How we fix your Dell Inspiron 640m
We trace the fault on the board to the part that has failed, such as a power chip, capacitor or controller. Repairing that part is usually far cheaper than a new board.
Where a board can't be repaired economically, we source a replacement motherboard for your Dell Inspiron 640m and refit your drive, so you get your laptop back with your files and settings in place.
How long it takes
Board diagnosis usually takes one working day. We give you a price and a timescale before starting.
Good to know: Use your laptop on a hard, flat surface, not on a bed or sofa. Soft surfaces trap heat, and overheating is a common cause of board failure.
A 14.1-inch widescreen Core Duo laptop from 2006, the Inspiron 640m was also sold as the Inspiron E1405. More about the Dell Inspiron 640m
Common questions
Is it cheaper to repair or replace the motherboard?
Repairing is usually cheaper. We only suggest a replacement board when a repair wouldn't be reliable or economical.
Will my files survive a motherboard fault?
Usually, yes. Your files are on the storage drive, not on the board, and we check the drive separately.
