Are you sure? Battery Saver always turned off the lights on my 920, regardless of update. (8.0 Update 3, 8.1, etc.)

I have a Lumia 1520 and the 3 capacitive buttons that did not light up after the Cyan update. The buttons do light up before the Cyan update and was fine in DP 8.1. In addition to that, I cannot access the touch menu in settings. When I tap it, it just goes in and exits the menu quickly (like refreshing the setting page).

Answer:Lumia 1520 capacitive buttons do not light up after Cyan update

You can fix this by going to settings-> Display-> Turn off battery saver brightness.
Hope it works for you

Answer:Satellite A300-15K: How to turn off lights in media buttons


Please check the BIOS settings? I?m not quite sure how the option is called but search for the ?Illumination LED? and set it to ?disabled?. You should find it somewhere in the ?Advanced? tab.

Do you know how to access the BIOS???

Press the F2 button immediately after notebook was powered up.

I love my Lumia 520, but it's a frustrating phone to use at the moment. Sometimes when I want to go back to a previous screen, the BACK/HOME/SEARCH buttons go dead, and sometimes it's like the calibration of the screen is out. In using the keyboard for example I will press "A" and the phone will type "U" instead.
I noticed however, that they work perfectly fine when I remove the cover and use the phone. Am I the only one experiencing this, and is there a fix?

Answer:capacitive buttons on lumia 520 don't always work

Maybe the digitalizer (The part of the screen that register the touch) connector is faulty or is not making a proper contact with the phone board. Have you try using another cover? Maybe your current cover is making too much pressure and the digitalizer don't work properly.
If you have some very basic skills in disassembly stuff, you can clean the digitalizer connector with alcohol and hope that solves the problem. You can find many tutorials about L520 disassembly.
Another possibility is that your L520 digitalizer is just faulty and needs replacement, good news is that part should pretty cheap and there is a lot of tutorials en YouTube about how to replace the L520 digitalizer. Good luck.

Hi, can you help me with my stupid problem? I have 2 questions: 1) Is there a way to enable trackpoint to work with the capacitive layer? I.e. to be able to use it without physically pushing the pad down. Now, as soon as I touch the trackponit, it disables light clicks (touches) of the touchpad, I guess to prevent unintended palm clicks 2) Is there anything I can do to make the buttons work again? (See the story below.) I have cleaned it all even inside, but there were almost no stains at all anyway, none on chips or cables. And it partially worked just this morning.I guess I could soak it in water, then ethanol, and finally dig into rice grains for a week or two as a last resort...but I hope for a more electronics-friendly solution. Story:I spilled my coffee into the keyboard and touchpad, and even though almost no water got onto the motherboard (a few drops), I cut off the power supply in less than 10 seconds, and I cleaned it all thoroughly (even managed to get inside the touchpad itself and assemble it all back...what a pain), it works weird.At first, it registered about 1/10 or 1/20 of physical button presses (depressions of the pad). So technically it somewhat worked. The capacitive (touch) layer worked fine including multitouch. Then I tried to just click on it repeatedly for about 100 times rapidly, and it started to miraculously work 100% fine...for about 30 minutes, then it returned to the 1/20 state again.

I have a bit of a strange issue with my computer. Forgive me if I'm a little too descriptive, but I'm not sure which details are relevant and which are not for such a problem. First, the specs:

Model: eMachines T2984
Operating System: Windows XP Service Pack 2
Processor: Intel Celeron D Processor 340, 2.93 GHZ, 256K L2 Cache, 533 MHZ FSB
Power Supply Unit: Bestec Model: ATX-250-12E REV: P7
Motherboard: I can't tell, but it appears to be an Intel motherboard by the number of Intel labels on it
RAM: 512 MB DDR SD originally, added 1 GB a couple of months ago
Let me know if you need anything else...

Yesterday, I got home from shopping around 1PM, and I tried to start the computer. I pushed the power button, and nothing happened. I checked all of the cords, and they were all plugged in. Not knowing what else to do, I opened up the case to see if there was something obviously wrong. The only thing that I noticed (other than a bunch of dust) was that the power supply unit was still hot. I shut the computer down about 5 hours earlier after about 20 minutes of use, so it seemed strange that the power supply was still hot. I unplugged the computer just in case there was some sort of fire hazard.

