The screen flickers abruptly. And the screen gets garbled as well. But it seems to have really been knocked out today. The temperatures were looking fine at 60C but on a reboot the screen has like six small screen showing up instead of one with the HP logo.
Is my GPU dead? If so what are my options now?
Currently whenever I startup my laptop the display flickers. If windows fully boots or I try to enter one of the startup menus the will flash briefly on the screen and then the display will return to and remain black.
I am able to run an HDMI cable to my TV and it seems to be running fine other than going black with the occasional distorted picture of windows booting.
my laptop screen backlight goes off, when I rest my hand on the left side of the touchpad. The darkening of the screen can be also reproduced when a small pressure is applied on the case just above the ethernet port or above the headphones port.
When the screen goes dark, I can see that everything is running normal, if I shine on it with a lamp or strong light. The resulting effect seems to be the same as if I would have lowered the brightness to minimum.
When I don't press the area described above, the screen is just fine. I am sure this problem is not software or OS related. I googled it a lot and my guess is lose connection on the inverter?
One last thing - idk if related - sometimes, when I boot up the laptop, the backlight is turned off and I have to adjust it by pressing F3.
Model: HP15-N096EA ... When the laptop is turned on the screen colurs are inverted i.e. blue becomes orange, white becomes black etc. at times it flickers back to normal colours i.e blue shows as blue etc.
I have checked magnifers invert colours isn't turned on but when I do turn it on the inverted colours switch to normal colours obviously. There is also a vertical shimmer like every other vertical line is missing or phases in and out.
I have booted into safe mode to see if its a driver issue but the colours are still inverted, I've booted into the BIOS and again the colours are inverted and just to cover all bases I booted a live DVD of Mint Linux 17.1 and the legendary green of the mint distro was a lovely lilac. I've also tried high contrast i.e. Left ALt + left Shift + Print Screen.
My feeling is its the graphic chip or the monitor and I'm hedging more towards the monitor. Tomorrow I'll do a screengrab to see how that comes out and will also connect to an external monitor to see if the flicker and shimmer is still present.
Considering this is literally a month and 6 days out of guarantee it pretty bad, I would have expected a bit longer from a laptop before it started failing.
Update from Yesterday: I did a screengrab from the HP using the snipping tool in windows 7, this showed the colours inverted i.e. negative, I saved that screengrab to a USB stick and opened it up on my Mac, the image showed correctly i.e. not as a negative.
This is the image that is displayed on the laptop, there is no colour inversion, none of the graphics settings appear incorrectly set, I did actually set all settings back to defaults.
This is the screengrab from the laptop as it displays from another computer, which, in my case was my Mac. The screen appears to be displaying correctly, hence the screengrab image below but for some reason it is displaying an inverted image - Its like there is an overlay on the screen.
Could the inverter be faulty?
I purchased my laptop about two years ago. A few days ago, the screen suddenly dies, and on boot, it flickers a few times with the proper display, but then goes blank. The backlight seems to remain on though. When I use an external monitor with the HDMI port, the external monitor works fine, however the laptop screen remains blank. Here's a video of what it looks like when I first boot the laptop: [URL] .....
View 2 Replies View RelatedMy laptop screen flickers and fades out. Why does it happen and how can I recover my system?
Laptop details:
Dell Inspiron 14z 5423
OS - windows 8
I have screen flickering problem with my Acer Aspire 725 with windows 8 OS.
Flickering stops when i remove the power supply. I could see the battery plugged and unplugged symbol in Windows 8 continuously. Whether i should replace my battery or power supply adaptor?
This problem has bothered me since I have installed the windows7 rtm.
i am using integrated graphi card, everytime when the machine wakes up from sleep, and if the external power is unpluged, the screen starts to flicker, and windows 7 reports "displayer driver stopped working and have been recovered", looks like a driver problem, but i have downloaded from the driver from sony website and intel website, none of them solves this problem.
