Ebay Gives Incompetent Buyer Full Refund Including Postage

[norm2500]

I sold a working bare motherboard to a buyer with only one previous Ebay purchase at the time. About a week after delivery he said it wasn't booting and claimed a full Ebay refund of  purchase price and postage.

The buyer returned the motherboard, and on inspection I found the "CMOS Clear" jumper had been moved from its normal Pins 1-2 position, where it was when I posted it, to Pins 2-3, which all manuals say will damage the motherboard if booting is attempted while in this position.

I showed my partner, photoed the  changed jumper and some bent IDE pins, put  the jumper back in its normal position, and retested the motherboard. It wouldn't boot. 

Then I emailed Ebay pointing out the changes and damage and included photos.

Today Ebay have told me they are ordering a full refund to the buyer (including the postage I've already spent to send the motherboard to the buyer) and PayPal will enforce this with a charge on my account.

What can I do?

That battery needs power doesn't it, as in, could it be flat? For the board to boot and for the real time clock. I have had boards that didn't work with a flat battery. If left in the reset BIOS state (the part of it that's suppposed to be cleared) it could have completely discharged. Maybe leaving it like that could kill the chip also.
