Repair dead Laptop / notebook power supply?

post #1 of 5
Thread Starter 
Hello, all.

A friend has a dead laptop power supply (ac power adapter). It is for a Compaq V5000 laptop (very common power supply). I don't think it is as simple as a broken wire. The actual adapter (brick) has a power led on it, and the thing burned out or something. I didn't notice any burns or shorts in the cord. Also, no visible kink damage to the cord. Unfortunately, I don't have a multimeter to test for shorts, but I can get one. I have a 15w grounded soldering iron.

Has anyone here successfully repaired a DC adapter (the actual transformer block portion)? I know that replacement adapters cost about $50 to $80 on average, so I figure I might as well ask.

Thanks, all.

Wouldn't be worth it to repair it. They are usually a pain to take apart. I would just buy a cheap one on eBay for $10-$20, or use a decent universal for $25-$30.

Oh wow, I didn't know they were that cheap. Thanks. I figure the quality might not be good, tho.

BTW, the original one was plugged into a surge protector.

The cheaper "no name" ones are kinda cheap and light. However if you find a good seller on eBay, they generally give you a 1-2 year warranty on them. I've received a few bad ones or ones that went bad after a few months but that will happen with everything you buy. I've ordered a lot over the years for a previous employer and for my customers and would say 97% of the time you are good. Just be picky when you choose who to buy from and maybe even spend a few extra dollars on one from someone that has been there for a long time.
