Thanks one and all.
Porker, done that as i've been inside to change the hinges recently and all is ok.
Scaredy, that been done as well.
Adidat, yep its antique, but until you come down and part with some more of you lovely £ notes it
wont be happening, oh wait you've had all my best gear !!!!
Now is definitely the time to double-check you have backed-up everything on it that you don't want to lose.
Having done that, I think I would want to rebuild it, software- and operating-system-wise. But when you say it is getting hot when it is supposed to be suspended, that means something isn't as it should be and a process or subsystem is continuing to work when it probably shouldn't. It is old enough to have a power-hungry version of Bluetooth. That might well be causing issues. I would try disabling that temporarily, and see if the symptoms go away. You obviously are comfortable going inside these things, and thus know the layout: from feeling the outside of the case can you tell what is getting hot - power supply area, CPU, or something else?
TBH though, it also depends on how you are using it. There are a few oddities about Apple WiFi behaviour. Both my daughters, and my son and daughter-in-law have iOs phones, and one daughter has a recent (solid state) MacBook. There are also two iPads. Together they are easily capable of crashing my WiFi access point, to the extent that I now reboot the AP first thing in the morning (when they're all here together), as it will have probably crashed overnight, and that's quicker (on the way to the bathroom) than walking upstairs again after finding my tablet has no connectivity at breakfast!
The issue seems to be to do with video streaming (Netflix), and it is probably my AP's firmware (TP Link), but the fact remains that it doesn't happen with the many Linux boxes in the house, nor with the iPad, nor with Android devices - only when there are lots of Apple devices at one time.
Daughter #2's Macbook used to do this on its own, but ditching Virgin's "super" hub in favour of a Ubiquiti Edge firewall/router solved that one (Virgin's kit no longer does any routing nor WiFi).
That saga, combined with the current "too many apples" issue, is why I suspect Apple's WiFi implementation rather than merely my own WiFi kit. Clearly the TP Link unit doesn't fail gracefully, but that isn't the whole story, or so it seems.
On the face of it, it seems you have a hardware/firmware/software issue on the Macbook, but if there is loss of connectivity, that might not be the whole story.
Just sayin'.
E.
PS: if it is old enough to have a network connector (RJ45), or you have a Thundebolt network adaptor, try a cable instead of WiFi (and disable wifi too). That may help you narrow the problem down. You might conceivably have two distinct problems happening at once - wifi and some age-related hardware failure, causing it to not sleep/charge properly (might explain the heat). But without more detail, this is educated guessing!
