Update on HP laptop and the daughter's one too!

I forgot to update on the laptop which I mentioned a few weeks ago. As I said at the time, we suspected the problem with slow running (and maybe even failure to charge the battery) was down to a broken up power socket on the laptop motherboard. Well, a spare was found on an old motherboard and eventually (we needed a more powerful soldering iron!) swapped with the broken one. A slight snag happened when the cable for the touchpad and buttons was damaged during reassembly, but that was bodged fixed with some soldering too!

The repair worked!  The laptop now runs really fast and - as an added bonus - the battery charges and is actually rather good, holding a charge in general use for 3+ hours!

Daughter's Lenovo laptop is still working perfectly since I removed the dead battery. She has to use it plugged into the mains of course, but that is a mild inconvenience compared to buying a new machine!
It also earned me kudos with her!
