Lenovo Legion Y720 Battery/Charger issue

2020-09-14, 13:09 PM

I have a Lenovo legion y720, which is acting up.

When power adapter is connected along with the battery, i cannot turn on the pc, i mean, it powers up, but the screen will not turn on at any point, nor with external monitor.

i can boot with either connected alone no problem, but if i connect either afterwards, the pc just freezes.

Both a new battery and charger has been bought, issue persists.

i can see a bios update available, but cannot install due to both battery and ac adapter needed to be present.

 

tl:dr laptop work with only either battery or power adater connected, not both.

I got help from Lenovo Support in regards to update the BIOS which solved the charging/Battery Issue, but unfortunately that created a new and even worse problem.

 

The FAN's does not spin up at any point, not in uefi/bios nor when the pc is booted into windows.

 

 i installed Speedfan to see if a fan was detected, but it couldn't find any.

 

anyone got a tip or a way to roll back BIOS to the previous one, it won't allow it normally, as the one installed is newer.
