Failed BIOS Update (Black Screen Yoga P40)

2016-07-02, 7:49 AM

Hi all,

 

I just updated the BIOS (Initiated from Win10), after restart nothing than a black screen and the keyboard lighting up for a second. (Thinkpad Yoga, P40) 

 

I tried to hard reset it (power button shutdown), again in combination with Shift-F8, drained the battery and tried again. But still dead as a dodo. Some ideas before I start the whole support procedure at Lenovo? 

 

Many thanks in advance!

You have to remove the CMOS battery, wait for 5 minutes and plug it back in.

I had to disconnect and reconnect both the cmos battery and laptop battery to resolve the issue.

Were you able to successfully upgrade the BIOS or did you decide to skip? I did not even attempt to install.

Hi everybody,

 

I just updated the BIOS, after restart nothing than a black screen and the keyboard lighting up for a second. (Thinkpad Yoga, P40) 

 

I tried to hard reset it (power button shutdown), again in combination with Shift-F8, drained the battery and tried again. But still dead. No responsible support at all? 

 

Many thanks in advance!
