frozenload if u dislike about this thread. just off from the thread my friend. we actually discussing to find solution on interest . i open up this thread to share knowledge. as my basic knowledge of mother board repair we need to understand smd technique such as reball ic,replace cap ,resistor,power ic and fuse using rework station but reason why im open up this thread to see geeks at toms hardware knowledge. we in asian had successfully fixed most of laptop motherboard. If you just replace mobo to new set of mobo even my grandma can do it my friend. Sometimes we sell refurbished to customer which even u out there never knew. We had successfully earn 80% margin which even sum times my cost us usd$5 for repairing. think-think

Can you help dianose what wrong with this Board base on your experience. Thank.

It boot and run fine with DVD Drive removed. With the DVD Drive connected to the Optical Drive bay, the leds and fan will flash, then power get cut off immediately. If I press the power swith to make a 2nd attemp to start it, the power will result in no respone at all. The DVD Drive had been tested good. If I start the laptop without the DVD drive. Then inserted the DVD drive into the Drive bay, the note book immediately cut off the power to the board, like short circuited.
I test this with the mother out side the case, same happen.
