SYS technology, inc LCD monitor, no pic, clicking w/ flashing power light

Question: SYS technology, inc LCD monitor, no pic, clicking w/ flashing power light

A friend says this SYS Technology, Inc. monitor was working last time he used it, gave it to me. Does not have DVI, just VGA cable. Model SYS-15L-C-JT, label says it was made April 2002. I cannot find any SYS tech support. I'm looking to see if this thing is dead or if what's wrong is something simple or what. Is there a diagnostic program I can download?

I have tried a few things, like changing the sequence of connections, but it seems not to respond to power button or other controls on front. Each time I plug it in to power source (whether or not it's connected to PC) power light flashes green and it clicks every second or so. There is no picture nor status message onscreen.

An elderly neighbour turned this monitor off at the wall socket. Now, when turned on, the leds around the power switch light yellow briefly - then flashes blue 4 times then steady blue for about 15 secs. The cycle then repeats. It looks to me as though it needs a reset somehow. Google not too much help. I've tried holding a combination of the front buttons while powering on to no effect.Anyone any ideas, please?

Hi My F1904 monitor seems to have a fault. When I power it on the power switch flashes amber and I get no display. Any suggestions? There does not seem to be any mention of this in the documentation. Many Thanks 

Answer:F1904 Monitor flashing amber power light

amber usually means sleep mode. flashing can mean different things. Disconnect the video cable, turn it off, pull the power plug, wait 10 seconds, plug it in and turn it on. Press the OSD buttons to see if you can bring up the on screen display. If that comes, up try connecting it again. Hopefully the PC is not sending out a bad video signal.

Yesterday we had a thunderstorm and the power flickered a couple times. Today I tried to turn on my computer and the red light on the motherboard flashes and then turns off so my computer won't turn on. When I push the power button and keep it pushed in, it makes a clicking noise and the light keeps flashing.

There's also a green light at the top, sometimes it flashes when I plug in the power cord and sometimes it doesn't. None of the fans start running.

Answer:Flashing red light & clicking noise

Did you have your computer plugged into a decent surge protector? (sounds like it wasn't based on what you described)

It will be quite difficult to tell you exactly what the problem is in this case, but I would be the electricity has created a surge that has damaged some hardware. First, check the power supply. If you can swap out your current with a known good PSU, that could help troubleshoot. If you get the same problem afterwards, your motherboard could be faulty.

When you say a "clicking noise"...where exactly is that noise coming from?

This is a first for my monitor, but this morning when I turned it on it quickly began to flash bright horizontal lines randomly on the screen with an audible clicking noise per horizontal blip. Now it is phasing in and out of being blurry with the same clicking noise. However, just as I am writing this I just received a laser light show of blips. So, it seems to be going back and forth between blips and fuzzy.

Any thoughts? I am working on a Dell Precision 530 Workstation and the monitor is a Sony Trinitron. I am checking on Dell's website, but I haven't found any definite solution yet.

I am working with WinXP and the video card is an NVIDIA Quadro4 700 XGL. Thanks.

I came back to my computter after a few hours- the CPU had powered down Sori for the long gab, here it comes--

I poweredup and there is 30 seconds of HDD activity (normally 120 secs), the power button light on the front panel is blinking at me (it's usually steady), and there is no apparent bootup. My monitor stays blank except for the "On Screen Display" setup menu. Keyboard inputs have no effect, like Cntl/Alt/Del achieves nothing. No F5 or F8 to safe mode.

My digits are crossed that Disaster may not have struck, cuz:

3 hours before it auto-powered down, i had upped the display to just 1024x768 from 800x600, using the same Nvidia "optimal" refresh rate, and used it for an hour with no apparent problems.

Both my monitor, a Princeton Ultra 73e 17" CRT, and video card, a Nvidia/Jaton GeForce2 MX400 3D, claim to easily handle that measly 1024x768 rez. Everything is 3 years old, tho 'should' have many hours left.

I haven't yet swapped monitors/cpus, cuz that is going to be a lousy dismemberment of my wall cabinets. Anyone have an idea about the blinking power light on the CPU. {i fear the worst, but i'm a pissimist}

Answer:Flashing Power Light CPU, ruh-roh?

