My T20 suddenly "died", black screen, 1 diode shining. After a certain time, it can be started again, than is working cca 8min and than dies again. When started again immediately after this, it does not start or does the same after a short time. No beeping on start. Fan assembly looks OK, fan is shortly working on start. This is with W2K, but Linux live CD is the same. According to MobileMeter CPU temp is 39oC, HDD 41oC. Please any suggestion? THX a lot.

Re: T20 black screen crash
This could be a problem with the memory. Try removing the memory and starting & running one chip at a time in both slots one at a time. If it turns out that the memory and slots are good, then this will be a motherboard component. Componenet problems can be tricky to track down, even for veteran professionals, so I suggest taking it in for a professional diagnosis.

If its on a reinstall click repair the first time and it will take you to Recvovery Console and a command prompt and then type fixboot..
that will fix your boot record and you may not have to do a complete reinstall. If it does not work then start reinstall again and just install normally. Please rate this solution.
This is going to be one of three things, 1- bad battery, remove the battery and try starting on the adapter only. 2- bad memory chip or memory slot, remove the memory and try each chip one at a time in each slot, and 3- a failed power management component on the motherboard. If 1 & 2 don't work, then the problem will be with the power management system, which is a common problem with these machines. Unfortunately, motherboard replacement is the only option with a failed power management system.
Laptops are very fragile and sensitive components! If you feel that you are capable of task like this then godspeed!
Something like that could be three things!
1.) Your screen inverter has gone bad! The inverter is the device that provide high voltage power to the lamps in your screen!
2.) The lamps in your screen are bad! These things are usually rated for like 50000 hours.
3.) It could be as simple as servicing the laptop(cleaning up the contacts and ensuring good connection)
Laptops come in all shape and sizes, and worse some come with a thousand screws of different sizes! It should be relatively easy to take down but the hard part is putting it back together. I have this friend who, after he re-assembled a laptop, always has extra screws!! He says the laptop don't need em! LOL
What i would suggest is moving the entire screen, that way you don't have to take it apart to get to the inverter( should be the only other device located in your screen aside from the actual LCD(the lamps are in the LCD) The models sound very similiar but not sure about them either, it the screen looks the same then you can change it!
Practice taking down the t20 first then if it breaks you'll know how NOT to break the t23! lol
I would always recommend getting a pro to handle something like this though, cause is very tedious you have to be real careful!
Best of Luck!
When it turns black take a flashlight and shine it on the bottom of the screen where the start button would be. Look closely and see if you can seen any faint images there. If you do then your backlight is malfunction. That typically is not a self-fix for the typical user.
If you don't see anything can you give us some more information.
- Are any lights flashing just before or after the screen turn black?
- If you restart the computer will it work again?
- Will the screen go black even if you are actively working on the computer?
If its not the backlight let us know the answer to these questions and we'll continue. As always please don't forget to rate this posting.
