MemTest86+ did report a good working RAM chip for at least one pass. I put the laptop down and the timer froze. The timer had jumped to its correct time and the progress bar displayed as expected. I lifted the laptop with my right hand grasping the right side of the keyboard. On one occasion, I noticed the timer had not progressed and the progress bar looked erratic but working. I would look over every few minutes to check up on the program’s progress. The laptop didn’t even recognize it – I expected 512MB but got only 256MB. Thank you for your reply about my Vaio VGN-S150! I discovered one of my RAM chips was bad, indeed.

But it’s not convenient to work with a laptop like tis. If I open it more than 90degree, It works fine. One thing very special, If I open the lid lower or equal 90 degree, It just flash in milisecond and then turns dark. I am sure that my laptop is normally working except the backlight.When this problem happens, I close the lid and my laptop goes to standby mode,after that I open the lid and the screen it lit again, Sometimes I have to close and open several times to get it lit back. Sometimes the screen goes off when playing film or music but the film or music sound is still playing, and I still can see the statement of the film still moving on in a very dim image. I have a Toshiba centrino laptop, it had been serving me 2 for years but now it has a problem with its LCD screen.The screen often goes off and becomes very dark, there isn’t any lighting on the screen, but when I look close to the screen, I can see the GUI display as it is normally working.
