HELP!

I think I’ve burned out the power unit in my laptop. I plugged my Sony TR2/AP3 into a car adaptor charger and heard a small popping noise and there was a burning smell coming from the power socket on the laptop.

After this occured the laptop battery lost charge as normal, but I am now unable to charge via the regular power supply. Can anyone tell me what part number I need to fix this problem??

Thanks in advance for your help!

I’m confused. The battery is dead and it wont charge, right? If you plug it in, does it work (but doesn’t charge)?

The charger and battery are fine, it’s the power unit inside the laptop that seems to have blown. I think due to an incorrect voltage from the car charger.

The problem is now I can’t charge the computer rendering it useless :(

Personally I suspect its a battery issue, since you are still able to run the notebook from the wall plug.  If you are sure its in the notebook, try using a continuity tester on the surface mounted components next to the power plug on the motherboard.  One of them will likely be a blown fuse.

Unless you’re experienced in repairing electronics, I think the best course of action is to find a reputable computer repair shop and have them do it for you.  Replacing small-surface mount components is something that takes a lot of experience to do correctly.  You could end up making things worse in attempting a repair.

This is not a battery issue! The battery and charger work fine. It’s the power supply inside the laptop that doesn’t work.

I used the wrong voltage and blew the power unit inside the laptop. I’m looking for the part number so I can replace it.

Please let me know if you know what this part number is or where I can get it.

Thanks!

Are you able to run your computer off the AC adapter?

Hi Rahul,

No, sadly not. It runs off a charged battery ok, but since the power connection is blown, it won’t charge using a power adapter or run off it. I took the laptop apart to see if I could identify the part, but there is no visable module. It looks like the power socket on the rear of the machine is connected directly to the motherboard :cry:

Sorry to hear that. It would be better if you contact Sony regarding this. Incase your warranty has run out you could atleast call them and explain them the situation and get an estimate of the costs involved.
