Z50-70 pauses at boot time?

2014-11-27, 21:27 PM

After pressing the power button, the Lenovo white logo on black background appears and stays there for 137 seconds (2 minutes 17 seconds, always the same) no matter what, after which I get the boot loader and all works normally. It looks like it's waiting for some timeout.

This doesn't happen if I reboot: in this case it takes just a few seconds to get to the boot loader.

Any tips?

Thank you!

Please refer to this thread which discusses some steps that you can take to address your problem. You can also check the box with the label No GUI boot as shown in the picture.

I may have forgotten to say that I use Linux, not Windows 8.

But the pause happens way before anything like an operating system is loaded - even for accessing the bios (uefi) setup I have to wait the awful 137 seconds.

Here the results from some more experimentation.

The pause happens with a duration independent from the setting of the "Fast Boot" option in the bios setup.

It never happens when using restart instead of cold boot.

Sometimes (quite rarely, about 10% of times) it doesn't happen even with cold boot.

Most interesting thing, when it happens it always lasts a multiple of ~131.5 seconds: observed times so far are 132, 263 and 394 seconds, that is, 1, 2 and 3 times that duration, with the first case being way more frequent.

Any ideas are very appreciated.

In that case you should be posting in the linux forum section.

Hi,

as I have written the problem happens way before any operating system is started, and it was there (with the same features) also before I switched to linux, so I think this section may be more appropriate as it appears to be an os-independent problem
