Question:

I used a Friend's charger that output +30V & 333mA on my Toshiba laptop. its original charger outputs 19V & 2.37A.

The laptop died on the spot. The laptop does not charge anymore even with the original charger., no charging light, does not boot, nothing!

could this have completely killed it?

Am o problema cu un laptop sony vaio, din cate vad se pare are scurt pe ground, cand conectez incarcator acesta taie curentul, banuiesc sa se protejeze de scurt, dar cum as putea afla unde este scurtul fara o sursa care sa nu aiba protectie?

Just wanted to add something for a cheap substitute for freeze spray for everyone who doesn't want to spend the ridiculous amounts of money on a frequent use. It's called Poop Freeze for freezing dog poo and is from a cheap discount store for £1.99, 150ml. I know the £10 400ml works slightly better but I though it might help. That's not easy that was great, needed good eyes with the freeze, excellent bit of searching Sherlock. Show's the need of a decent bench power supply as part of your diagnostics tools with also experience. Nice one.
