Is it possible to connect the LCD properly but not the backlight? Might it just be the inverter? (It worked fine with the old broken LCD.) It is possible to have “connected it wrong” to where it goes out after 3 seconds?</blockquote> It's possible the replacement LCD screen has defective backlight lamp. You can try installing the old broken screen back in place and see if the backlight still works. If it does work, the new screen has defective backlight. If you have the same problem with the old cracked screen it's possible the inverter failed.]]> In reply to Mugsy.

@ Mugsy,

I just replaced the LCD in my Thinkpad. When I turn it on, I get the IBM logo for about three seconds before the screen goes black. The computer still starts, but no backlight so I can’t see anything.

I was using my compaq presario CQ61 when it suddenly went off. With the manner in which it went off, i thought it was a battery drain. But when subsequent attempts to power the laptop failed after making sure the charger was properly fixed to the power source, i thought the charger had gone bad. I replaced the charger but there was still no response from the computer. No lights at all.
So i took off the battery, plugged the charger and tried to power the laptop. The laptop still didnt respond only i noticed that the small charging light at the point where i insert the charger comes up and then goes off after a few seconds (this happens only when the battery is out).
Any suggestions as to what could be problem? Anyway i can further troubleshoot? I would appreciate your help.
Thanks.
Best regards.
kels.
