UX380n power issue

Postby ruler » Fri Sep 13, 2013 08:16

Hello everyone, long time member and UX380n owner and recently my UX stopped powering on. Checked the AC adapter and it's working, the light on the AC adapter is on. So I took it apart today, inspected it and cleaned it up, everything looks fine no signs of damage or corroded resistors, etc, I also removed and cleaned the fan and heatsink, applied a fresh coat of arctic silver thermal compound, connected everything and attempted to power on but same issue.

So I plugged in the AC adapter directly in to the bottom AC adapter port on the UX (yellow connection) pressed in and held it in firmly while pressing the power button, luckily it fired up!! But as soon as I moved my hand and let go of the AC adapter (although still connected) it shuts off..

By now I figure i have pretty much isolated the issue to the internal connection on the UX (yellow connection) which is also the cable that is connected to the port where the dock/dongle/pci/wireless card is connected.

So I dock my UX and it powers on perfectly, and stays on!!!

My question is I guess I have a few options, either send in my UX to Sony for repairs which will cost $130 just to diagnose and depending on what they need to replace I will also have to pay for parts and service = potentially cost a few hundred dollars.

Find the replacement cable/ part where the AC adapter plugs in on the UX

Or my last and preffered option would be to just purchase a brand new exdented battery (VGP-BPL6) since it costs about the same as having Sony diagnose the issue (which I beleive I have already diagnosed as a bad conncetion/short) where the AC adapter connects.

So I just want some opinions or recommendations on what you guys think I should do?

And another factor To consider is my original factory battery has been dead since about the same year I got the UX which was around 2006, so replacing te battery with the extended baytery and just using the dock to charge it seems like the most economical and sensible thing to do.. What do you all think?

I wasn't able to order it, and can't seem to find another one. Would I be able to repair it ? or possibly find another one ?

Agree with your original conclusion - go get an extended battery (which could power the UX for up to 5 hours) and just charge it with the dock. Problem solved.

wow ruler, you reply to a thread you started 2 year ago. Either you do things really slowly, or you live in a different time alignment ;)

I have had that same issue you had a while back, and I found the only way was to either reseat the cables, to the part Anh mentioned. ie clean contacts with cleaning alcohol which is a temporary solution. The ideal solution is to order a new part. The official part number is


Maybe you could order the part from this website


Good luck

hope this helps
