Hello,   I am having the same issue with my 5540. I have run the diagnostic and the bios is updated. I thought it might be the power supply, but that has been changed as well. Everything is OEM. Not sure what do do next? Any advice would be great!

PS, 'Dell Command Update' and 'Windows Update' shows that my system is up-to-date.

Thanks

Hi there,

Do you know of a solution for this? I've been having the same identical problem for some time now. 

BIOS check and SupportAssist diagnostics on my OEM battery gives  'excellent health'/'pass'.

Thanks

First point:  How old is the battery?  Is it original to the system?

Second:  open a command prompt with administrator privilege and type

powercfg /batteryreport

What are the numbers for the design and current capacity of the battery?

That does not answer the relevant questions:

How old is the battery?  This system dates from 2016, so if the battery is original, it's six years old and likely in need of replacement (and yes, battery health can be reported "excellent" even with some tired cells aboard that result in a voltage drop that cuts power).

Second, run the powercfg /batteryreport command, which will tell you what the current charge state of the battery is.  If it shows a number that's below 60% of its design capacity, the battery needs to be replaced.

Once you check the battery status, post back and someone can assist you further.  If the battery shows that it is OK with the battery report and it's newer than the system, that suggests the problem is with the system board, not the battery.

Hi ejn63,

Thanks for the quick response. It is indeed a replacement battery - a genuine Dell battery installed around 1.5 years ago. I've run the powercfg /batteryreport command, and the results are as follows:

Information about each currently installed battery
BATTERY 1

2022-07-21 00:18:58 Report generated AC 100 % 57,692 mWh

That would absolve the battery - leaving the solution:  replace the system board.

Hi Guys,

Just to let you know. I solved my issue!!

Problem was caused by a faulty connection between the battery cable and motherboard connector. 

Solution was to give both a precautionary clean with a electrical contact cleaner and then tape down the cable to the connector using circuit board tape.

So it seems that the cable was 1) not making complete contact on all the pins, and/or 2) the connection was not solid/stable and  could wiggle loose slightly.

Happy Days:)

The charging circuit on the motherboard is probably bad.  That allows the battery to accept and provide current. When I worked in a previous job years ago supporting hundreds of laptops, we had a few of these. If I'm right, I suspect that as you wait for your battery to self-discharge over time, you'll find that it battery won't charge anymore either.
