Question about Acer Aspire 5100 Notebook

1 Answer

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?

I have x2Gen 19" LCD Monitor. I hooked up the
More likely to be the fuse for the backlight inverter circuits rated at 3.5 or 4Amps. It is PICO fuse.
The transistors that drive the inverter transformers may have been damaged, should check them out before installin a new fuse. In the mean time you can use 1 to 2 Ohms 1/2 Metal Oxide (MOX) resistor in place of the fuse, if the resistor overheatand open up then you have shorts circuits.

I just got a used syncmaster 203b monitor. I hooked it up and all I get is a black screen. I downloaded Driver whiz and hooked it up again. Still a black screen. Still get a black screen the blue light is...
Make sure that your computer unit is working. Sometimes we suspect that it is a monitor problem but usually, it is a frozen CPU set.

When you turn on the monitor, it should light the blue led and after a while, when it does not receive signal from the CPU, it will turn orange. If that is the case, the monitor is functioning well.

So what could be the problem?

Make sure that you hooked the monitor to the right VGA port. If you have an internal VGA port (built in with the motherboard) and you also have an external Video Card, you should hook it to the external VGA port and not the internal one since it is overridden by default.

Do you hear the "short beep" sound when you boot your PC? That signals a good video system. If you don't hear that beep sound (provided your PC's speakers are okay), you should open your CPU case and try to remove your memory modules (RAM). Clean the pins with an eraser and put it on.

Now, your computer should work fine and so with your monitor.

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 www.ebay.com

Have you unplugged the power cord to the LCD? Let it sit for a minute, then try it. ALWAYS buy a UPS and plug any computer devices into it. Doesn't have to be big, a $50 unit will protect it from dangerous voltage surges.

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;

ftp://ftp.work.acer-euro.com/notebook/aspire_3680/

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

Thanks

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.

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.
