I took my laptop into repair place - he looked it over and came back to me at end of day with a repair price - it needed a new battery and keyboard and system reinstalling, and I accepted quote.
He's come back to me a couple of days later saying it's not worth repairing because there is a short circuit in the motherboard, and that this has fried the new battery. He is asking me to pay £40 towards the cost of the battery he ordered that is now useless.
I have looked online, and it appears there are ways to tell if motherboard has a short circuit before ruining a new battery.
AIBU to think that a repair shop should have checked this first, and I shouldn't be asked to pay for this, since I now have to buy a whole new laptop and this one has not been repaired and is useless to me.
Or is it totally reasonable for me to be asked to pay towards his losses on trying to fix it?
