Coins for Coins

Just replaced the BIOS battery in mother_bones' laptop. A CR2016 cell costs about 50p and we happened to have a spare one in the battery box; the laptop SKU replacement part is just one of those, with two electrodes attached to a small connector. It's shrink-wrapped so you can't easily replace the battery within. A replacement part costs about £8-20.

So I carefully disassembled the part, cutting open the shrink rap with a craft knife, removing the electrodes from the cell with a spudger, and removing the last of the shrink wrap. I replaced the cell, and reconstructed the part as best I could, sellotaping it back together.

It's a bodge, but it works - no more clock complaints on boot-up. Saved us a few quid, and I got it fixed tonight rather than having to wait for a part to arrive.
