Today my screen started flickering fast, I shut off PC, turned on and it kept flickering.

I turned off the PC again, removed the AC adapter and it'll start up fine, but if I plug in the adapter it makes a weird whisper type sound and it starts to flicker again. The 'charging' light is also a solid orange.

Anyone know what the problem is?


Edit: Orange light is gone, but the problem continues. And if I take the AC adapter out, the battery light flashes green every so often like it always has.

If you take the battery out, will it start up correctly on AC power?
Not sure, I did a system restore and the blinking is gone. Anyone know why that could be?

power cord may be faulty or its not the correct one for the machine
It's worked for the past year, so it's not the wrong one, but i'll see if I get my hands on another cord.

I agree with Bernardo, don't be tempted to buy the cheapo ones, so many posts here tell tales of damaged computers due to sub standard power cords.

It started happening again..

If I take the battery out and use AC to power on and it works, should I keep battery out?

Edit: It seems without battery, nothing will happen after booting up.

hiya pal,unplug from mains,take out the battery and carefully clean the connections,use a common eraser,put the battery back in and it is advisable to flatten it out occasionally,( drain),charge up fully and don't keep the cable in all the time.

I think something may be wrong with my screen actually.

After turning it on, the screen goes black nearly instantly, but OS is still going ( can hear the noises ).

Could it have something to do with the battery, and how can I fix it?


Plugged in an external monitor and it's black on that even. Video card problem i'm assuming?

I'd be thinking video card too.
Heh, my bad. I forgot to use the FN+Alt4 to change the screen to external. Well, it worked on external.

So now i'm back to step 1...what could the problem be?!

The screen goes black before it gets to the Windows screen.

The backlight on the LCD screen.
Alright, and to make sure this could be what the problem is..

Would a AC adapter being plugged in and removed have an effect on it?

Also, it makes almost a 'Tzzt' sound before it goes out, and the display is red.

Edit: Yep, definetly the backlight. Used a flashlight on the screen, can barely see what's going on. Greaaat..

From what I understand, if you have any tear apart skills at all, they are not at all hard to replace, and easily found on eBay :)
