    Actually the screen saver is set for 10 minutes. I have the same problem whether the screen saver is on or not. Moving the mouse does not change the black screen. Thanks.

O n most dell laptops right at the base of the screen is a panel that pops off. If so there is a small card about 1-2inches wide ans 3-4 inches long. It is above the keyboard. this is an aux. power board and should have a connection on it to help power the screen. If this model dosent have this poard than the built in screen cooler is bad and you will have to replace the whole screen.

My acer asipre 4739z laptop starting after a few minutes not work. fan is running battery is ok


Please describe a list of events that takes place from the time the ON button is pressed until the screen goes OFF. Attach an external monitor and press the Function key with the screen key to transfer video. If monitor responds the video is OK but screen is BAD. Then replace Screen. If Monitor does not show video then problem is probably a thermo problem. To correct video chip overheating do the following; First ... Remove Battery. Remove CPU and Video Heatsink and Fan. Clean dust and lint that is blocking airflow in heat transfer grill. Clean dust from inside fan. Clean old heatsink grease from Heatsink and from Video chip and CPU. Apply fresh High Quality Heatsink grease evenly but sparingly to chips. Replace Heatsink following tightening order to spring screws at CPU. Replace covers ... and start.

Dell inspiron 8500 laptop screen goes white


hello, when the screen changes colors or stays in one color it is mostly cause of a video card problem. Does this happens only when overheated, then maybe you can blow the cpu-video card heatsink and use a base with a fan to avoid overheating. If the screen is white all the time then maybe only a 2nd monitor will help understand if this is a problem of the video card or the screen.

Laptop turns off after being on for awhile--especially when running a video. When starting back up, has to reboot and resume Windows.


Hi there,

Try running dxdiag. If you are using XP, click start>run then type dxdiag. Click the display tab then run the tests. If your pc fails the test it is a video card problem. You can try updating the video card driver. If if is still under warranty call the manufacturer and let them walk you through the BIOS firmware update. It is risky that's why you have to call them. If it still does not work, motherboard or video card must be replaced.

Dell Optiplex GX270 sounds like a jet taking off. What is wrong and what do I need to do to fix it?


Hi,
You have to find out where the noise is coming from. It could be;
1) a fan on your motherboard if it has one
2) the fan on your heatsink that keeps your cpu cool
3) the fan on your power supply unit
4) a cd or dvd rom drive
5) one of your hard drives
6) one or more of your case fans.
7) a fan on your video card if you have one.

You don't want to open your power supply, so if this is the cause of the noise you can replace the whole PSU. Other than that, any other component listed above can be replaced by going to newegg.com for parts.

Good luck,
Hank

Black screen..computer working


Hello Sir,

This is the Dust problem.If the CPU heatsink is not clogged with dust and lint completely, you can use canned air and just blow it inside the laptop through the openings on the bottom and on the sides. It’s nice as a precaution measure, but it might not work if your laptop already has a problem and the heatsink is completely clogged.
  1. Open the laptop case, so you can access the CPU fan and the heatsink. In some cases you can access the heatsink through the latch on the bottom of the laptop. Sometimes (for example Toshiba Satellite A70/A75) you have to open the laptop case all the way down.
  2. Carefully disconnect the fan cables on the system board and remove the fan. If the fan makes unusual sound when it spins (grinding sound), I would recommend to replace the fan.
  3. Clean the fan and the heatsink with compressed air.
  4. I would also recommend removing old thermal grease from the CPU and applying new grease for better heat conductivity.

VGC-RB50 Display Problem


I hate to be the bearer of bad news, but I think that the MB or the processor just took a dive on you. Most likely the processor... as you are able to power up. If it were the memory or the video card, you would hear a series of beeps when trying to start the computer. And you already verified the monitor is fine.
