Aucun clavier détecté, appuyez sur F1

Good evening,
my son built himself a PC running Windows 8.1 with an Asus B150 Pro D3, Intel i5, and an MSI GTX 950 2GB, which has been working fine until now. About a week ago, he turned on the computer, it asked for a password, and then it went into repair mode, followed by a new screen saying, I quote, "no keyboard detected, press F1 to run set up BIOS," if I remember correctly.
Well, I don’t know much about PCs, but after doing some research online, I found nothing. It’s impossible to access the BIOS since no keyboard is detected. I found a PS2 to USB adapter, still nothing, checked the cables, nothing, removed the battery to reset that infamous BIOS, nothing. I think the solution that could help us move forward would be to access the BIOS, so if anyone has encountered or figured out this type of problem, please help us, before we call a repairman. Thank you, best regards, Vincent.

    Good evening,
    To start, you will follow this process
    unplug the 220v power cord from the tower
    HOLD DOWN the power button for several seconds to drain the capacitors
    remove the BIOS battery
    perform the CLEAR CMOS as indicated in the manual
    put the battery back
    reconnect the power cord
    otherwise, if the motherboard has a PS2 port, do not use an adapter; you must connect a keyboard THAT HAS a PS2 plug
    keep me updated
    Don't forget to mark your post as "resolved" once the issue is fixed. Thank you.

    The purchase of a battery was not necessary because even with the battery removed, a PC starts up... with default settings.
    Otherwise, it would be better to have a "real" PS2 keyboard in your case, to eliminate as many issues as possible... oh yes, imagine if there is a bad connection or something in this adapter... it won't help matters.
    Check with a technician if they can lend you (or sell you for a few euros) a PS2 keyboard; this type of keyboard tends to disappear, and I'm sure the back rooms are full of them.
    Otherwise, the clear CMOS must be done EXACTLY AS I DESCRIBE. (I'm not just talking about removing the battery)
    Best regards

    Hello,
    Thank you for your response. I just got back from work, so I haven't had time to do what you asked me to. What I can tell you is that apart from not having done the CLEAR CMOS, I already removed the battery in the same way you advised.
    Otherwise, my adapter has 2 connectors, one USB side allowing me to plug in my keyboard, and the other PS2 side allowing me to connect to the motherboard. So my question is, is that enough to access the BIOS, or do I really need to consider buying or borrowing a PS2 keyboard?
    Just so you know, I bought a new battery to try again; we’ll see how it goes. I'll keep you posted. Thanks again.

    Re, my current issue is to clear the CMOS on this motherboard, I don't know much about it and the manual isn't very clear. I found a section explaining how to erase the "RTC RAM", they say "use a metal object such as a screwdriver to short the two pins" which I translated as "use a metallic object like a screwdriver to short the two pins," and I admit I'm stuck a bit. And then, reconnect everything while holding DEL during startup to access the BIOS. So I'm going to try to find more info to clear the CMOS on this motherboard and try to make progress. And I'm going to go with my son to try to find a keyboard. Thanks.

    Well, you've already found the trick; you need to use a small metal object and place it on the two pins of the RTC RAM and follow the instructions (the ones you provide)

    So basically, to clear the CMOS, I turn off the computer, unplug it, remove the battery, place my screwdriver on both pins at the same time, separately? Then I wait a bit, put the battery back, replug it, start while holding the delete button and see if it does anything? Sorry, I prefer to be clear in my requests, thanks for your patience anyway.

    But that's very good, at least I know what you're doing.. however, the word "separately" in the post is unnecessary (act as if it doesn't exist)
    Otherwise, it's fine, you hold the screwdriver for 4 or 5 seconds and you do your manipulation as you described

    Don't forget to remove the screwdriver before putting the battery back in.

    Well, apparently it's not working, so I'm going to take the tower to a repair shop and consider buying a PS2 keyboard. I'll keep you updated on the situation. Thank you.