At this point, I called a friend who suggested that the problem might be with the motherboard or the power supply unit.

A few hours later, I plugged it back in to try to get it to work. As soon as I plugged it in, the entire unit suddenly started "running" by itsel... Read more

Answer:Computer Doesn't Turn on, Fans and Some Lights Turn on Automatically

I would suspect that the Power Supply Unit (PSU) is going south. If you have a spare one laying around, install it and see if the problem goes away.
You can buy a new,better PSU from Newegg for about $40.00. I have used a Thermaltake 430 watt in one of my machines for some time now and it works well.
You will have to check the size of your PSU to be sure a new one will fit into the eMachine.
Here's the page with that PSU on it. It's the last one on the list.

I can't turn my computer on. The fans and lights turn on for a second and then turn off. a few seconds later they'll turn back on and then turn back off. I've had this computer for 4+ months now, i built it myself. it recently started doing this but i'd just turn off the PSU (Power Supply Unit) and turn it back on and it woould fix it. now it doesnt fix it anymore. i've re-slotted the RAM (Random Access Memory) and pushed it in firmly, but that hasn't done anything. i've tried different power outlets and pushed everything into the MOBO (Motherboard), i havent messed around with CPU (Processor) because that's just a pain in the a**... i was wondering if there was anything else i could do before having to take it into a local repair shop, lol.

as for my computer specs

CPU (Processor): Fx-6300 AMD
GPU: R9-270x AMD
RAM (Random Access Memory): 8GB Ballistix sport
MOBO (Motherboard): ASRock 970 Extreme3 R2.0
PSU (Power Supply Unit): Corsair X500 w 80+
Case: Rosewill GALAXY


Answer:Fans turn on, lights blink and then turn off/on repeatedly.

First, I would unplug everything that isn't necessary. Everything external except for the keyboard and monitor. Internally, just leave the CPU, RAM and video card installed. See if it turns on. If not, you might try and test the power button. Disconnect the power button from the mobo. If the pin headers allow for it, use the reset button as the power button. If not, you can use a flat head screwdriver to power on the computer (cross the two pins for the power button with the blade of the screwdriver). If you do this, just be very careful. Touch only the power button pins and nothing else! You could easily damage components by touching the screwdriver to the wrong thing.

Some motherboards have a power button right on the board that you can press to power on the computer. I looked at a pic of your board and didn't notice one.

If that doesn't do it, plug the power button back in. You might try and play around with the RAM. I don't know if you have 2 or 4 sticks of RAM, but try and boot the computer with only one stick of RAM at a time. If there's a bad stick, you'll find it through this process of elimination.

If none of the above works, then it might be a bad PSU.

You can try a new  RAM stick.What you describe can be: Anything overloads the PSU, or a failing PSU Bad memory in the low region. BIOS  can't run without it. Bad CPU, or heat sink not in placeDisconnect the HDD and the DVD drive. (Power off, of course.)Power on. Does it  show the  BIOS?

Hi All,
I am using the phone for past 10 months and updated my lumia 720 to cyan from black 2 weeks back with windows 8.1 update. After 3-4 days the capacitive touch buttons start to work automatically and only way to stop it is lock the phone. It only happens at random point and dont know how to bring it up again.
I walked into Nokia Care twice where the phone worked without any hitch and I tried as much as I can to bring it up in front of them, but I couldn't. They ran the full test in system and said the phone is alright and I can continue using it.
But as soon as I reached home it started again and went next time, again phone was behaving properly and they gave it back. Today it started in the morning itself. Any idea what triggers it and how to bring it up to show Nokia Care.
Thanks & Regards,

Answer:Dell Inspiron 15R won't turn on ! No lights will turn on .

Hi PARTH511722,
What is the exact system model?
Are you using an original Dell OEM Adapter? When you plug in the adapter to the system, does the adapter stay firm or does it fall off easily? Is the adapter frayed? Is there any damage on the system? Could you test with another power adapter if possible? Could you try powering on with another battery?
Remove the memory and disconnect the HDD and try powering on the system with adapter only / battery only and check.
Does the adapter led stay on and stable or does it go off when connected to the system?
If the adapter led is stable when connected to the system and there are no signs of power, then the motherboard is suspected faulty.
Also, please click my DELL-username and write me a private conversation with the service tag and your Name for case records.
Let us know if you have any other queries.

