Spectre 360 won’t turn on without charger

[Ahu98a]

My Spectre has been working fine until yesterday when it suddenly wouldn’t turn on without being plugged in to the power adapter. 

Tested the battery and it states it PASSED. Charge also won’t go above 94%. I have read others had the same issue down to the 94% charge display issue and wondering if it is in fact a mother board issue or if there was another way to resolve this. 

Thanks in advance

Thank you for posting on the HP Support Community.

• Did this happen after a recent window or software update?
• Did you try another charger?
• Does the notebook shut down immediately (right after you unplug the charger)?
• Do you get any error message on your notebook (Such as Plugged in, not charging, etc.)?

While you respond to that, let's try these steps: 

Hard Reset: Follow steps from the link: https://hp.care/2GnkMa8.

BIOS default: 

1. Turn off the computer and wait five seconds.
2. Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3. On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4. Press F10 to Save and Exit.
5. Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?

Hope this helps! Keep me posted for further assistance.