Your probably going to have to open up your case. Are the fans spinning? Also, you may have to try a different cpu.(I know you dont want to) If it works with another cpu, then you know. If the fans arent spinning, i would try new ones. Swapping Power supplys if available. If all else fails, im thinking your mobo died.

(because i had just reformated it and my linksys wireless wasnt working and i was gona call them, anyways...) i pluged the power cord right into the wall, pressed the power button, and no go. i checked the cord and it was pluged in, then i noticed the power light (right under the cord connection in the back) was flashing (not rapidly, like once a second, idk if that matters). i brought it back into my room and pluged it in where i always had and it still wouldnt power up. the only thing i can think of is that my powersupply might have got a surge, so before i buy one, i thought there might look into other possible answers. any suggestions would be appreciated! thanks  notes: the computer was off when i unplugged iti dont know anything about power supplies. hahaif u need any info on it though i can provide it (i do know where that is)

My monitor light is flashing on and off when I boot up my PC and also when the PC is off.
It's done this before but I can't remember how I fixed it.
Any ideas people?

Answer:Flashing monitor light?

First thing to check is that the monitor cable is connected correctly. Power down the system and unplug the monitor cable from the system. Look at the end of the cable and check for any bent or pushed in pins. Reattach the cable to the computer and power up the system.

Can anyone tell me what's going on with my monitor?
I have an HP Pavilion M70 monitor.
My power light keeps flashing and there's a clicking
sound (sounds like a relay clicking). Pressing the power
button or any other button does nothing.

Answer:Power light on HP Pavilion M70 keeps flashing

Sounds like a power supply shutdown. It happens when there is a major component failure which causes the power supply to keep resetting and trying again (the "clicking" you hear)

Needs servicing or scrapping.
Monitors are usually not often worth fixing these days, unless it is very minor (and that does not sound minor)

Battery/mains light which is normally either red needing battery charge or green when fully charged has suddenly started flashing red.
Any suggestions please

Answer:Asus lap top power light flashing red

Whats the power level showing on the laptop, just using the battery. Then check with power lead to the mains connected.
You might find that a possible check, is to run the battery down, then try a full
recharge. If this doesn't improve the situation, then a new battery might be required, or alternatively it might be something else, which another member might know about.

I bought my XPS8900 a couple weeks ago, and immediately upgraded the memory to 32GB.
Everything worked fine, but I then decided to upgrade the video card to an EVGA GeForce GTX970 SSC.
This card requires both a 6 and an 8 pin power connector which the stock Dell PSU doesn't provide. So rather than return the video card, I upgraded the PSU to a Corsair CX750M, which I've read other XPS8900 users have had success with in this machine.
As others have reported, this PSU is a tight fit, but I was able to get it installed. As soon as I powered it on, my problems began.
The case and CPU fans spin, I can hear the HDD spinning up, and I can open and close the dvd tray. So I know the PSU is at least providing some power. But I get no video, and the power indicator on the top of the case flashes an amber pattern.
I've tried reverting back to the stock dell PSU and video card, but still have the exact same issue. 
I've also tried unplugging the power cable and holding the power button for 30 sec. But still, the power light flashes the amber pattern.
I know there are no beep codes for the XPS 8900, and that the power light's amber flash pattern is used instead to diagnose the issue, but I haven't been able to locate any reference to what the patterns indicate.
The power indicator flashes a 2 - 7 pattern, and repeats.
Does anyone know what this means?

Answer:XPS 8900 Flashing Power Light

I had ripped everything out with no luck. Well, everything except the upgraded memory. It had been working, so I didn't think it would be necessary to remove it. But I was wrong.
I reverted back to the stock memory and the blinking amber light problem went away!
Then I re-installed the new memory, and it also worked!
So I guess it was just that the memory needed to be re-seated.
Not sure if the 2 - 7 pattern means "Memory issue", but that would be my guess.
Since the XPS 8900 doesn't support beep codes, I hope Dell will eventually publish what the flashing light patterns mean.

i have this problem it just start like yesterday and when i turn on my computer it sounds like its booting up like normal except the monitor will just blink with a green light and i checked to make sure the cords and everything was good and it still dont work.

