Go here: http://h10032.www1.hp.com/ctg/Manual/c05... Look on the top of page 15 - it tells you the kind of solid state drive you can use in your computer. Check the two PCIe NVMe drives. I’m pretty sure that this is what you want. But when I looked up the part number (L01520-001) on one of them, I couldn’t find the part. Looking up parts on the HP website is hopeless. If you can find one of the two drives that are listed there, you will be able to see if it is the type of drive you are looking for.
Did you know that you can buy this exact same printer at Walmart.com for $49.99 refurbished? https://www.walmart.com/ip/HP-Officejet-4630-e-All-in-One-Printer-Certified-Refurbished/945174726 It might be worth looking at that rather than at trying to change the glass.
Your printer may think it is out of ink. Try the following: https://itstillworks.com/reset-brother-ink-cartridges-4740636.html Also, do a cleaning cycle or two, both black and color. Do a deep cleaning if the regular cleaning doesn’t work.
The ignition switch may not be very expensive. There are probably two parts to the ignition switch - the part that you put the key in, and the electronic part behind the key switch. The electronic part is the part you may need to replace. I bought this part once at Auto Zone for around $15. Replacing the electronic part of the ignition switch fixed an electrical problem my car had. I would start with that part. If your starter tests good, then the problem isn’t with your starter, it is with the part in the car that tells the starter to run. It occurs to me that you might be able to run a mechanic’s switch to your starter, then turn your key on and push the button on the mechanic’s switch when you want to start your car. (That’s also known as “hotwiring” your car.)
You might try wrapping some tape around the plug in order to make it thicker. If it is thicker, it may stay in the socket better than it is now doing, and if it therefore stays in the socket, it may be able to charge.
How far along does it get in the boot process? What shows on the screen during the boot process? What is the last thing to show on the screen? What do you mean when you say “boot manager”? What is showing on the screen when you are at that point?
