Spectre x360 13-ap not charging anymore after upgarde to BIOS F22

Spectre x360 13-ap
Microsoft Windows 10 (64-bit)

After the latest BIOS upgrade to F22 the notebook is not charging anymore. AC adapter works, as verified on another unit, however the Spectre won't charge anymore, charging LED stays off. Nothing else has been changed on the sw load. Any hints anybody or able to repro yourself? Can't recommend to upgrade to F22!

Have you run a diagnostic on the battery? How old is it? Although it would be a huge coincidence its possible the battery was on its last legs anyway when you did the BIOS upgrade. But the battery test will tell us the condition of the battery and if it looks good as far as cycles and remaining cell power then I will agree the BIOS flash killed the charging of the battery.

The battery test shows the battery as ok and with 97% battery capacity left.

There is more to it than that - # of  cycles and the charge capacity of each cell but frankly unlikely to be any issues if it tests at 97% original capacity...so the BIOS may have done it. Are you under warranty? You could try disconnecting the battery briefly and plugging it back in but I hate to have you do that if there is warranty left.