As far as I know this functionality is controlled by Backlight.exe and you can find this in
Program Files\Toshiba\TBS\Backlight.exe

Usually this is a part of the VAP (value added package)? so reinstalling this package should help you to get this working again.

You can also assign this exe file again to the button using the tool TOSHIBA Button Support

Someone wrote this in forum:
+When I go in "TOSHIBA Button Support", I only have empty fields with the choice in the bottom to set "TOSHIBA Assist" or "Presentation". The empty fields are "Description", "Option" and "Target Path". There's a "Browse" button to manually select a program, but I've no idea where the "backlight on/off" exe is, if there's one.+

(I'm sorry for double postings) Case of NumbSkull syndrom. I hope I am posting in the right place. I recently bought a used Dell Latitude XT. The biggest issue is the service tag sticker was removed before I purchased it ( I didnt know this). When I try to boot up I get flashing lights at F4,F5, and the Cap Lock buttons. This will stay flashing with the fan shutting off after about 2 minutes. After the fan is off and I leave the unit plugged in and with the battery installed the lights will turn to solidly lit after about 2o-25 minutes. I can not access the Bios F2 or any other of the F buttons. This unit was orgianly sold with the Vista OS system. The seller installed Windows 7 Professional on it. I have tried unsuccessfully to get help from Dell. With out Service Tag Number they give me a line of *stuffing* that they cant help me without that number.

Okay. I've been having some problems with my laptop for a while now. I had a nice little line of broken pixels going down my screen. The thing was overheating. And it was going really slow. But, it wasn't anything major. It still worked.
Now, the thing won't even turn on. Wait, no, correction, the light for the power button turns on and that's it. My boyfriend just sat and listened to it and nothing else is running.
At first, I figured it was the screen, since it had been giving me problems for a while, but since my boyfriend's laptop went dead and is doing the exact same thing that mine is, I think it's something different. I think it's the motherboard.
Here's why:
Like I said, my boyfriend's laptop went dead too. So, his dad took it to Geek Squad and they determined it was the motherboard. So, now I'm fairly certain that's what mine is too.
So, my main question is, is there any way to fix it? Does it even sound like that's what the problem is? I'm not that computer literate, but I know enough to know that the motherboard dying isn't good. I'd just like some answers.

hi Huff,
Welcome to Lenovo Community Forums!
 You can check this manual on how to Open the computer up and have access to the parts
    You can check if the DC jack recieves power by using your tester. and see if it can direct power to the motherboard.
It is possible that the DC jack is damaged thats why it does not give power to the Mother board

I turned off my system and went out for a few errands. I come back it not turning on, so I thought I had to plug it in. I plug it in and the LED won't turn on, which means it's not charging. I tried my sister's adapter (Toshiba as well), and no luck. I couldn't find any reset hole on the back. It has an internal battery. I didn't get a chance to backup my files. I don't know how to remove the back cover to access everything. Is this a hardware failure? Will I be able to recover my data from the hard drive? Since this is an ultrabook, I think, is it connected to the motherboard? Am I screwed here? What should I do? Any help is greatly appreciated.

Answer:Laptop won't turn on at all, no LED lights or anything

I was playing Sim City, with my power cord plugged in.  Suddenly, a window popped up very briefly that said my computer didn't have enough memory, and then the screen went black.  Then the power light and the red lights behind the keyboard started to flash periodically, like one flash-burst every five seconds.   I tried turning the power off, but everything continued flashing in the same way.  I tried unplugging the computer, and that had no effect.  I made sure the connections on the cord were okay, and they were normal (also, I remember that the icon showed it was charging while it was still on).  I tried taking the battery out and waiting 60 seconds and putting it back in, but that also had no effect.   What should I do?

HP all in one PC, model 200-5000 wont turn on. The green light on the back right above where the power supply plugs in is on, solid green. The little blue light on the front, right next to the power button is flashing along with the light on the side (HDD indicator) and one of the lights on the dvd drive. Press the power button and nothing happens. The power supply is putting out 19.5 volts.I have already tried the holding the power button down every which way tricks and none of them worked. I suspect all of the blinking lights are a clue or code of some sort. Any ideas??

