Windows 10: Laptop restarting instead of shutting down when clicking shut down button

Hey Microsoft Community, I'm experiencing a frustrating issue with my laptop. When I click the Shut down button, it restarts instead of shutting down. To turn it off, I've been pressing the power button for a few seconds. Please help me resolve this issue.

Laptop Refuses to Shut Off


Hi, Phil. I'm doing what I've always done: slide the cursor to the lower left screen and click on Shut Down. But instead of shutting down the laptop responds as if I hit Restart.
Just tried your suggestion and hit shift but it made no difference. Laptop rebooted.

 

Laptop Shuts Down instead of Restarting when clicking on Restart

Laptop will Shut Down normally when Shut Down and power on normally. If I choose Restart instead, it just Shuts Down and never Restarts. When attempting to power on after the failed restart, the keyboard lights up for about 10 seconds, black screen, no fan noise, and then it shuts off. The only solution I've found to work consistently is to open up the back, unplug the battery from the motherboard, and plug it right back in. Powers on normally every time after doing this. If, however, my laptop is plugged into my external monitor, and I choose Restart, everything works normally, and it will power on automatically like it should. I've tested this numerous times with the laptop by itself and connected to my monitor, both on just battery power and on just AC power, and it's the same findings. Never had this problem before until I recently had to change out my keyboard and DC power jack. I upgraded to the latest version of Windows, and tried some old Macrium backups to test if it was a software issue, and this problem occurs on all versions. I'm assuming this is a hardware issue of some sort - my guess is battery but its charging normally, still 80% health, an in excellent condition according to Dell Power Manager. I have tried uninstalling Battery drivers and reinstalling them and holding the power button down with no battery and just the AC Adapter plugged in for 30 seconds. I will attempt to order a new battery and battery cable that connects to the motherboard to test, but if anyone is familiar with this issue please let me know. Windows 10 1709 (16299.1127)

 

Random shut down and restart??

Computer: Intel (R) Pentium (R) Dual cpu
E220@2.406hz
2.42 GHZ, 2.00 GB of RAM
Windows xp

Ever since I replaced the fan (with heat sink) the computer has randomly shut down and then restarted, at first during streaming, and now, will shut down and restart anytime. I tried to replace the graphics card to no avail. *Confused *Mad

One suggestion was to replace the RAM.

Any suggestions on how to repair my computer?
