Do you get a power light when you plug in or try to boot?

Re: Thinkpad P70 doesn't boot

It sounds like you have found the "bug" that has frustrated many over in this post:

https://forums.lenovo.com/t5/ThinkPad-P-and-W-Series-Mobile/Thinkpad-p70-does-not-turn-on/td-p/33315...

 

The last few pages are the most useful, but in summary:

-Unplug power and remove battery

-Remove the keyboard to get to the CMOS battery, which you need to remove.  Make sure that all power is drained from the computer by attempting to turn it on with everyting disconnected.  Then short out the CMOS battery terminal.  -Repeat the process, then reinstall the CMOS battery, put it back together and you should get it to boot back up.  You will need to reset the date/time, etc. in the BIOS after this.

-Disable Windows 10 Fast Startup (this was the culpret for me)

-Update BIOS etc. to latest as per the thread above.

 

I lived through this for a week before I found this solution, so I feel your pain and wanted to get you the information quick on how to get back up and running.  Hopefully this works for you!

Re: Thinkpad P70 doesn't boot

That's awesome!  So great to hear Smiley Happy  My heart sank when mine did this and I am glad that I can help you not be stuck like this for over a week not knowing what the issue is.  I think this is more of a Windows issue than a Lenovo/Firmware issue.  It just sucks because it does rub people the wrong way about the product, which I don't think is really at fault in this case.

 

Glad I could help!!

Re: Thinkpad P70 doesn't boot

I replied to your earlier post on the other thread but it should be a yellow item under the keyboard but also under the RAM shield.
I own a Y510p SLI (retired), Yoga 2 Pro, X220T, P50 4K (sold), X1C5
