    I have a K&VT4A-PRO m/b and the CMOS will not keep its settings. I have replaced the battery with 3 other batteries and it still will not keep the settings. Any suggestions?

CMOS batteries really don't charge. They just last anywhere between 3 years and 10 years or more. Voltage on a CMOS battery should be about 3 volts. If the computer is on power from the motherboard keeps the settings on the BIOS. When the computer is off and not powered the CMOS battery holds the settings in the BIOS.

It doesn't It is like a flash light battery.It is only on when the computer is turned off to keep the BIOS settings. Try replacing the battery,if date is not kept.

Charge overnight and the charge runs out without ever being used??


If the battery is good
You have a parisitic draw somewhere:

Switch your Digital Multimeter to DC AMPs. Amps is usually indicated by an "A" on the Multimeter Switch. AC is usually shown as a "~" symbol and DC shown as a "-" symbol. You usually have to move the Multimeter positive lead to a separate socket on the Multimeter. Sometimes there are 2 sockets, a high range and a low range. Always test on the highest setting first. For example: high setting on your multimeter may be 10 Amp. Test on the 10 Amp setting first, then if the current drawn is less than your Multimeter Low setting, move to that setting and keep testing. In my example my Multimeter low setting is 0.3 Amps. Also indicated as 300mA (mA x 1000 = A).

WARNING! Once the multimeter is on Amps do not connect it directly across the battery and do not hit the starter button while testing for current Amps. This will cause the internal fuse in the multimeter to blow! A multimeter set on current is a very low resistance, almost a short circuit and will draw as much current as your battery will supply till something melts. Always plug the Multimeter leads back to volts when you have finished testing to avoid blowing the fuse next time you use your multimeter.

Voltage ReadingTo test for battery drain: Switch everything off on the car. Disconnect just one battery lead. For example disconnect the Positive Battery Lead. Set your Multimeter to Amps as described above. Connect the Positive Multimeter Lead to the Battery Positive terminal. Make sure the Positive Lead you removed from the battery does not touch anything grounded, like the car frame etc…. Connect the Negative Lead from the Multimeter to the Positive Lead you removed from the Battery. You should now see current drain measured in Amps. Move to the lower Amp setting on your multimeter if the current is lower than the setting on the Multimeter Low setting. Start to unplug the wires or fuses around your car and see if the current reading goes to zero. This will point you in the direction of the current thief. You can convert to Power measured in Watts by multiplying it by the Battery Voltage. Power = Volts x Amps 4.2Watts or (12Volts x 0.35Amps).

My makita battery is not taking a charge is it the base or the battery


The most easiest way to be sure is using multimeter. 25290419-3h5pkc2unruv115jj1tsixdi-2-0.jpg
Set your multimeter to highest dc volt. All chargers have output voltage information written on it (Must be written as "output" value or "sec"). Measure charger's output pins (which connects to battery) and be sure measured value matches with output voltage value written on charger label. If it doesn't match each other, buy a new charger and proceed with below part.

Discharge your battery. Once you discharge battery; be sure that there is no charge at all. Charge battery for 15 min. Measure battery power with multimeter again. If there is no charge at your battery, it is dead and you need another battery.

My brand new battery will not hold a charge after a day or two of not riding the bike. Is that normal ? What could be draining my battery?


To find out what's causing the battery to drain, you will need a multimeter set to current measurement. Disconnect the positive battery terminal, and charge the battery fully. Connect the meter leads between the positive battery and the wire you removed. The meter should display some current flowing. Now pull fuses one at a time until the measured current reads zero... That will narrow down the source of the drain for further investigation.

Every time I bot up my pc the dte and time is


hi,
Coin-shaped batteries on most motherboards should be CR2032. Make sure it is properly installed and + is up. IF you have a multimeter or you have a friend who has a multimeter, remove the battery and check the voltage. It should read 3.0 volts when fully charged. If it reads 1.8 volts or higher is probably OK. Be very careful installing and removing coin-shaped batteries. Most of the battery holders i have seen for these batteries are quite fragile and easily broken. I ease these batteries into the holder with the aid of "tweaker" (small screw driver).

here is a video, you can see how to remove the battery or bypass bios password.

You need to press F1 and go into the BIOS to setup and detect everything. You will need to set the date, verify it detects your hard drive and memory, and enable/disable items as you need for your system.

Once it looks good, do a Save and Exit.