Answer:HP all in one 200 PC wont turn on/ Lights flashing

The lights were all flashing at the same time. I removed the hard drive and CD drive and the lights would still flash when i plugged it in. I then removed the memory and as soon as i plugged it in it started beeping (like it should)  I then put the hard drive and one memory chip back in and it started up. Put the other chip in and it started up. Put it all back together and it seems to be working fine. I ran the diagnostics and it all passed.  Hard to explain what was wrong. I previously had tried reseating the memory and it did not work. When i plugged it in after removing the memory it seemed to wake it up.

Hi,My original problem was my computer randomly shutting down without any error messages or anything like that, as well as not being able to turn it back on until after a while, seems like the longer I leave it turned off, the more time I get to leave it turned on before automatically turning off. Anyways so I decided to open up my computer and take out the heatsink and everything else out, and clean the dust off. After fully dusting off the computer I plugged everything back in and now the fans, and lights turn on, and the power supply fan slowly spins before finally spinning after a while. I get no display or any usb mouse light. I tried taking out the CMOS battery and then putting it back in, Also I get no beep when I take out the ram. I tried taking out the video card and plugging VGA unto motherboard. Also the hardrive, it spins so dont think its a hard drive issue. When I took out the cpu it broke the thermal paste off, so I was wondering if that has to do with anything?Also I am thinking if it might be the power supply and me needing more then 500 watts. My Computer Specs:Assus M3N78-VMOCZ StealthXStream 500 watts P/SOCZ 2x2gb DDR2 RamAMD Phenom x4 9600Evga gtx 460 768 mbLg DVD DriveWestern Digital 1tb Black EditionNZXT Guardian 921 casePlease Help!Thanks.

Answer:No Display-Fans and lights turn on

A quick read of your post indicates that you did NOT damage the power supply. You did something when you removed the heat sink. Check your work, but before you do anything, get some thermal paste. It does not cost much and is required when you take off the heat sink.

I have a Toshiba Satellite (about 2 years old) and for the life of me, I can't figure out what' s going on.

Here's what I do know:

I used a multimeter to test the voltage of the power port on the connector that plugs into the motherboard. I'm getting 19volts which is what it's supposed to be at.

I have replaced the bios battery - nothing

I have held down the power for 60 seconds with it unplugged - nothing

I've tried running on a/c power only - nothing

Possibly the most confusing thing - I was fiddling with the network adapter (the internal pci one - not the usb kind) because after tearing it apart and putting it back together so many times I was trying literally everything - I switched out the network card. (I realize what little sense this makes) but it turned on. For only about 15-20 seconds but it turned on. 3 times. Then died before it ever fully loaded windows.

I assume there is something on the motherboard around the network card area that I touched that made this happen. But I can't for the life of me figure out what. It has been dead as a doornail for months. And something happened when I touched and swapped out the network card.

*total confusion*

Answer:Laptop won't turn on, no lights, no fans.

Does a charging light illuminate when you plug in the power brick to show it's providing power to charge the battery?I
If you wiggle the connector from the power brick to the laptop, does the charging light flicker?

Have you attempted to see if it boots up without the wireless card?

I have a Toshiba P50-A that I took apart to dust off the cooler and replace the thermal paste on. Now there's no lights turning on on it, even when plugged in, and it does nothing when the power button is pressed.
Things I've tried:

1. Reseating RAM
2. Taking out battery and power and holding down power button for 2 minutes, then reconnecting power and trying to boot.
Any ideas?

Answer:No Lights on Laptop and Doesn't Turn On

Are you sure when you were working on the machine that you didn't unplug any internal cabling inadvertently? It's definitely worth re-opening the case and taking a look.

My computer recently refused to turn on. It had been working perfectly the evening before. I could not smell anything burning or hear anything irregular.

On the advice of Corsair, I bridged a green and black wire on the PSU's 24-pin connector to test whether it was at fault. Upon turning the PSU on with the two wires bridged, the fan began to rotate. So either this is not to blame, or the PSU only partially functions.

