BIOS update M2WKT45A fixes tiny P340 disk performance

2021-04-09, 16:58 PM

I complained in the past days that the disk I/O in my brand new tiny P340 (WDC SN730) was significantly slower than on my tiny P330 (Samsung), about 1 day ago Lenovo released a BIOS update that fixed the disk I/O performance problems, now it is as good as the P330.

 

This is not a question to the forum, I share this information in case other members are experiencing the same disk performance problem with their tiny P340

 

The update was applied via Lenovo Vantage with no problems.

 

Regards,

Martin

I just applied this BIOS update but now when I power down using the Windows Power -> Shut Down, my P340 no longer powers off.

Any ideas of what the problem could be?

Fast boot is disabled in Windows.

Thanks

Do you have 1 or 2 NVMe installed?

There is a bug with 2 disks preventing proper shutdown.

I am having the exact same problem!

Any thoughts on this would be much appreciated.

Check the thread here

ThinkStation P340 Tiny BIOS M2WKT45A unable to enter Sleep or Shutdown with two M.2 SSD Installed-English Community (lenovo.com)

 

The only solution is to roll-back to previous BIOS and wait till Lenovo releases new version with bug corrected.

I have two but did not have this problem before this BIOS update.  Is there a quick workaround until the bug is fixed?
