Re: T540p BIOS upgrade to 2.21 -> boot problems

Due to customer reports of unexpected problems booting up after upgrading T540p laptops to BIOS v2.21, the BIOS has been removed. The current BIOS available is v2.19.

 

A new BIOS that resolves this issue is scheduled to be released in early February.

 

When it is released, the update utility will be posted here: http://support.lenovo.com/us/en/products/Laptops-and-netbooks/ThinkPad-T-Series-laptops/ThinkPad-T54...

 

Thank you,

Hi,

 

I have the same problem. Since version 2.22 up to 10 attempts needed to boot. What is this for a Bios-Quality?