Answer:green flashing light on monitor

A light blinking at a rate of at least once every second often seems to be made to indicate there is a problem, as in the makers of the device that has the light did it to show that there is a problem, so at least the monitor "knows" there is a problem...So maybe you should read the manual or contact the manufacturer and see what the blinking light means.
First things I would try are to plug it into a different PC, trying a different data cable, a different power cord, and a different outlet. If all of the above fails (including reading the manual or contacting the mfr.), it is probably a part inside the monitor not working correctly. Make sure all connections are secure, and not crooked or anything, including the video card's (if there is one) connection the the motherboard's slot, any internal power cord to the video card, etc.

Gateway DX4640 desktop froze in the middle of viewing

It required a hard re-boot. Now I get a slow flashing power light. Fan starts but it won?t boot. I tried bootable CD with no success, although the CD drive does spin when a CD is inside.

We tried the following:
1. unplugging power and then depressing power bottom for a minute to discharge battery.
2. pulling out the memory cards one at a time, and then booted with just one memory card at a time without success.
3. removed battery and reinserted after 10 minutes

I would appreciate any advice you might have.

Answer:Slow Flashing power light – no boot

This is a common issue with Gateway machines, it is down to the onboard Video chip overheating and failing, though this mostly happens with laptops!! have you got a spare vid card lying around or can you borrow one from another machine and try it in agp/pci/pcie expansion slot, to rule it out ??

I just bought a M100 laptop a few weeks back and it's been fine. The other day I was fiddling with the Toshiba Password Utility which I ran from within XP. I set a password on it for what I think was the power on function. I then restarted the machine and lo and behold it no longer boots.

When I turn it on, the power light (2nd from the left, between the AC-in and battery) turns on green as normal for a split second, then flashes orange in a steady on off pattern. There is no display, no hard disk activity, and it won't power off unless I hold the button for 10 seconds. The fan also seems to blow on high speed straight away, which doesn't normally happen.

I've tried it with and without battery, without hard drive, without RAM and without cmos battery. Same problem every time! I can't even get to the TOSHIBA boot splash screen.

Someone pleeease help me. I'm at a loss as to what else it could be. Also, no-one on the net seems to have reported this problem before.

Thanks in advance to anyone that can help.

More details: The capslock button light doesn't respond but the FN key light does. Pressing any button on the keyboard results in a slightly delayed beep.

Answer:M100 - Flashing power light (not ac or battery).


Well, first of all the Toshiba Password Utility allows you to set the two levels of password security ? user password and supervisor password. This feature prevents unauthorized access to your computer.
Which password did you set?
As far as I know there are two ways to start the computer:
Insert a password token before you turn on the computer. The computer will start normally, without displaying a password prompt or enter the password manually.

Furthermore the second light from the left side is a power indicator. It glows green when the computer is on. If you turn off the computer in resume mode, this indicator blinks orange (one second on, two second off) while the computer shuts down.

Well, I don?t know why you can?t boot the unit, but please check also the password settings in the BIOS. There you can try to delete this password.

Hello, I'm trying to figure out if the power supply on my hp is bad or not. The green light on back of the tower is flashing and the computer won't turn on. I've tried all of the preliminary things and nothing works -- the green light keeps blinking until I disconnect the large plug to the motherboard, then the light stays on and doesn't blink. Once I have the power cord disconnected and the main plug to the motherboard disconnected as well, I then have tried replugging the power cord and then replugging the main plug to the motherboard (kind of trying to jump start it), the fan tries to come one (but only for a second, then goes back off, so it won't boot).Does anyone know if this means that the power supply is bad or if something else might be wrong? I'm wondering if the power supply would be bad when the computer is clearly trying to start, but not quite making it.

Answer:no power and green light on my hp pavilion is flashing

If the PSU blinks it needs to be reset.unplug the electrical cable from the wall and the PSU.move the red voltage selector to the opposite position it is in and then slide it back. If you live in the USA 120Vac-->220Vac-->120Vac see the image below.  After you have done this you can plug the power cable back into the PSU.  Connect the power cable to the wall power. If the PSU is still serviceable it will no longer be blinking. Best regards,erico Edited to fix the broken image link.

