Re: NEC Versa M320 cmos problem!

I tested this camera for a client. I didn’t have the light running for more than 15 minutes. The battery lasted approximately 6 hours before recharging. The LCD, however, had a few dead pixels - never saw this before. Tried returning for exchange and had to put up quite a fight. Anyone else seen this?

System unit or power supply?

The computer power supply may have failed. Do you get the "post beep"?

If not- remove the BIOS battery, move the jumper to "Clear BIOS" . Insert BIOS battery, and try to boot. Put jumper back to normal position and try boot again. If you do not get the post beep, swap power supply for a known good one, and try boot again. If it still does not boot and give you a post beep, look to see if there is a removable BIOS chip- pop it out and put it back, this will clean the terminals. Go through and reset BIOS, as above, and try boot. If the system is functional, it should now boot up, but prompt for you to run the setup program.

If it does not boot, the problem is relating to motherboard/processor.

Changing the cmos battery in a laptop

Possible, depends on exact model of your laptop. They tend to use same kind of holders/cells as desktops do. Why do you think you have to change the battery in the laptop? be advised, that erratic system behavior can also mean a dozen other things. Sometimes, the cell holder itself gets damaged and needs repair. Also, many laptops do not reset their bios passwords even if the cell is removed.

The Cmos or (RTC) battery lives with the hard drive on these models. Simply turn the laptop over and release the hard drive, the battery is in the same compartment.

How to remove cmos/bios password ?

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

Where the @@@@@ is Cmos battery????????

Many laptops use a small, 3 cell rechargable battery. Look for something that looks like a small tube lying horizontally. It will be soldered in if that type. One source for replacements, is
If a replaceable coin cell, then it will be like a watch batter, and quite visible.

Apple G4 notebook CMOS battery replacement

If you turn the Laptop upside down (making sure that the laptop is not turned on at the time!) you will see some compartment panels that can be removed. Undo the screws to these and you will see the CMOS battery in one of them. Have a replacement battery ready to insert...remove the old battery and insert the new one. Put the cover back on and your done! Hope this helps.

Laptop does not take any mains power

Try clearing your CMOS. This is done by removing battery and mains power, lifting the speaker cover off and then look under the keyboard. Unscrew panel where keyboard ribbon enters, you should now see your RAM & BIOS chip. Disconnect ribbon next to BIOS chip and reconnect, that should clear your CMOS.
