Hi Joe I have a unit now with the MBX 49 board that is totally dead does not charge battery or work from a known charged battery.
The small fuse at the rear F2801 is OK, 19V on input to Q2803 nothing out from one that I worked on earlier I noted that this should have
19 on the output. This is a fet and is not being swithed on as the gate is also at 19V not pulled low as for P channel fet.

What model PC did this come out of?
Gsxr Nutter,
I?ve worked on a few Viao?s in the past and haven?t run into a motherboard fuse nor have I seen any references elsewhere. That doesn?t mean there isn?t one, just means I can?t find any reference to one.
Can you actually see a fuse on your board or are you having problems powering up your laptop? If it?s the latter laptop power issues are more typically related to the AC adaptor, the power socket/plug. Let us know..
