Hello, my name is ***** ***** I can help you with your question.
In order to give you the best advise on the matter, I need a bit more general information:
- Can you please provide Full model number of your S3 Acer laptop.
- Back then you tried to enter the BIOS setup screen and the password ***** prompt at you, did you tried to just hit ENTER and see if you had access regardless?
- Do you know if you can access the SAFE MODE in order to try to back up your most needed files??
Please try to reply the best you can to this questions in order to give you the best guidance on what to do next....Thank You!
Based on what you describe, it sounds like the hard drive has failed and needs to be replaced. Hard drives, being mechanical, do tend to make a good deal of noise when they are failing - this could also cause the password ***** come up unexpectedly, since the BIOS password ***** ***** the hard drive password ***** hard drives can be locked. Obviously, you didn't lock it, but when they become corrupt in a certain way, it can cause them to lock. This lock is nearly impossible to overcome in this situation, except through a data recovery service (maybe - even this is questionable). At the very least, the hard drive will need to be replaced. I wish I had better news for you. I'm surprised that the computer repair person didn't mention this.
