I have the T14s gen2 laptop, works fine as it should until last month they have a firmware update. I did the update accordingly and then the battery indicator failed always showing 0%, and the bio-system does not recognize that AC plug is plugged in, I could not set the computer to sleep. I called technical support, tech said the bio is corrupted I need to send the whole computer in for repair to reinstall the BIOS, and I will likely loose all my programs and data in the computer, so I did not do it hoping they will have a patch later on to fix this issue. I did all my windows power setting and sleep cycle numerous times to no avail. On 6-16 Lenovo has a bio firmware update, I was delighted and immediately downloaded it except it refuse to allow me to install because the bio don't recognize that my AC is plugged in and said there's not enough power to do the install. Today at 6-17-2023 I called the technical support for help, technician was rather impatient and told me it's a window 11 problem because "Microsoft did not set their updates to work with their firmware". We went around and around I was courteous just seeking help but and he hung up on me. Called the second time on the same day, another tech told me an entirely different reason and said my battery is bad. I said how can it go bad overnight after a firmware update? but if AC is plugged in then I should have enough power to do the install of the firmware update, the guy got impatient and hung up on me, again. Is this the culture within Lenovo? to hang up on customers when they could not solve the problem? last time I will buy a Lenovo computer, they suck!!!