Hi there,My son's computer recently started having this problem in which, after 5 minutes of the computer running, and running fine at that, it suddenly closes down immediately, but yet, is not switched off: the power button which usually is a constant green starts to slowly flash yellow and the only way to stop this is to switch the computer off. Whenever he switches it back on it does the same thing, works fine for 5 minutes and then switches to nothing but the flashing yellow light, we have even tried it in safe mode and the same thing happens.Just to give some info which might help you, the computer is a Dell Dimension 5000 running windows xp home edition. The last time before the problem started, the computer had been left on for around 20 hours, and this has been happening for around 12 hours now. He did replace his graphics card recently, but that was 3 months ago and he hasn't noticed anything wrong with it in that timeIs this easily fixable or will a professional have to be brought in, and if so would it just be worth backing up the necessary dataand buying a laptop to replace it, as he is off to university in a couple of years so will need a new computer soon anyway.Well thank you in advance, just ask if you need anymore information about the computer, i'll do my best.Thanks!

It starts to flash when I try to power on and will not finish until I take both battery and power supply out.

Answer:Flashing power light on Portege M200


When the notebook has a problem with power supply (board electronic), sends hexadecimal code.
In your case there are two problems:

- To know what this code means you must know exactly how to read this code. The binary code must be converted to the hexadecimal code and then you could compare the code with the description in the maintenance manual.
- Maintenance manual is not a public document.

Unfortunately there is nothing you can do alone. please contact nearest Toshiba authorized service provider and let them check your notebook.

Luckily it was only water she threw over it rather than any sugary/caffinated PCB eating liquid though it was switched on at the time.

Dismantled it the best I could and left it to dry yesterday, most of the impact seems to be the front left (hard-drive bay was swimming) so the chip on the far right and memroy in the middle seem to have avoided any water entry.

This morning when i reconnected everything it, farily predicatably, didn't switch back on from battery power. When I plugged the mains in (at arms length) the mains indicator started flashing orange - two short, one long, two short, one long and then two short.

Have had a quick flick through the user manual and the only reference to the flashing orange PSU light is for overheating and that inferes there's no pattern to the flashig, just that it will continue until it reaches a safe temp.

I'm pretty sure the wee thing is borked but was wondering what the power light indicated and then by extension if that means there's any parts I can salvage as spares (like it may denote the memory's still ok or the chip and such).


Answer:Flashing Power Light on Tecra A3X (PTA3XE)

Hm, sounds the motherboard was screwed up. I am not sure, but if you?re really sure that everything is connected well and so on, it should work.
Maybe the motherboard did get a little splash from that "drink-action".

The problem with liquids and notebooks is they won?t collaborate together and after some "liquid-spilling" times a PCB can get a short-circuit from any device which had contact with the liquid.

My opinion: PCB is gone. But thats just a theory. :)

My laptop has recently developed a problem with the power light which starts to flash about an hour after I have turned the laptop on. I have ploughed through the manuals but can find no explanation.

Hi, my laptop won't power up. There is a flashing white LED next to the in jack where the AC Adaptor plugs into.  The light flashes 3 times. The light is not on the adapter, it's on the laptop. I left the laptop plugged into the power supply all day, went out and now it won't power up. Thanks,monks

Answer:Flashing white light next to power input

Hello, Please try hard reset first :  Shut down the notebook, unplug the AC Adapter and then remove the battery.  Hold  down the Power button for a full minute.  Plug in the AC Adapter ( leave the battery out for the moment ) and see if the notebook will start.  You might want to take a look at this document: Battery Does not Power Notebook or Hold a Charge. It suggests troubleshooting steps to determine if the problem is the battery, the power supply, or the system board.You might find the answer to your battery/power issue as you work through the steps in that HP support article. Hope this helps, for any further queries reply to the post and feel free to join us again  **Click the White Thumbs Up Button on the right to say Thanks**Make it easier for other people to find solutions by marking a Reply 'Accept as Solution' if it solves your problem. Thank You,GBL84I am not an HP Employee

I have just been handed a computer from my next door neighbour, it seems to be a home build (or a computer shop build) so im unsure of the exact specs as it is not booting, they are telling me that until yesterday it was working fine... but now it will not start..

