Sort of: internet access no longer a problem, even though the chap at the little shop to which I took the laptop had to wipe it to fix the problem of my being locked out. I'd had Windows 11 for a couple of years, but when I collected the device & got it back home, it had reverted to Windows 10. I finished downloading Windows 11 again earlier & so so far, so good. However, I've yet to discover whether it will resolve the issue with my e-mail which I encountered yesterday evening, viz. that I was unable to open Windows Mail properly, no matter what I tried (hardly surprising, given that I'm functionally illiterate in all matters IT, so I probably did something wrong when I first attempted to open it. I can't even remember where I found the option to move the Windows 11 icons in the system tray from the centre to the bottom left of the screen the first time!). Microsoft had moved me over to Outlook a month or so before the trouble blew up & I was getting used to using it, hence my hope that the switchover will have the desired effect. Luckily, I can still get at my web mail.
There's still a more serious problem, however. While he was working on the laptop's innards & after he had replaced the battery, my little man discovered that it wasn't taking/holding its charge. Further investigation revealed that that was because of some broken component in the motherboard which could be fixed only if the motherboard were replaced - at a cost of £400, which I rejected out of hand! Not only that, but he had found that the section of the connecting cable between the laptop & the adapter (the one I bought direct from Dell about 18 months ago!) was broken at the point where it went into the adapter (the bit that's covered by some kind of plastic sleeve). I can live with the need to keep it plugged in to the mains for the time being, especially as the man gave me a £25 adapter without charging me for it, but I'm going to have to bite the bullet sooner or later & invest in a new machine, so I'll have to do a bit of research for a suitable 17" replacement.

You should not be paying £400 for a motherboard, unless it is integrated with memory and a graphics card.
I buy them for a living and you can get a decent motherboard for $120 if you know where to buy from.
