Just finished fixing The Boy's laptop, wot had died from a poorly fan. Scored a replacement off Ebay for a few quid and using the excellent Lenovo hardware guides removed this, undid that, dropped the other and put the new fan in. Note, not a complete cooling module, just the fan, so some amateur metal working was required. Even put new heat sink paste on.
Tools used: Tiddly cross head screwdriver, slightly larger cross head screwdriver, small pliers, Mora Clipper knife. No swearing, one glass of red wine.
Only two bits left over, both of which The Boy had removed earlier.
I call that a result.
