Lenovo ThinkPad P52s: New internal battery not recognized

Wed, 10 Jun 2026 12:48:05 -0700

I just replaced the internal battery on my Lenovo P52s, but Windows 11 does not recognize the battery. I've done the following:

Removed battery devices and rebooted; they came back but battery not recognized.

Held down the reset button on the bottom of the laptop for 30 sec.

Removed external battery and power and held power button down for 30 sec to de-energize.

Any ideas?

Thanks,

Bob

The module says it's compatible with the computer but the flex cable is really long compared to the short p52s nfc cable. And the antenna says it works with the Module Thus working with the p52s. I'm. Just worried About the flex cable. Parts are From A thinkpad L480

Hi,

I think i've blown the fuse during the replacement of the LCD Screen.
Due to that the Backlight of the screen doesn't work any more.
Does anyone knows the specifications of the fuse I have to replace replace?

The Mainboard looks equal to the T580 smd fuse replacement video on youtube, that I found.