I cannot figure out what component is at fault, and replacing parts would be quite an expensive guessing game. The Corsair PSU has a 5 year warranty; however, they require me to mail it to California. Being in Australia, this is quite inconvenient and I would rather fork out for a new one. My motherboard, I assume, is out of warranty.

My specifications are as follows:
Gigabyte P35-DS3P Motherboard
Corsair HX-620 PSU
4xCorsair DDR2 6400C4 (4Gb)
Gigabyte 8800GTS 512Mb (G92)
Antec P182 Tower
Intel E6750 Core2Duo 2.66Ghz
Asus 1814BL 18xDVD+-RW IDE
Western Digital 320G SATAII 7200 rpm HDD(Primary)

I recently had to take my computer in to be fixed only to find out my GPU was fried but the guy there was going to way overcharge me to install a new GPU so I decided to do it myself as I have done so before. So I got a new video card, I installed it, I clicked the power button and the cpu fan spins for half a second and then nothing. I called the computer guy and he said when he had it there it was working fine with other video cards and would start up fine. So now I don't want to pay him yet again to try to figure out why it won't even turn on. I've try reseating the memory, reseating the GPU. The lights on the motherboard and the lights for the power inputs to my GPU are on and yet it still won't start. I don't know what to do next. I hope one of you fine people here can help

My X200 was recently working fine, no hints of any coming problems. However, I recently returned home and was disappointed to find my laptop will not turn on anymore. When plugged in, no charging/battery indicator lights come on, and the power button elicits no response no matter how hard/repeatedly pressed. Does this sound like my power source is shot? Is it repairable? I will be replacing the power cord to ensure it's not that, however I doubt that's the problem as I should have had some battery charge to use even if the cord was faulty.

This button is in both a stupid location and stupid design. 
Why would you put a capacitive sesnsing button on the benzel of the screen where people constantly have to touch with their wrist or forearm when using it in tablet mode?
Seriously Lenovo? Even the stupidest people know not to put capacitive buttons near areas where there might be a lot of skin contact.
If Lenovo made guns, they would remove triggers and replace it with capacitive buttons so that people can fire guns accidentally.
Now I have put a sticker over it for the time being to avoid pressing it by accident. 
Is there for me to disable the button in Windows 7 or through regedit?

First of all you have to ensure that latest BIOS is installed.
If you are using the latest BIOS then try this:

Please remove the battery and disconnect AC adaptor.
Then wait some time? two, three hours.
Then plug battery and AC adaptor again.

Check the BIOS settings (set it to default)
After that try to enable or disable the illumination again?

Hi all,

I am having problems with the Ethernet Adapter of my Toshiba Equium M50 236. The closest match I could find on Toshiba's website is the Equium M50 216 (PSM57E). Apart from RAM and HDD size differences the products seem to be the same.

My problem is, the network driver from the original disc won't install properly after I reformatted the system with Windows XP Professional SP3. I installed the drivers with the original disc according to the sequence provided. (With a restart whenever prompted).

However, when I reached the Network Driver, the package installer opened a command prompt and after a while popped up an error, "- Driver was NOT updated! (INF file may be wrong or invalid)" and then an error window with a title "TDevconEx" saying installation failed.

The network adapter section in the device manager lists 1394 net adapter and the wireless adapter only. The network adapter port has both lights on without any cable plugged.

After this, I downloaded the latest driver from TOSHIBA for the 216 (PSM57E) which happened to be the same package included in the original driver CD and it came up with the same error. I opened the INF file and noticed that the adapter is "Marvell Yukon Ethernet Controller".

I've have had a Lenovo g500s running windows 8.1 for almost a year and never had an major issue. But recently I have found that it will not turn on. I have found that by taking out and putting the battery back in will rarely result in the battery light blinking in red. If i try to turn it on at this point it will turn for a few second "prepare for automatic repairs" and then in a few seconds turn back off its original turned off state. I have tried "Flee-Power" while calling technical support and it made a small noise and then issued a burning smell. It's 1 year warranty is still valid. If anyone has any suggestions, a fix, direction, or advice please respond.

