[Bug 1303131] Re: [Lenovo b575e] Display remains blank after resuming from suspend


Jure Repinc, could you please contact Lenovo to confirm this result?

I've never seen this phenomenon across hundreds of BIOS updates for
Lenovo devices (both linux and Windows), so it's a little strange to say
the least to see the version number and date go backwards on a "newer"
BIOS update.
