Start by removing all plug in items from the MB, except the CPU. If you get POST beeps indicating something is missing, add that part back in and try again. Proceed till you find something that stops the post. If it doesn't run form the get go, then you have an issue with the MB or CPU.

I have upgraded 2 laptops that are ancient by today's standards. 1st, use Macrium Reflect Free to create an image of your current system. That way it is an easy restore if the upgrade doesn't work. 2nd, Make a separate backup of your files 3rd, download a W11 ISO image. 4rd, download RUFUS. 5th, Get a USB stick = I use a 16GB one. 8GB MIGHT work. 6th, follow RUFUS directions to create a bootable USB stick with the bypass fix 7th, set the computer to boot from the stick and proceed to do a clean install. You will delete the system partitions and recreate on new partition out of the unallocated space. If you have a D: partition, DO NOT DELETE IT. Just make sure the C: partition is large enough. Mine is about 100GB, but it depends on you. 8th, test the operation. If all is well, proceed. 9th, reinstall your programs 10th, Reinstall your files. FYI, I prefer to create another partition on my drive (D:) and place all my files on it. It requires changing the location of the user folder, but it is easy. If you do...

Who had access to your phone lately? Sounds like someone is playing games with you. get after them.

My first guess would be the battery. The extra SIM causes more current drain, so it doesn't even have enough power to start. BUT, it could be something else.

It is shutting down because the power circuit is detecting a serious high power drain. Something on the MB is likely shorted. On my Dell, it was a bad CPU.

Battery swelling is a bad battery - replace it NOW. Do not charge it again. Run any charge down and leave it that way.

Now I googled and got this. 4 Blinks: May indicate a horizontal or vertical deflection issue, or a problem with the T-Con board you should learn how to do that.

your key broke. COME ON. WE AREN'T MAGICIANS OR CLAIRVOYANT. I can't walk, Can you tell me why???????????????????

Check the door seal carefully. You may have to pull it off to verify the door will fully close. My sister's GE had that problem. I couldn't tell just looking at the seals when closed. After pulling the seal off, it was obvious the door was hitting something. The bottom drawer in the freezer was holding the door open ever so slightly. I pulled the plastic off the front of the drawer and everything was fine.
