Need to replace a CMOS battery inside my laptop. Turns out it's not as accessible as I thought. Don't really think I'm qualified or confident to dismantle the laptop myself - seems like it would literally require me taking about the whole thing. Anyone got a recommendation for a laptop/computer repair person in Central London? Quick google search seems to bring up a load of proper dodgy looking websites.

Or alternatively, suggestions to "MTFU and dismantle the damn thing yourself" will be welcomed.

Cheers
