I cannot unlock the Bios
Vostro 260s
Hi, I have a problem with a machine that I have for days, and is that I can not enter the BIOS, is locked and do not know what the password, and I tried disassembling and changing the pins, then removing the battery from the bios and turn it on I got that it had restarted, however, continues locked.
I tried updating to the latest version of the BIOS which is MS-A10 and it has not worked either, even the processor fan no longer rotates at high revolutions as before and it gets hot, but without accessing the BIOS I can not change its speed.
Can someone help me? Please

Cpu fan rpm issue is probably due to old cmos battery so first try replace cmos battery with a new battery. After that use motherboard CLR cmos jumper to clear cmos settings.
The motherboard password jumper is located next to the lowest PCIex1 slot. Follow instructions printed on motherboard.

I was able to remove the BIOS password and in turn enable AHCI mode.
Well the fan now spins a little faster, however, not like it used to do before.
I will try to do what you say about the battery because as I say this originated from updating the Bios, and while trying to remove the password I removed it for a few minutes and when I put it back on it made 5 beeps and turned on the machine, the beeps were not heard again, but I have not had problems with the time or anything like that

Update: Well I ran the Dell diagnostic test and it gave me these results and as you can see the fan RPM is very low, and I remember it should be like 5000+ at max power.
Also while doing it, it came up error along with about 5 beeps constantly and checking I saw that it is the BIOS battery.
So I should change the battery?
