While removing the onboard battery and disconnecting all power for 5 minutes may clear the bios, some passwords are written into NvRam (non volitile Ram). This may require you to move some jumpers. Try this.
It may be necessary, on occasion, to clear the CMOS settings. When the CMOS is cleared, all information stored in the CMOS is replaced by default data, which means that all of the configuration information, such as hard drive types and I/O port setup, is cleared, including the password. Use the following procedure to clear CMOS:
Power down the computer.
Remove the left cover of the computer.
Wearing an anti-static wristband grounded to the chassis, remove the jumper from pins 1 - 2 of the Clear CMOS jumper block (JP15) and install it on pins 2 - 3.
Remove the jumper from pins 2 - 3 of the Clear CMOS jumper block (JP15) and install it on pins 1 - 2. (NOTE: Some earlier systems will power up as soon as the jumper is removed from pins 1-2. Later versions of the BIOS change this, 6.00.10 or later.)
Reinstall the cover and power up the computer.
Run the BIOS Setup program to reconfigure the system.
NVRAM should be your BIOS, if that's not found
you've got something wrong with your motherboard. I don't think it's a dead CMOS
battery but you could try changing it, dead CMOS batteries usually say bad
edit: try removing any hardware you don't need for the computer
to boot then if it works, add them back one by one
This is what i do whenever someone asks me to remove their PC from power saving mode.
Try clearing the NVRAM as follows: -Turn off the computer -Disconnect the monitor. -Unplug the computer. -Take out the video card. -Remove the CMOS battery for a couple of minutes. -Insert the battery. -Connect the video card and monitor. -Turn on computer.
1. check the RAM is seated 2. Try any other RAM 3. still the same problem check the video or graphics card , if any 4. if no graphics card and problem stiil changing it clear your CMOS by removing battery 5. if its new system then, remove battery, then take a small wire piece and short the positive and negative of the battery socket, then only CMOS is cleared 6. still problem , check the processor heat sink 7. still problem then suggesting checking motherboard and processor
Please post your feedback and Vote if the problem resolved as per your satisfaction.
if you are referring to the round battery on the motherboard, it controls the cmos settings remove this and your PC will not boot. yet clearing your cmos may help. look for the lil jumpers usually located near that battery and change them to reset, power on let boot then power down. then place them in the original slot.
Hi there. Try clearing the cmos . move the plastic jumper the alternative position,
power the pc up (Nothing will happen if you have it correct, then put
it back in its original position and try to boot the machine again, password should be removed. Good luck and thanks for using Fixya!!
This message "Checking NVRam" is part of the BIOS/CMOS POST even before Windows loads up.
Offhand two things you can try:
1. Do a CMOS reset by temporarily moving the jumper near the battery to the opposite pair or by removing the Lithium battery for a couple of minutes or as prescribed by your motherboard's user manual;
2. If #1 is a no go, perhaps you should consider flashing your BIOS.
If neither works out, it is possible that you have a hardware/motherboard problem and would require replacement.
Hope this be of some help/idea. Post back with your motherboard brand/model, how things turn up or should you need further information.
Good luck and kind regards.
