Keyboard not working properly

Question

I have had a Dell Inspiron laptop for about 3 years and last year had to have it sent into dell for repairs to the battery and charger. Never had any problems after receiving it back it worked fine and I never had any problems. The last month has been an exception... I now can´t even type a full sentence. It started with the keyboard typing multiple letters when it was only quickly pressed once. I installed a driver program that fixed it for a few days, but then it came back worse. Instead of typing multiple times, now certain keys won't work some of the time. It started with it happening with the A key a few times a day and I would have to spam click it for a few seconds until it would work again. 2 weeks later and the almost 40% of the keys don't work at all anymore, or have to be spammed for 30 seconds until it will work. The shift keys do nothing anymore and I end up using the on-screen keyboard for everything. I have tried changing the drivers and did full factory settings restart but to no avail. Also, my 'About' page lists the device name as DESKTOP-HTT039H, even though it's an Inspiron laptop... and the device ID and Product ID both show nothing in the DELL website search or on google... I'm on windows 10. Please Help! I tried cleaning and that did not help. Thanks!

Attach an external keyboard - if it works OK, the internal keyboard will need to be replaced.

If you need assistance locating the replacement part, post the full model number of the system (i.e., Inspiron 7737, etc.).

Inspiron
