Dell laptop, occasional boot problem – Hardware, Bios or OS problem?

Quick update on this, it doesn’t appear to be a battery problem. I’ve recently noticed a light tap on bottom and it will boot normally on next attempt. Some kind of bad connection I assume, but not sure where to look since it always hangs before Dell logo screen appears with drive indicator on solid. Something in transition between hardware checks and what ever occurs after that before Dell logo page.

I had issues with my Dell laptop last year due to a loose GPU cable connection with the screen caused by a partially broken hinge which allowed the cable to flex. Might be worth checking but I had to disassemble the laptop to fix it.

Just to update this thread, I’ve not found anything wrong with hardware or connections which I added to things done in list of post 1.

I feel safe to say it has to be something with Windows 10 and this slightly older laptop (system 1) because I have absolutely no problem with my newer PC (system 2). Along with fact that every time there is a win 10 update, the problems seem to change and vary. The boot problem has mostly cured itself and now laptop has moved on to random freezes that sometimes recovers after several minutes or other times requires a hard power down to reboot. Also the sideways happy face blue screen saying system has encounter a problem, data being collected and will restart computer. Which sometimes it does reboot, other times it just shuts down or says it will but doesn’t just simply turns off the display.

Wish I could mark this thread as solved, but it isn’t and suspect never will be with this slightly older laptop on Win 10.
