Question about Acer Aspire 5100 Notebook

Black Screen after sitting for awhile

Long story short, 1st LCD got broke. Hooked up External Monitor until replacement LCD arrived. Computer was working until all of a sudden after sitting for and hour not being used, The external monitor went black. The battery and power light were still lite and fan on, but no hd sounds. After a Hard power down the computer will not boot up or do anything. Let it sit over night, and it will start and run fine. Let it sit, and it will go black. Repeat. Next day, when it will boot, and it goes through a disk check, the clock and date are wrong. Reset and it runs fine.

Replaced LCD. Everything works fine except, let it sit for some time and it goes black, rinse and repeat.

Acer says, Restore if that doesn't work "reinstall everything".

My question is what is the real problem, Is it a CMOS battery, RAM, Video card, or a hard drive. I figure it is not the LCD since it does this when connected to an external monitor. How do I tell without replaceing all and finding out it is something soddered or on the motherboard?

Might be that the graphics card is overheating.

Toshiba Satellite L455-S5000 monitor blackout but works w an external monitor

This is a tricky situation, any fluid that ends up inside can cause a cascade effect, hours, days, weeks and even months before the full efects are known. You could end up changing the screen and down the road face major failure in the motherboard. Under the circumstances I would consider a laptop replacement.

If the display works fine on external monitor your video circuitry on the motherboard is fine. Since you replaced the inverter brd and you still have the same problem it has to be either the LCD display panel or the LCD I/O cable or the connector on the motherboard that the LCD I/O cable plugs into.

Check the ribbon-cable between the motherboard and the LCD screen. It is not transmitting 100% of the video-information.
Be sure that it is not "crinkled", and that it is tightly connected at each end.

When you start the computer,there is no image display on the screen but the computer boots until you hear coming on and yet no image display.

Use an external monitor to verify that your laptop is booting up. If you get a display on external monitor and not in your built-in LCD, you have 3 possible problem, 1st - bad LCD panel, 2nd - bad inverter, 3rd- bad CFL. In any case, it is easier to just replace the whole LCD assembly. You can find used and cheap ones at

you could have accidently changed to external monitor with Fn +F(the number is 8 on my comp but could be 5 on yours-check keys on top of the keyboard it has a picture rectangle / little TV), anyways to check that attach external monitor to your laptop(must have a VGA cable) if you have a picture on external monitor try Fn + F(depends on what you have on ur keyboard) it should bring you a window with choices to choose laptop LCD or external LCD choose 1st one .
hope that is it.

Lcd screen broke external monitor wont work

Sounds like you resolution is too high or vista doesn't recognise your driver.

Try starting in Safe Mode by powering up your PC and tapping the F8 key until you see a menu. Select Safe Mode from the menu. Once in safe mode change the resolution to 800x600 then restart in normal mode.

If that doesn't work then download and install the correct drivers for your display card here;

Once downloaded, you may need to install it in safe made once again.

Black Screen

The first thing I would do after turning the computer on is check to see if the video output is being directed to the LCD screen. The output can be directed using the Fn key along with the key with the picture of the 2 monitors on the Function keys at the top of the keyboard. Hold down the Fn key and tap the other key once or twice,
Next, hook the computer up to an external monitor. Do the same thing with the Fn key to see if it's the LCD screen.
If the external monitor works, then you haven't correctly hooked up the LCD screen or it's bad.

Black screen

One way to test it is to connect a monitor to the VGA port (make sure to activate the external monitor (Fn+monitor key)
If it does work on the external monitor, I would look at replacing the onboard LCD.
If it doesn't, you are looking at problems with the onbaord video.
