HP EliteBook, PN D4D58UC#ABA new battery -- all reports say battery charged to 12% but not detected

[Mudhen10]

Laptop sat for several years, old battery very dead. Changed to WIN10 and put in new battery which started charging and charged overnight - next morning computer showed battery at 12%.

Ran WIN10 battery check, ran DOS powercfg/batteryreport test, ran HP Support Assistant Battery Check and all give same result which is:  battery at 12% AND NO battery detected.  Laptop does run without the AC power adapter connected but goes direct into power saver mode and tells me to hurry up and connect to AC.  Before I take this to MicroCenter Support, I thought I would see if someone would have any idea of what is wrong.

If the full HP battery check showed 12% I am not clear how it is not detecting a battery at all. Can we see the full advanced output of the HP Battery check either from HP Support Assistant or UEFI (tap esc as you power up then F2 for diagnostics). Only 2 different options: 1. Your new battery is defective; or, 2. sitting for so long the motherboard charging circuit is bad. I would physically check the place where the battery plugs into the motherboard to be sure there is no damage or debris.

Huffer, I am also not clear how the battery is not detected but that shows a % charge.  I dont know how to post documents to this exchange so am doing screen shots of the HP Support Assistant Dashboard and Battery Check as well as a screen shot in 3 parts of the html document resulting from the DOS Battery Report (powercfg/batteryreport).  Hope this helps.  I dont know what the UEFI tests will show since I only see Memory Test (which PASSED), Hard Drive Check and Language, I have not yet run the latter two tests.  Your two options make absolute good sense.  I just want to do all I can do here at home before taking it to an approved service center.  Thanks for you help.

Huffer, by the way, I just did a F1 System Information check and it gives me the serial number of the battery that the system cannot detect -- confusing.

Yeah this is odd to say the least. You do not have the full UEFI installed. There is a stripped down UEFI in the BIOS chip but if you want all the diagnostics the full suite of UEFI apps has to be insalled and its a download from your driver page for your model

Huffer, thanks.  I followed the link, downloaded and installed the sp file and ran the System Tests.  The Battery Test Failed. Gave me a 24 alphanumeric code that I will provide to MicroCenter Tech.  Battery will now not recharge from the current 6% to the 12% or the 20% that it got to on the first night of charging after purchase.  Thanks for your help.  Oh, HP Tech Support will not talk with me due to the computer being so old and out of warranty - they told me to go to an approved service agent.

The alphanumeric Code has no state secrets it just means bad battery. Most of the characters just identify your model and the date of the test for warranty purposes. The battery just needs replaced I would wager. A small but fairly constant percentage of new batteries are bad from the factory.

Huffer, just wanted to provide an update to your assistance.  I exchanged the new battery or another new battery, installed and let it charge overnight -  BAM!  Fully, 100% charged.  Was a bad new battery like you suggested.  Thanks again.

Not my first rodeo, but thanks for letting us know you got it resolved!
