Thinkpad E480 freezes when entering sleep

2018-08-18, 7:35 AM

Hello,

 

I have an intermittent issue with my Thinkpad E480 when it enters sleep/hibernate. The screen turns off, but the white light on the power button stays on, and the red light on the outside of the case stays solid. The laptop is unresponsive; I have to hold down the power button for 5 seconds to reboot it.

 

This doesn't happen every time, maybe around 50% of the time after either timeout or when I close the lid. It can happen on battery or AC, regardless of what programs I am running- sometimes even when the laptop has just booted and sitting on the login screen.

 

I am on Windows 10 Home, latest version of BIOS (1.18). I've tried:

  • Enabling/disabling hybrid sleep mode
  • Enabling/disabling wake timers
  • Enabling/disabling 'Turn off hard disk affter x minutes'
  • Using either sleep or hibernate

 

I've searched a fair bit and haven't found anything that can help. Does anyone have any ideas? Thanks in advance!

TP

This happens to my E480 as well. Already tried to load bios defaults. That didn't help either.

I fixed this today on my E480.

I downloaded these 3 drivers from the support website and installed them. (Lenovo Vantage said I was all up-to-date)

Lenovo Power Management Driver, ThinkPad Monitor INF file, and Intel Chipset Device Software.

The filenames were: r0pch04w, n2hku54w_x64 and r0pmi07w.

And obviously rebooted afterwards.

Hope it helps someone.

Thanks for this. I tried installing all the latest updates; the best configuration I have is to put everything on Hibernate in Power Settings (as opposed to Sleep) and it seems to work. Hibernate seems a bit slower to resume but still faster than hard rebooting my laptop every time I leave it unattended.

 

The only scenario where it is consistently broken is when I leave it sitting on the Windows login screen, it goes to the black screen and then hangs, requiring a hard reboot. Fairly minor but still disappointing to buy a laptop with these issues from day one and still have no fix.
