Laptop LCD goes partially black. Help


Something really wierd and scary happened last night to my laptop's LCD screen. I woke up to find the righthand bottom corner electronically stained with what appared to be black dissolve. There was nothing physically on the screen but it looked like someone had smeared black tar or ink on my computer screen.


Luckily, tapping the screen with my fingers caused the darkness to gradually disapate (now it's all gone), but I'm still left wondering what the hell happened. Is this a serious issue with my LCD? Does it need to be replaced? The computer is only 1.5years old.


Other points to mention about the laptop:

I do keep it on a lot (mostly for downloading)

It has a loud (hot) fan which causes some overheating, and in order to keep the noise down (because I stay with many people), I sometimes close the laptop and cover the computer with as pillow or a blanket. It reducez the fan noise and I make to sure to always leave a pathway for the hot air to escape.


I've been doing this for a while now, and the blackness only appeared last night.


What is the blackness? What caused it? How can I avoid seeing it again? Also, if it does have to do with the overheating caused by the computer's fan (what can I do to keep the noise down without causing such a disruption with the LCD)?

I have certain disquieting thoughts on why that would happen - but I will keep them to myself. But I would do a bit of on-line research, and I would ask around for information on the feasibility of local repairs to your computer's lcd.


The fan keeps the computer less hot (not makes it hot). Closing the cover and covering it with a pillow, even with a snorkle (you need air coming in as well as air going out) stikes me as a good way to cook a computer.


Why you feel the need to keep the machine running 24/7 is your business, but computer abuse is computer abuse ;^)


Good luck!

Laptops get very hot. My old compaq got even hotter if I closed the lid.


Sounds like you may be cooking your screen.


To aid cooling I used to put a book under each end so the air could circulate better underneath (where it got hottest). You could also try putting a room fan on it (if you have a quiet one) so the computer fan is not overworking.
