Is it just that the battery never gets charged, or does the laptop indicate a problem with the charging?
Physically, the Battery-status lights glows white, which means that the laptop is charging. In the BIOS, the battery status page indicates that the laptop is charging, but the percentage charge never increases (it said 7% last time I looked). In the OS, the battery status icon indicates that the laptop is *not* charging, the percentage charge is 7% and the laptop will shut down in 1 minute.
Is this socket for the connector with the nine coloured wires? Perhaps the charging circuit only supplies measurable power when a protocol is followed across those wires; something the battery can do.
Yes it is, and you may be right, but I have no data on this.
Is there a service manual which gives more precise directions for this kind of diagnostics?
There's a service manual, but it doesn't give anything useful in this instance. I searched for the circuit diagram, but the only sites with any information appear to require login to retrieve the info.Other laptop info that I've seen (eg on YouTube) appear to show that the two pins that correspond to this should have voltage on them. It has occurred to me that I could use my bench PSU to charge the battery directly (eg out of the box), but I don't want to do that without more info.
Does it look like your original battery?
I think so. I replaced the original with a compatible item from Duracell, when Dell let me down in May.The spec matches.
Whilst working through this latest problem, continue to use the laptop plugged into the mains so any other issues also come to light.
I can't do that (see above)