I have a Dell Studio 1745 and there is an issue with the magnetic switch. The issue seems to be that the switch itself can't seem to make its mind up whether it has been activated or not. On boot the screen flickers on and off slowly, placing a magnet near the track pad (where the switch is located) increases the rate of the flickering, however it does not solve the problem. Looking inside the laptop the switch seems to be a soldered chip, is there any way to solve this completely? I've connected it to an external monitor, however the picture will only stay on the screen with the magnet in place, removing the magnet causes the picture to come away from the monitor and back to flickering on the laptop.
View 1 Replies View Relatedwhen I turn on my Z, the screen glitches two or three times upon hitting the login screen. Does this happen for anyone else?
Sometimes, (it's happened once or twice) my graphics card even failed upon logging in and had to be reloaded, and even, on one occassion, completely shut down my computer (Straight to black, green light turned red) in the middle of casual browsing.
Are these causes for concern? Should I return my laptop?
Issue #1
Specifically 15" Late-2008 models (first of the Unibody range) running on the integrated 9400M graphics mode; where the the top 1/3 of the screen blacks out for a few millisecond ever so randomly with no obvious way of reproducing it. Sometimes the whole screen blanks out instead of the top 1/3 part.
Video samples of those that are lucky enough to capture it on film.
I've performed multiple SMC/PRAM resets, fresh system installations with full updates (10.5.8) and they don't seem to go away.
_________________________
Issue #2
Weird graphic glitches on the same machine, best described with the following video and text:
Several observations to reproduce the glitch:
- Happens only on battery mode, regardless of which graphics card (9400M or 9600M GT)
- Happens on a freshly-installed, fully updated, SMC-resetted system with 10.5.8
- Only happens when you scroll very quickly (i.e. using the two-finger scroll on the touchpad) on a long list (refer to next point)
- Drop down list/menu has to be extensively long that requires at least two or three screen's worth of real estate. An example would be the 'Fonts' folder (/Library/Fonts), drop this into the dock as a stack and view it as a list.
- Reported to happen occasionally with the Spotlight search menu.
My work computer will flicker, go blank/black and sometimes I can tap on the battery or the hard drive and it will come back. Sometimes (more times than not) it will require a total reboot. Lately it won't even load. It will load the Dell screen then it says Starting Windows the logo comes on then it goes black. It still loads and everything but I can't see anything. I've replaced the hard drive so I know it's not that. I've loaded the computer in safe mode and I have NO problems with it when it's in safe mode, only when it boots normal. I tried the FN+Power but nothing happened when I tried that the numberlock LED is the only one that stays lit, the others didn't start flashing or anything

Basically my computer is always very hot. Just downloaded SpeedFan and the GPU and both Cores are 78C and i've just been surfing the web for a few hours.
The problem happens when I play games (like Civ4 or Half-life 2) for a few hours or sometimes less if its a hot day. The laptop will abruptly power off as if I pulled the battery and power cord out.
When I reboot, I get that error message that says Windows did not shut down properly, do you want to reboot normally or in safe mode
I have Dell Studio 1555 which is around 4-5 years old. No warranty left. Today while I was chatting with my friend on skype, it turned off abruptly. It was plugged in and was working fine from last few days. However, when it turned off, the screen turned off like the screen of a Television. It is not turning on now. I've tried pushing the power button but nothing comes up. The fan used to make a lot of noise from last few months, when used for a long time. What can be the issue? I've searched on internet and it points towards motherboard problem.

View 3 Replies View Relatedi just found this forum and it seems like you guys could help me answer this question. i have a dv2000 laptop i bought about 2 years ago and the screen has started to mess up. essentially it has two problems.
1. there is always a vertical line about a pixel thick that stays a yellow color. no matter what is on the screen, the line is always yellow. if i bend the display panel a bit it disappears but comes back as soon as i let go.
2. when i open and close the laptop to adjust the screen angle, the screen starts flickering with these white lines. i have to keep messing around with the screen (moving it back and forth) for it to come back to normal. im not sure if a cable is loose or maybe broken.
im assuming that i need to replace the entire display panel but im not sure if i can get away with just buying the lcd screen and replacing it. i can probably get rid of the yellow line on the screen but i think the flickering is caused by something else. could it be a loose cable that i just need to fix?
