (don't know if it's a coincidence or not) I'm having another problem. 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. Finally the last time I checked all the plugs I also took out the board batter for a few minutes to try and "reset" things. Not sure if that matters, either.

So, I'm at a loss where to go from here. I could replace the power su... Read more

Here is how you get around the on battery max frequency limitation (of 1.2 GHz, at least for my i7-2620M) and no turbo (well, almost, read on): 0. Assuming you have max performance enabled everywhere possible (BIOS/PowerManager/Windows Power Scheme)1. Load ThrottleStop.2. Set the multiplier manually to your maximum multiplier (e.g., 27x for i7-2620M, 23x for i7-2820QM, etc...) or Turbo (which is the setting after your max multiplier).3a. Enable ThrottleStop3b. (optional) Check in CPU-Z and make sure that your highest multiplier is being used when the CPU is utilized. If you selected Turbo, you should have turbo enabled at this point.4. Disable ThrottleStop5. Exit ThrottleStop, so that it doesn't waste any battery power, since it is no longer needed This will change the max frequency (and max multiplier) available from whatever Lenovo decided to arbitrarily fix it at (e.g., 1.2GHz) to the correct max frequency (which in my case is 2.7 GHz / 3.2 GHz for turbo). Now your laptop will be able to correctly go from 800MHz to whatever is the max frequency of your CPU, using both EIST and C1E. Turbo will also kick in, if you enabled it in ThrottleStop and the Lenovo PowerManager app will even show it as enabled. Thanks Unclewebb for letting us get around this stupid max CPU frequency limitation that Lenovo has imposed on us. Disclaimer:Do this at your own risk, since Lenovo does not officially support it.Turn on active cooling, if you do CPU intensive stuff for any...

Answer:W520: How to get full speed and turbo on battery power

Hi, I have the opposite problem - my i7-2720QM is fixed at 2.2GHz no matter how hard I spank 1, 2 or all cores, and no matter what System Performance settings I apply.  It even runs at this speed, and gives the same bench marks when on battery  with the "system performance" set to Low.     No one even knows what the various System Performance settings actuall mean. E.g. Neither Lenvo support nor these forums could tell me what the difference between "Maximum Turbo","Turbo" or even "Low" under "System Performance" in the Lenovo power manager Advanced settings. I have been trying go get turbo boost to work for 2 months. I have wasted so much time with this machine, I could have bought 2 Macbook pros for the cost of the time lost. I dont know why Lenovo have disabled the turbo boost (and the opposite, turbo drop?)  feature for this CPU - is it deliberate, or incompetence?  Its certainly false marketing and extremely annoying that I have to use my ancient PC to do single threaded type work which I know the Laptop can manage if it were not crippled. So people whos clock speed drops when on battery are the lucky ones.  Mone doesnt even if I want it to.
