So my Sister in-law had some virus problems and took her laptop to me. After receiving it, I removed some obvious adware and ran Malwarebytes. It found a quite a few items and quite a few registry problems. So I did a Fix All solution. After the "quarantine" I decided to restart the laptop and I noticed the keyboard on the laptop wouldn't work. None of the buttons. But after some force shut downs I noticed the keyboard works in BIOS settings, like to select Safe Mode or to Run Windows normally. but as soon as Windows boots up, it doesn't work. I thought to myself oh crap, maybe I can do a system restore and, that still didn't really fix my problem, it just technically removed Malwarebytes but still had the folder in, my programs.
I went through Device Manager, and it doesn't recognize that anything is wrong. I've uninstalled the HID keyboard in hopes to re-install it in device manager, and it just reappeared. I've been using a spare USB keyboard for desktops to use the keyboard. I did notice that if I leave the laptop on long enough (3-5 hours) the laptop keyboard will finally work. But I'm not about to tell her that she can use her keyboard 4 -5 hours after boot up. I feel stumped on this one unless I'm overlooking something simple.
I've removed malware and a few viruses in hopes one of them was preventing keyboard use. But still nothing. And nothing came out of a google search. Only if a few keys weren't working
The laptop specs are:
Dell Inspiron 5520
Windows 7 64-bit SP1
Intel Core i5-3210M
Intel HD Graphics 4000
1TB HDD and 8GB RAM
Let me know if I need to add anything else to my details.
By the way hello again, I had a bleeping computer account years ago. So I thought I'd get a new one!
