G780 hangs at power up with drive light solid on

My G780 has recently developed the problem that it won't start up, properly.

It has a Crucial SSD Crucial_CT250MX2 running Ubuntu Mate 16.04

I press the power button, the lights come on and all stay on when it has this problem.

If I disconnect power and R&R the battery then the next few times it behaves normally, the lights come on, the drive light shuts off and boots with random flicker on the drive light.

 

Thanks, Fred

Re: G780 hangs at power up with drive light solid on

Hello FredY42

Thanks for using the Lenovo forums.


Try a static discharge for this, it may help to resolve the issue or at least get rid of any built up static on the motherboard.

(If the battery is internal, please just skip the remove/replace battery steps.)
1. Turn the unit off
2. Remove the battery and the Mains adapter
3. Press and hold the front power button for 30 seconds
4. Replace the battery and the Mains adapter
5. Turn the unit on as normal

Hope this helps, let us know how you get on.

Re: G780 hangs at power up with drive light solid on

None of those helped. So I concluded it was probably the Crucial SSD. Replaced it with a Samsung 850EVO.

Worked fine for about 8 weeks and now it is back to the problem again.

 

Is this possibly a BIOS problem?

Any other thoughts?

 

Thanks, Fred

Another thought on the problem:

 

I almost always wait for an orderly shut down. I start the process though software and wait for the power light to extinguish before I close the lid.

 

But every so often when theshutdown process starts taking too long I get impatient and close the lid. I had the power switch and lid close set to poweroff.


Since I have already started an orderly shut down sequence through software, is it possible that the lid action interrupts that sequence and simply cuts power causing an disorderly sequence and maybe causing my intermittent dead at POST problem?

Yes, I am reaching for an explanation. But I would love to solve this problem.

Thanks, Fred