All I can tell from opening it up is that it is XP, has an Eagle power supply, a winfast motherboard and 512mb of Dan electric Ram..

when you switch the system on all the fans start and the hard drive spins up, but then there is one beep and the green power led on the front of the case goes from constant green to flashing green and nothing else happens..

I have removed and checked the HD wich is fine, I have reseated the RAM and even changed it from DIMM 1 to DIMM 2, but none of this makes any difference..

Could it be a power supply fault or a Motherboard fault?? or even a graphics card fault?? how can I find out which it is??

I have asked my neighbours if they still have the user manuals but they claim they threw them out when they moved in about 3 years ago...

Can anyone help??

Many Thanks

This change occurred in the midst of a printing project. The power light continually flashes (this is not a jammed, out-of-paper, etc. warning). The driver has been uninstalled & then reinstalled several times, cable & power cords have been checked, unplugged & replugged multiple times. Could this indicate that the printer is just worn out?

The monitor acted as if it wasn't attached to the computer, and the computer didn't "tick" like it usually does when loading windows. The only thing I got was a flashing "power light". The "database write" light was also on, but it was constant"

I think its a loose connection inside the tower.

Assuming that the monitor in question is a LCD ?
You could hold a torch up close to the screen and if you can see the normal screen (the one that's there normally there when your computer boots) then the problem is the back-light for the screen -may be repairable.

However you might also find on the monitor manufacturers site a list of "Blink-codes" which will be interpretative in much the same way as Morse Code. And this may have implications to what is actually wrong internally with the unit.

I am dazed with this problem. Trying to find the solution on all the forums.

My brother owns a Dell Desktop computer and suddenly it stopped working.

- The Power button light is flashing continuously.
- The green light on the motherboard is perfectly on.
- The port light where the telephone wire goes and the usb port next to it on the motherboard is blinking continuously.
- The processor is not starting.
- If I remove the power cord, the lights mentioned above and same for 15 seconds.

What must be the possible problem.

MAny Thanks in advance


Answer:Dell PC not starting: amber flashing power light

You would be dazed again, because this is probably caused by a failing power supply. The blinking power button is a good clue. The green LED on the motherboard simply means that you have a power cord plugged in... It could be a bad motherboard too, but power supplies are easier to replace and cheaper to start with

I can't get my computer to boot at all, not into CMOS, not anything. It doesn't power up. And the green LED light that comes with the power supply is constantly flashing.

This has happened before, normally when I wait a while before trying to boot, I can get the fan inside the power supply to spin just a little bit. The last time it happened, I fixed it by taking out one of the memory sticks.

I have no other power supply to test, so I don't know whether it's a problem with the motherboard, or the power supply. However, I notice that when the 24-count connector pin isn't connected to the motherboard, the light doesn't flash, it just stays lit green. When I plug it in, it starts flashing again. Maybe it's the motherboard, maybe the pins are bad, I'm not sure what that suggests.

Is there anything I can do to diagnose this clearer?

So several months ago my laptop started to have a problem where periodically the power light would begin flashing as well as the charging light. The power light would blink a while color that it normally is and the charging light would blink orange. When this happens the battery will stop charging, but will occasionally resume if I unplug and replug the power. I don't think this is a battery related problem because if I try to boot up my latpop without the battery in, it will get half way through then it will just shut off. I should note that when the battery is plugged in I have the flashing light problem during start up but it will usually be fixed with unplugging and replugging the power cord a time or two. This is a really frustrating problem and really limits what I can use my laptop for these days and I'd like to see if it's something that can be fixed at a reasonable cost.

My sister-in-law has an eMachine that she turned off and unplugged before leaving for vacation. A week later she returned and plugged it back in only to find it won't turn on. I don't know much about this pc other than it's a tower and about 3 or so years old. I figured it was probably the PSU (power supply) but wanted to verify as many things as possible. Basically, there is a green light on the back of the pc (on the PSU) that will flashes on and off when you try to turn on the computer. The PSU fan doesn't spin and nothing else makes any attempt to turn...just dead.

