Toshiba Laptop Repair in London

[Tom Hukins]

Hi, Mongers.

A friend has a year old Toshiba laptop with a broken DC input jack.
Toshiba have decided this consists of reasonable wear and tear and so
want to charge £80 just to look at it.  They refuse to estimate or
guess how much a repair might cost.

So, how should I go about getting this laptop fixed?  Do you know of
anywhere in or around London (the nearer Sutton the better) that would
do a good job?