I used it two days ago, on battery. Closed the lid, plugged it in, and went to sleep (both of us). Today, it would not power on, no lights light up and no fan sounds, etc happen. I tried holding down the power button for the static discharge trick, and even tried pressing the one-key recovery button (repeatedly). Nothing. Won't turn on even with another (new) charging cable and brick, with or without battery in it.  My laptop is literally half a month out of warranty - I purchased it August last year; it's actually the special Best Buy model, but similar to the other lettered models it seems (especially the Z580).  Called support, they want me to pay them to fix it, and then when I said no to that, hung up on me mid-conversation. And you know what, this isn't even the first time this laptop had problems - I had to call support when I first got it, and they apparently never made a ticket or note of that, so now my laptop has "no history" of having problems. And FYI, whoever it was that took my call that other time, the plastic housing still makes the crackling noise when I move the screen up/down, it never settled. I believe I also had a little power-on issue at the beginning, forgot the specifics, but it was fixed then, or so I thought - again, somehow no ticket was ever created.... (Then again, this new rep thought I had two Lenovo laptops on my profile, so who knows what happened?)Anyone having similar problems with their Ideapads? Know how to fix i... Read more

Answer:P580 won't turn on. Nothing lights up. Not a power issue.

hi Amyx231,
Having No POST, No Power might mean that the motherboard or the DC-IN cable that connects the charging port into the motherboard might have gone defective. This scenarios usually requires you to send the unit in for service and it should be covered under the warranty.
If I may ask, is this the number that you dialed?

Answer:PLEASE HELP, computer won't turn on, fans come on and lights blink

Have you checked that your fans are spinning up? Is the heatsink sitting flush with the CPU? Have you made any changes to your hardware on the mobo?

Notebook fails to turn all the way on when power button is pressed. Caps Lock light and power light turn on for a few seconds then power off without any actions occurring on screen (screen remains blank and black with no changes). Hard drive light also turns on and goes off a few seconds later but is orange colored (not sure if this is typical for these laptops). This computer is brand new and has never been turned on. I have attempted a hard reset but had no success.

Was troubleshooting a computer that won't start

Computer worked perfectly fine, underwent an update, and inexplicably crashed. Trying to turn it on won't so much as hint at a flicker of any light whatsoever on a motherboard, or screen, or even make a sound from a fan, or turn a fan on, etc. Absolutely dead.

Tried a brand new PSU to no avail. Disconnected previous one, and connected new one exactly as the previous one had been connected. Flipped the switch in the back of the new PSU to 'On', and tried the 'On' button on the case. No peripherals were attached whatsoever at any time. No joy.

Under these circumstances, would the problem most likely lie in a tossed-out motherboard, or CPU, and why? I imagine these could be the only two culprits, unless a bad CPU fan could be a candidate? A fun note: this is a refurbished computer (I wonder why those are a bad idea?)

*Added* It was the windows 8.1 update that the crash happened under (but not necessarily caused by), and the computer is a Gateway DX4870 that had 8 installed already. This should be it: - Refurbished: Gateway DX Series DX4870-UB2B (DT.GEEAA.002) Desktop PC Intel Core i3 3240 (3.40GHz) 6GB DDR3 1TB HDD Capacity Windows 8 64-Bit

Thanks for any help!

------------------------------------------------------------------------------------------------MODEL : TOSHIBA SATELLITE C640D

I have a problem with myToshiba Satellite c640d. It wont turn on, but the Power LED Indicator is on! When I press the power switch, it starts for only a second or less before turning off again(when it starts to turn off,the LED also turns of as well, before lighting up again). Ive tried so many solutions, including the discharging method, replacing and testing several RAMS and checking the HDD's status, even replacing the CMOS battery. Everything is perfectly fine. I checked the processor's core, everything seems to be fine. The thermal paste is still in working state (still not dried up). I got it working again with luck a few times though, and its random, but it only turns on for 5 seconds(it made to the boot screen) and after that it shows a system error, something about a problem with CMOS. But the thing is, the battery is still new. And I bought 3 batteries!(and even tested with each and every one of them) If my laptop made it that far(sometimes i got through til the log on screen and actually logged in my user before it starts powering off suddenly!), then I'd say its not the motherboard, not the processor, not the CMOS(maybe it is but still its new!!) not the HDD and not the RAM, and most certainly not the scre...

