Hi, I have tried with three HDDs, all working with windows installed and without a drive there is still no bios.
Oh, sorry, I misunderstood your issue, haha. Didn't realize this was entirely a bios thing. My bad.
From my understanding, there's a few things that can prevent the BIOS from doing its thing. Here's a couple things you can try:
1. Remove one of the RAM sticks and try booting again. If it doesn't work, swap it with the other RAM stick. If it's only got one stick of RAM and you don't have one you can test it with, I'd leave ordering a new stick of RAM as the last resort.
2. The graphics card or CPU may be bad. If you don't have a removable GPU or CPU, this wont help.
3. If all else fails, the motherboard itself just might be bad. They can be expensive to replace, so keep that in mind. You don't want to spend more fixing this laptop than you would buying a new one!
Good luck, let me know how it goes!
