It's time to consider a repair counter, dell repair or another laptop.
I have a dell studio 1536 laptop , it was dead since last year , i bought another motherboard from e-bay yesterday and installed everything was ok eccept i had to install windows again. I noticed that the dvd rom couldnt read any dvd as it was a previous issue which i tried to resolve by adjusting lens power level and failed as the motherboard died on me , but this time i did the same and i keep the toupad panel removed all the time, start and shud down the laptop couple of times and realised the dvd and hdd makes noise and nothing comes on display , i reassemble everything and did everything , reseting memory , removed cmos, swaping rams , AC in-out w/wo battery , changed heasink with fan as i had one , with no sign of display . i am so frastuated as this is the second time with this laptop and board is getting problem ,
keep in mind that aprt from swinging hdd and noise of dvd rom i dont see any other activity as laptop shuts down automaticaly after 9 (9 seconds) light flashes as i see in touch panel speaker button flashes ,
last time when this problem hapened the board was completly dead but this time it does the above activities .
