    Yes, I understand but unfortunately there is a password on the bios. However the person who sold me this computer cannot remember what the password is.

    Generally, laptops and tablets do not have jumpers. To get to the bios, some tablets will give you a chance while booting, or you must connect a keyboard and press a certain key to get to the bios.

Bios password


This information is intended for experienced users. It is not intended for basic users, hackers, or computer thieves. Please do not try any of following procedures if you are not familiar with computer hardware. I'll not be responsible for the use or misuse of this information, including personal injury, loss of data or hardware damage. So use it at your own risk.

A. By Using the Motherboard Jumper:

In most motherboards CMOS battery is soldered, which makes it difficult to remove the battery. In this case we use another method.

Almost all motherboards contain a jumper that can clear all CMOS settings along with the BIOS password. The location of this jumper varies depending upon the motherboard brand. You should read your motherboard manual to check its location. If you don't have the manual then look for the jumpers near the CMOS battery. Most of the manufacturer label the jumper as CLR, CLEAR, CLEAR CMOS, etc.

When you find the jumper, look carefully. There will be 3 pins and the jumper will be joining the center pin to either left or right pin. What you need to do, is remove the jumper and join the center pin to the opposite pin. e.g. if the jumper joins center pin to left pin, then remove it and join center pin to right pin. Now wait for a few seconds and then again remove the jumper and join the center pin to left pin.

Make sure to turn the PC off before opening the cabinet and resetting the jumper.



B. By Using Software:


I have found that BIOS/CMOS Password Recovery Tool is the most effective.:
BIOS/CMOS Password Recovery Tool is a program that works instantly to remove any lost or forgotten BIOS/CMOS password. Simply boot your PC to DOS and execute the program, and get access to forgotten BIOS/CMOS passwords in just seconds

Want to reinstall OS on compaq tc4200. don't have passwords..


If the BIOS password is set, you'll need to return the device to HP/Compaq to get that reset. Only other option I can think of would be to whip the hard disk out and see if it'll boot from a CD at that point. If that is the case, you could theoretically put the drive in another PC, wipe it completely and then reinstall it. The machine will try to boot from HDD, fail and then boot from CD next.

Password problems on a Toshiba Protege m200 laptop


If you cannot access the machine after if has been powered up, it is still possible to get past the BIOS password.

  1. The BIOS password is stored in CMOS memory that is maintained while the PC is powered off by a small battery, which is attached to the motherboard. If you remove this battery, all CMOS information (including the BIOS password) will be lost. You will need to re-enter the correct CMOS setup information to use the machine. The machines owner or user will most likely be alarmed when it is discovered that the BIOS password has been deleted.
  2. On some motherboards, the battery is soldered to the motherboard, making it difficult to remove. If this is the case, you have another alternative. Somewhere on the motherboard you should find a jumper that will clear the BIOS password.
  3. If you have the motherboard documentation, you will know where that jumper is. If not, the jumper may be labeled on the motherboard. If you are not fortunate enough for either of these to be the case, you may be able to guess which jumper is the correct jumper.
  4. This jumper is usually standing alone near the battery. If you cannot locate this jumper, you might short both of the points where the battery connects to the motherboard.
If all else fails, you may have to clear the BIOS password by resetting the RTC (Real Time Clock) IC (Integrated Circuit) on your motherboard.
Many RTC's require an external battery. If your RTC is one of this type, you can clear the BIOS password just by unsocketing the RTC and reseating it.

Good luck and more power

Reset the bios on a compaq tc4200


I haven't tried it yet, but according to HP's "Maintenance and Service Guide" (Available in PDF from their Support website) you have to completely break down the computer, remove the mainboard and the CMOS battery should be located on its underside. Remove it for five minutes, replace and reassemble EXCEPT FOR BATTERY and turn it on under AC power only. I just purchased one that needs reset, but haven't received it yet, so I cannot attest to its effectiveness except that this is deirect from HP. Hope it helps!
