Motherboard repair on the HP ProBook 6400

The HP ProBook 6400 has either integrated graphics or a separate graphics chip, depending on the configuration. Common board faults on laptops of this type are failed power controllers, shorted capacitors and damaged charging circuits, which we repair at component level.

What we do

We measure the board's power circuits to find exactly where the fault is, then replace the failed parts under a microscope using hot-air and BGA rework stations.

If a board is too badly damaged to repair economically, we tell you before doing any work and quote for a replacement board instead.

How long it takes. Many board faults are fixed the same day. If a part has to be ordered, we tell you how long when we quote.

Warranty

This HP ProBook 6400 repair is covered by our 90-day warranty on parts and labour.