I pulled all the power connectors and jumpered the power switch pins (15-16), this gave me a solid green light on the PSU and the fan spun normally. I tested with a voltmeter and got the proper voltage on all the pins. I am thinking that this probably rules out the PSU but not 100% as something could be 'pulling it down'???

Any ideas on what else to look at? I hate to buy a PSU when it appears this one is ok. That pretty much leaves the MoBo and/or CPU. I've pulled all the cards and memory trying to get it to do anything and nothing affects it. I suspect there is something wrong with the MoBo but don't know how to verify that.

Any help or advice is appreciated. Thanks!

Hello, Last month a message from lenovo power manager software pops up on the laptop, saying something like my power adapter needs to be replaced it is not providing enough. It continued to work for a few days before stop charging at all. When I plugged in to AC power, my Yoga would start charging for 2 seconds and stop. If I took out the plug and reconnect, it just did the same and not charge. While plugged in, the laptop charging icon disappears after the 2 initial seconds and the power light on my pc flashes steadly on/off amber. I managed to order this power adapter here before out of battery. When I received the adapter my Yoga started charging again with no problem. The next day however, my screen went black and stop working. Warrenty out dated, so I openned the machine and found a loose screw from the fan, put it back and by magic the screen is working again. The next day I plug in my laptop, let it charges for a few hours. When I turn it on the charging icon disappears again. Same thing as before, not charging with flashing amber light. I noticed that when unplugged, the light would go to solid white like normal. So I have 70% battery left before I feel like just throwing this thing in the trash! I couldn't find anybody with the same problem. I was wondering if updating the BIOS could help but when I tried a message came up "Please plugin and try again", Great...! Someone please help!

Answer:Yoga 2 13 - stopped charging - power light flashing amber

Hi pjz,
Welcome to Lenovo Community Forums!
I would suggest try isolating if Battery or AC is causing this problem.
First is to try removing the battery on your Yoga
Here's is a simple guide.
Now while there is no battery Try plugging your adapter and try turning the computer ON.
It should power up using only the AC adapter.
If it did not.
 Your problem lies with the the power System, COuld be the charging port. Try observing the Port or follow the wire that runs to it.
If the computer power up without the Battery in it, without any problem. This is a problem with your battery.
Let me know your findings

We got a Compaq Presario S6500NX from a friend who had upgraded to another computer and we can't get it to work. It ran fine before he brought it to us, however, once we got it here and tried to power it up it wouldn't start at all.

On the power supply in the back the green light blinks and clicks rapidly when the cord is plugged in, and pressing the power button does nothing at all.

Interestingly, a few minutes ago I took it out of storage, (we got the computer months ago and gave up when we couldn't get it running) plugged it in by itself and it powered up just fine, the fan turned on and everything! So I opened it up and cleaned out some of the dust (I didn't have it plugged into a monitor or anything, I just wanted to see if it was still doing the same thing it had months ago) and, lo and behold, when I tried to turn it on again with everything plugged in, I got the blinking/clicking green light and no power up.

What could be the problem here? I know the whole thing isn't totally shot because it DID power up just fine a few minutes ago. But now we're back to the blinking clicking light (instead of the steady green glow that usually happens when the power supply cord is plugged in). It leads me to believe that something's loose, but I don't dare mess with the power supply box unless I know what I'm doing...

I have a satellite A105-4054, which has given excellent service. Yesterday, the power light started flashing amber and stopped charging the battery. I had a second freshly charged battery, which I used instead and the power light still flashes amber.

I checked the Original Toshiba battery charger, which came with the unit, with a voltmeter and it shows 15 volts, which is correct. The laptop will boot normally with a freshly charged battery, but it will not charge when plugged in, and the power light flashes amber continually. If I remove the battery and leave the laptop plugged in, the power light flashes amber continually, and nothing happens (no power up). I would be happy to just run the laptop on AC, but that is not possible, right now

The toshiba power utility system tray icon, when the laptop is booted up on the fresh battery, flashes back and forth between charging and battery, and the battery does not seem to charge. Previously, the power utility would show AC power continuously when the unit was plugged in and the power light would stay blue.

