Thanks harrisb!  Perhaps it will fix my 50 sec warm-boot delay...

Do you have the link for the 1.36 W520 BIOS?

http://support.lenovo.com/en_US/research/hints-or-tips/detail.page?&DocID=HT063273

is still at 1.35

Click on the link. It's really 1.36.

 

I've installed it and I still have the redock issue with no boot on first dock after running undocked and shutdown.

Re: BIOS 1.36 Posted

It is almost a year since the W520 was introduced and there is still the issue when system doesn't boot with USB 3.0 HDD connected. I just flashed this newest BIOS with great expectations that the problem was finally solved, but I'm pretty disappointed now. Here is the video of the problem (sorry for low resolution, it was uploaded directly from Windows Phone device): https://skydrive.live.com/redir.aspx?cid=56e4dfd93a183e61&resid=56E4DFD93A183E61!483&parid=56E4DFD93... This issue is there since the day I purchased this laptop and because the same setup worked fine on my old T61 I suppose it's only a BIOS problem. Please, Lenovo, fix this!
