Sony Xperia XZ Premium review: Hands-on with the new 4K HDR phone with Motion Eye camera and Snapdr5…
This is a bit of a long shot, but I'm faced with SWMBO's laptop with the common problem of the dc jack playing fast and loose. Unfortunately, I can't find online any help with the disassembly procedure for the Z91. A few other models, and a 'User/Hardware' manual, but they're no help here.
Someone may be able to link me to a source, or, failing that, would there be a 'generic' procedure for the order in which it would be sensible to remove items from any similar laptop ? For example - battery, then hdd, optical drive, wireless cards, ...etc. Regards all, John
Hi onthelimit1, and thanks for posting.
That was the nearest that I too found, and I'll be using the list they give as a guide if nothing else turns up.
I have found comments that Asus are very reticent with there help, so I expect the worst !
Problem solved !
Being a tad nervous of destroying the laptop, I had a dry run, taking off the obvious units from underneath. First the battery, then the hdd, then wireless card and memory, then the optical drive, and finally the cover over the pcu and heat sink. I then could see the pins of the jack poking through the motherboard, though somewhat hidden by the heat sink. It was obvious that the solder round the pins was cracked, and wiggling the plug in the socket, I could see the slight movement that was producing the problem.
Removing the heat sink was straight forward, 4 screws, and it just needed a slight twist as it was slid out, to clear the plastic base, and I had clear access to the pins. My 30 watt soldering iron did the trick, and we're back in business.
So faced with another one, I'd just remove the battery, then the pcu cover and heat sink, and go for it - 7 screws in total. As it happened, the jack I bought off ebay had the pins in the wrong position compared with the original, so it was just as well I didn't need to replace it !
It's very clear that the continual load put on the jack, pushing the plug in, or having the power lead dragged sideways, will be too much load for the solder tabs to cope with, without some positive restraint. A crazy bit of design by the makers, but then what's new ?
Good for you, I always think things are worth a try and very satisfying if one is successful.