I really like the laptop, since it has given superb service, and would like to keep it. Any reasonable solutions, please?

Thanks guys (and gals)!

Answer:Re: Satellite A105 - power light started flashing amber/battery not charging

On this virtual way nobody can say for sure what the problem is but after reading your detailed posting I think there is problem with power supply electronic placed on the mainboard. Only technicians with special diagnostic tools can say for sure what is wrong there.

In my opinion there is no much you can do about it and in such case whole mainboard must be exchanged. If you want contact nearest authorized service provider, explain the situation and I hope they can tell you more about that.

I just received my replacment AC adaptor. I put my battery back in and plugged the laptop in, but when i push the power button the battery indicator light flashes red four times. There are no lights on. Does this mean my battery is fried. Originally i thought the jack needed replaced, but the guy told me it was just my cord which Best Buy confirmed. So after getting the new cord i have this new problem. Usally there is a battery indicator light on when the battery is in and it is plugged in. I tryed taking out the battery, unplugging it and holding the power button down, but that didnt work. I also tryed it without the battery in. Is my battery just bad? Thanks for any help.

Thank you,

Answer:Solved: battery indicator light flashing red when power button on my laptop is pushed

Try plugging the laptop in and then push the power button. I have had the same thing happen to me when the laptop would only work when I had it plugged in. I had to replace the battery.

I have a hp split 13 x2 E8C05UAR#ABAWhen I use the tablet without keyboard and put it to sleep the white light near the charging plug flashes. I've checked the batteries and both are fully charged. Is this normal or a result of installing windows 10? While at sleep the white light will flash using up battery. If hooked up to the keyboard and put it asleep the white light on the keyboard near the charging plug flashes. Thank you for any information.

Hi! I hope you guys can help.
I've been trying for a while to set up a broadband connection at a friends house.It's a Thomson Speedtouch330 usb modem provided by the ISP.
Initially, the power light was green and the adsl light flashing green. I changed the filters, and 2 extension cables in case the problem lay there but the light kept flashing green. In desparation I phoned the ISP (it took about an hour to get through) and after making the usual checks they advised me to connect the tower unit plus modem directly into the master socket, as a way of checking the telephone line (If the asdl light kept flashing then there was a problem with the line, if it didn't there was a problem with the extension cable).
When I attached the tower/modem to the master socket all I ever got was a flashing RED power light, which really confused me. I thought that meant that the PC and modem were not talking to each other (which they were when using the extesion cable).
I'm no techie and am probably doing something stupid (it wouldn't be the first time, believe me ! ). But I'd be grateful if you could help. Thanks

Answer:Flashing green light then flashing red light !

I believe a flashing green DSL light is normal. What other symptoms do you have?

I have a LG TFT monitor from 2009. A fews days it was troublesome in getting a display. I pulled out and reconnected the VGA connector and rebooted. Eventually I got the display back. However now the power light flashes and there's no display.

Last night I left it running and it said something like 'no signal...' with circled circles. I rebooted a spare PC and it was working again. This morn it's back to a flashing power light and no display. Is the monitor finished?

Update: I left it running and connected to my spare PC for over 15 minutes and the display just returned. :confused

Answer:LG monitor power light flashes and no display.

If you can borrow another monitor and VGA cable, I'd hook it to the PC and see what happens.

If the other monitor shows the same problems, it's likely a problem with you PC's video card.

If the other monitor works, try the old one with the different VGA cable.

If neither of these solve them problem, the issue is with the old monitor itself.

when i turn on the computer the screen turns on for about 3 seconds, then it goes blank...but the power light is still on. when i turn the monitor off and turn it back on, the screen shows an image for 3 seconds again... its so frustrating!!! what can i do? please reply i dont want to go out to get it fixed by an idiot who charges 100s...

Answer:Blank Screen, But Monitor Power Light Still On

When the screen goes off do you hear the fans still running?

Make sure your monitor cable is tightly connected.

Start in safe mode (tap F8 when it first starts booting)

Does the screen stay on in safe mode?

This happens:

The horizontal lines disappear shortly after removing the power supply, and come back when it's reconnected.

Observations and steps taken:

- The computer has been connected to multiple power supplies in different rooms. This behavior happens regardless of the power supply.

