How we fix it
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 Sony VAIO VGN-Z21ZN 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. Blocked vents make it overheat, which is a common cause of board failure.
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, which we check separately.
