Laptop doesn't turn on after turned off??

Jul 19, 2016 12:24AM PDT

I have a Lenovo Flex 2. Somehow when I turn off my laptop, it won't turn on back. I have to keep turning it on and off about every 10 minutes - 10 times before it would come on. It works perfectly fine if I just leave it on sleep.
I took it to two professionals and they couldn't fix the problem and neither did they understand why it was happening. What could be the reason? And how can I fix it?

P.S. I updated it from Windows 8 to Windows 10. I'm not sure if this would be a problem.

Let me share a story
Jul 19, 2016 7:45AM PDT

My son returned 2 laptops from his college days. It's something I ask all my family to do as I have run repair shops in the past and often can get an older unit back in shape then out to another student.

One in particular and it was not a Lenovo had a weird power up trouble. As I'm an old hand at this I had it on W7 and it was OK so I cloned the HDD to SSD as the laptop was getting too slow for today's crrowd (35 bucks for 120GB) and then took the deal on W10.

At that point pressing the power button didn't work all the time.

I hit the maker's web site to see about drivers and BIOS and sure enough one of the BIOS notes read about a power resume issue. Updating the BIOS was a little more work as the update app was only for XP to 7 so I slipped in the old HDD, updated the BIOS and then shutdown and slipped in the W10 SSD.

All fixed.

This does not mean this will fix your laptop. It's just something I ran into.

It turns on but doesn't show

Oh I think I forgot to mention. When I turn on the laptop the light comes on and the fan spins but it doesn't come up on the screen.

I will try updating my driver to see if that would work.

I shared the story but didn't detail all the effects. I felt the story would be enough.

It was not and NEVER has been a driver issue.

first thought - temperature

though you are running it till you turn it off, it could be running hot until it is cooled off. If you have a laptop cooling pad, try using it and see if it would keep the laptop cooler, cool enough to immediately turn on. If no cooling pad, try a fan and keep it blowing on the laptop as you use it and see if you have the same issues.