- This doesn't start right away when the computer boots up - only after some time.

- It also doesn't seem to happen in safe mode, but I haven't tested it under heavy processor load in safe mode.

What is happening? What steps should I take?

Answer:Computer monitor has flashing horizontal lines when power supply is connected

A system restore resolved this temporarily, but the Windows Update which installed immediately afterwards caused it to start happening again.

Hello there!I've been using this monitor for 7 years and I have been encountering this problem for 2 years every time I start up my computer. Now I finally decided to seek solutions for this problem. My monitor power lights up for 3 secs and it disappear for 1-2 secs and lights up again for 3secs and this goes on for 10-15minutes before it could finally show the screen. So it is like 10-15 minutes of black screen and no sign of power. Pressing menu or other buttons doesn't work because it doesn't have any power in it. So I tried a different cord and it has the same problem. I tried a different monitor and both cords are working fine. It is only the monitor itself and I was wondering the monitor could be worn out or there's something wrong with the monitor.Thanks for reading and I hope to receive your help as soon as possible!

Hi,  Yesterday I came home and was about to use my T410 like I sometimes do. I turned it on, the computer loaded the ThinkPad screen and then quickly showed me a "Fan Error" in the top left corner. I took the computer apart and saw that the fan wasn't moving like it should. I tried to clean it without taking it apart any further but that didn't work so I took the fan out and cleaned it. It is now spinning smoothly again. However, after putting it back together, when I turn it on the power you can hear the laptop turn on but the screen stays black and there are no lights flashing on the monitor. My question is, why is my monitor not turning on?  Side note: While taking out the fan I swiped my finger on the thermal paste, I'm going to re-apply some thermal paste between the heat sink and the cpu later today (any suggestions on how I should clean the old thermal paste?) 

Answer:T410 - Black screen, power on, no light on monitor

Hallo and welcome to the forum You should remove any old thermal grease and apply new thermal grease before you turn the computer on. The Hardware Maintenance Manual (HMM) has instructions on how much thermal grease you should apply. To clean the cpu in my notebook before applying new thermal grease i have been using isopropyl alcohol in the past.

When I shutdown the vista PC the monitor power light stays green and a box saying, "self test feature check" floats all around the monitor. My XP machine after shutdown the power light turns amber with nothing being displayed.
Does anyone have any ideas? The monitor should hibernate when the PC is shutdown.

I recently returned home to find my monitor completely blank. At first I thought it was just in standby but when I tried to activate it, nothing happened. I checked all cables, unhooked the monitor, restarted the computer. . . still nothing. It is not the computer because I have hooked in an older monitor that works. . . sadly this monitor is about 10 years old and still running fine. The flat panel vs17e is only about 3 years old. Anybody else have issues like this? Is this typical of the hp 17 flat screens? If so, it is sad to see quality reduced as technology increases. Any help would be appreciated.thanks

Answer:flat panel hp vs17e, monitor is blank but power light is on

Have you tried another cable? The vga cables do fail.Here is a link to the manual for your monitor model.Try pressing the second button from the bottom on the side of your monitor. That is the auto-adjust feature.Message Edited by erico on 01-30-2009 01:09 PM

This happens off & on: My Gateway 5458E desktop will turn on, but the power light doesn't come on (should be blue) & there is no signal to the monitor. The computer powers up, can hear sounds (fan, etc), keyboard lights up, can see light from dvd player, but nothing on monitor & no power light. Have tried a different monitor with same results.The computer has also turned itself off while working ok a couple of times & wouldn't restart correctly until next day, but most of the time this happens when I try to do a restart or just turn on computer after being turned off.What could be causing it to start sometimes & not others?Thanks!

Answer:Gateway desktop turns on but power light not on & no signal to monitor.

A failing Power Supply sounds like the root cause of this issue.Any local computer store will be able to help you with one. The power supply is one of the most important parts of a computer.If they offer something really cheap, eg $30 it is not very good quality, the higher quality the better.Assuming you are using the machine as standard, a 350W PSU will cover you, however if you plan on getting a graphics card to play games or video edit ect a 500W minimum should be followed.
