Hi - looking into buying liquidated company laptops that may need bios resets if they're locked out/restricted.Comment
-
Hello!
Found this site researching a way to fix my laptop (legion 5) after it went down due to a bios chip update (at least I think that's what it is). Not super computer literate but I'm trying to learn more as my passion is gaming, so opportunities come up like this and I dig in to find the problem and learn something along the way since companies arent reliable with customer service anymore. >Greedy bastards. But anyways it's always nice to meet more knowledgeable people that help out of the kindness rather than always asking for an arm and a leg. So thank you in advance.

Hi All,
Its Youtube's fault, I have been getting board repair videos recommended to me all the time for the past year. I also have two laptops that don't work. I figured I would join the gang and learn a new skill. Found this site and joined. I really believe anything can be fixed with the help of the community. Its takes patience.
Have a great day and see you out there.