I have a "compaq presario v6210US" which worked great for a while then it just shut itself off and restarted and the screen stayed black. Now it keeps restarting itself but the screen stays blakc. I can hear the fan and hard drive and everything else running the way it's supposed to. I heard that this has happened to a bunch of other people so it sounds like a defect to me. How do I get it fixed or do I just pull the hard drive, toss the Presario and get a competitors laptop?
View 1 Replies View RelatedI have connected my monitor to an external monitor. It works fine. Only problem I have ( and a little irritating one) is that the external monitor picks up display only after Windows is loaded. Pre-OS screens like BIOS settings, GRUB loader (I have Installed Linux ) doesn't show up)
Is this an issue with BIOS? Because, when I connect HP dv6000 to my monitor, I can see the BIOS screen as well. I am sure the problem is not with the monitor.
The BIOS is responsible for detecting displays before the OS is loaded right? I checked BIOS settings and there is nothing to indicate the display ports/devices (however, this page on HP website shows a BIOS screen "Advanced" which apparently has those settings)
When I replaced my customer's screen on their COmpaq- CQ62-219WM and it showing up black. When I shine a flashlight in it I can see the start menu and whatnot. That means that I need to file a RMA right? I am guessing because the blacklight is out.
View 3 Replies View RelatedI have a Compaq 3000 Laptop, it's almost 2.4 Years old now, over the period of time I dint faced any issues with my Machine.it all started yesterday.
I was watching a movie on my Laptop yesterday, after sometime the screen froze up but the movie was playing as I was able to hear whats going in the movie.
Later I tried restarting the machine, what i get is the machine boots up properly, but the screen doesnt display anything thing, it shows up a blank white screen, sometime when the windows XP loading picture comes up the screen shows light distorted colors but again goes white blank.
I did approached a local vendor for that but he says that we need to replace on the motherboard, I was not much convinced over his explanation over the issue.
I would like to know your views on what might be the problem with my Machine.
I am going to try over connecting an external monitor and see if LCD is the problem, but I would like to know more what all possible options are there which might be affecting my machine and how much would it cost me in the worst possible case.
I have a Compaq Presario CQ60. The Display does not appear to be working. When I turn on the laptop the display remains black. No boot up screen, nothing. I can't go into the bios because I have no screen. The screen remains black. The harddrive appears to be working and all other functions appear to be working but I am not sure because I have no screen.
Is this a known issue with the Compaq Presario CQ60?
I am currently stumped on troubleshooting error code lights for a clients hp compaq cq62. I have tried the hard reset, reseating the memory, and even plugging the notebook directly into the wall instead of a surge protector with the battery removed. I cannot find any solution on the HP site or any other forum site for that matter as to what a solid caps lock light and a solid orange light on the f12 key.
Currently I am thinking the client is might need a new back light for the system or a new cpu.
I have a Compaq Presario CQ61 Product: VM9496Q2X Model: CQ61-319WM, that has a black screen when I power up. The wifi button stays red and the caps lock flashes twice. I believe this indicates a BIOS corruption failure. I have tried resetting by unplugging and removing the battery, and holding the power button for 30 seconds. I have tried the f8 key and the esc repeatedly at power up. I have also tried pressing the windows and B key along with the power key but nothing worked.
View 2 Replies View RelatedToday, I tried connecting an external display to my HP ENVY TouchSmart 15 laptop, via a USB hub, only to discover that using the touch screen points at the corresponding part of the external display rather than the inbuilt one (the displays are being extended).

I'm using the same 64-bit Windows 8 installation and drivers that the computer came with.
for some reason the on screen display meter for my volume when pressing on the keyboard suddenly disappeared, I would like to get this back. I found this thread in the forum URL.... which another was having the same problem I'm having. The only difference is that I'm using HP Pavilion G7 with Windows 7.

View 9 Replies View RelatedI updated the BIOS to 2.26 a while ago and ever since then there's no on-screen indication of caps lock on/off, screen brightness or volume when I change it. Since it seemed to be affected by BIOS, I updated again to 2.27 just now, but the problem persists. I needed to update the Hotkeys Feature Integration by downloading the utility thingy from this page. Probably wasn't a BIOS thing after all.
