No power: motherboard repair
If the Vaio VGN-CS31ST/R shows no lights at all, the fault is often a failed component on the motherboard rather than the whole board. We trace power faults at component level, which can save a laptop that would otherwise be scrapped.
Battery and power
Original Sony batteries for the Vaio VGN-CS31ST/R are no longer made, so we fit good-quality compatible batteries where you want the laptop to run unplugged. If it won't charge at all, the DC jack or the charging circuit on the motherboard is often the cause, and both can be repaired.
Virus and slow-running problems
Pop-ups, slow start-up and strange behaviour on a Vaio VGN-CS31ST/R are often caused by years of accumulated software and malware. We remove it, clean up start-up programs and, if needed, reinstall Windows with your files backed up first.
Is it worth repairing?
Sony sold its PC business in 2014, so new original parts for the Vaio VGN-CS31ST/R are no longer made. We use quality compatible or reclaimed parts, and we'll tell you honestly whether a repair is worth it before you spend anything.
