Sorry for the delay responding. Info comes from http://tech.groups.yahoo.com/group/Laptop_Repair/message/646 Joe K Sony Vaio 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.

Look on eBay and Amazon. You should be able to find one at those sites for a reasonable price.