I have a Nokia Lumia 635 and have updated to windows 10 anniversary. The app control buttons are now masked by the three system control buttons at the bottom of the screen, so you can't use the delete, sync etc buttons.
In messaging the pop-up keyboard masks the typing line so you cannot see what you are typing in portrait mode.
When using the BBC News apps the text is rendered in a huge font which makes the app unusable.

Answer:Why can't I see the app control buttons after latest windows 10 update?

Hey guys,

I have an ASUS t300la currently running windows 8.1.

I have a recurring problem with my Capacitive windows logo button, on the bottom of the bezel (not the keyboard or on the screen).

The problem is that it intermittently stops working. No haptic feedback and no response. Sometimes it will start working again if I restart the computer. Additionally, i can press the button during startup and the haptic feedback will occur as much as i press the button (no function though, obviously).

sometimes, even if i restart, it will not work. However if this ends up happening, it would still always give the haptic response during startup, and then would stop working when the log on screen appears.

I have done a lot of research but to no solution

My windows is fully updated as of 9/29/14, and my drivers SAY they are all updated (although i do not always trust the automatic search for driver updates).

since this is very intermittent, i believe it must be software related, so forgive me if you believe this is posted in the wrong section.

Any thoughts or suggestions?? As i have said, i have done lots of searching and tried many options..but i have still not found a problem similar to mine.
PS. I get a consistent Event ID number which I feel may be related. However, sadly, I have not been able to find much info on that either.
The Event ID is #264 and states that "A multi-touch device reported inconsistent contact information."

I am not certain it is related,... Read more

Answer:my laptop continuously beeps when i turn it on lights show a

Impossible to diagnose accurately without knowing the BIOS maker and the length and pattern of the beeps, but classic causes are failed RAM or faulty graphics adapter, so there's two things you can investigate.You can test the RAM with memtest86: only way to check for failed graphics adapter is to swap it out with one that you know isn't faulty (there is no need to install the manufacturer's driver just for testing purposes).If the problem persists & you need to post for further help, please say what you've tried so far to to fix it. Giving you the same advice twice & just going round in circles will then be avoided.

Hi, I would firstly like to apologize for not being able to update my user CP or tell you what my CPU/Mobo is. I can't get my computer to turn on and can't access the info.

This happened while I was trying to reset everything on my computer (because there was a problem with my NIC). I unplugged everything and replugged them into their respective places, and now I can't seem to turn my computer on. Everything was working fine (except the NIC) prior to my resetting. Now the problem is when I turn on the power, there would be a small delay before it would turn on, and when it does turn on, the lights in front of the computer (for the on switch) flash, the flashing intervals are synchronized with the rate the CPU fan turns on and off. The case fan is running constantly however and it is blowing out cool air. I have done some searching on the forums, and I have heard that it was because I unplugged the 12-20 wire that connects the power button (in the front) to the CPU. I unplugged this wire and the fans still turn on and off, except the front LED's can't flash. If anyone can help me, that would be most appreciated.

Answer:Lights flash, fans turn on and off, comp remains off.

You gotta do some more diagnostics.
But before I'll start listing them, I have one question:
Before you've removed components from your computer did you un-plug it from AC outlet? Cause if you didn't you may've damaged motherboard or any other component for that matter. I know it sounds silly but I'm just making sure.
Anyway, do as follows:
Unplug the power. Open the case and re-sit you memory modules and if you have to re-sit your CPU chip. Re-sit all your add-on cards (sound, video etc.) Make sure you re-install the CPU heatsink properly. Make sure that all cards and modules are snug and properly sitted in the motherboard.
Note! Dont' ever operate your CPU without properly installed heatsink, ever!
Plug it back in and the try to boot. If it's still no go:
Unplug it. Pull all the cards out except for the video card. Disconnect all your drives: hard drives, cd/dvd-rom/rw drives, floppy drive(s) etc. Actually disconnect everything from you motherboard except for: CPU, 1 memory module and video card (and of course power supply - make sure the 12V+ cpu plug is in the motherboard!). Plug in and power on. See what happens. If it's still no go move the memory module to a different slot; power on; still no go - pull the video card out: plug-in power on; still no go:
- Your power supply, motherboard, memory module or CPU has gone bad - you gotta swap them out with differnt component to test if this fixes the problem; star... Read more
