This may help you. Recently I upgraded an old DELL Inspiron 6000 to an SSD mSATA drive (Kingston 120G SSDNOW UV500) and it worked amazingly, for its age, with Windows 10. Of course I had to use an mSATA to IDE adapter but you might use an mSATA to 2.5” SATA adapter which are quite cheap and easily found. Just an idea. Let us know how it goes?

Have you looked over the IFIXIT guides for this model? Acer Nitro 5 AN515-53-55G9 The battery replacement guide shows the parts best. This may also help to show you how to remove the drive properly: https://us.answers.acer.com/app/answers/...-drive-installation-instructions-for-acer-aspire-nitro-5 Your hard drive looks like it is sitting on the cover so I’m guessing you did not take off the hard drive cover off, gently removed the hard drive and disconnected its cable, before removing the main cover? Maybe not? I see the hard drive connector, in your not very clear photo, connected to the drive sitting on the main cover so it looks like you inadvertantly yanked the other end of the drive cable away from the connector ON the motherboard. The ribbon cable connects near the cooling fans. If the fan is covering it So flip the cover over and correctly remove the hard drive cover and drive module. Disconnect the cable from the drive and reconnect the ribbon cable to the slot for it on the motherboard. Need more...

When some one writes it.

Take out battery. Plug in charger. Does it work now ??? —> replace battery.

Have you tried connecting a voltage meter to it an see if there is much fluctuation?

Hi Mary, Take a look at this video: https://www.youtube.com/watch?v=FTu1g3og... Does that look like your keyboard? Careful with the ribbon cables. Let us know how it goes.

Does computer work with just battery? Charger possibly defective. Alternatively, try taking out battery and plugin charger. Does computer work now? If so battery could be dead or defective. Are there any beep sounds when turning on?

Unplug power supply. Press power button until fans stop. Reset BIOS. You don’t state which HP desktop model. There is usually a jumper to short to clear BIOS to factory default. Often near Front Panel connectors. Plug-in power cable and switch on. How did it go?

The common cause is corruption of drivers. Much, much more common than any hardware defect. This has worked a number of times for me: (1) Completely uninstall graphics drivers. (2) I use DDU (Display Driver Uninstaller) which has a mode for AMD or Nvidia drivers (Majorgeeks.com is a good download site). (3) Shut down and reboot. Re-install latest graphics driver. Personally, I run Ccleaner and Advanced System Care to clean any “stray” settings that may have been corrupted. But DDU alone is probably fine. Let us know how it goes. For other readers. I have had this problem, especially, when I have switched graphics cards.
