Actually, the CMOS batteries generally used on notebook PCs are of CR 2035 model. The maximum voltage rating provided by manufacturer is 3V. However, in real time it may vary from 2.6v to 3.0v. Hence, there is no need to worry about 2.7V unless it drops to less than 1.5V.

I have a Samsung sde3000n. When I came home the hardrive was clicking so I restarted it and the cmos battery. Now 3 lights flash on the motherboard and it just clicks. Please help

Replace the coin cell battery and reboot. You'll have to reset the time and date. Your power supply may be losing critical voltages too. You can check it with a volt meter. Look for 3.3 volts, 5 volts and 12 volts on the power connector of the hard drive.

Motherboard, the inverter output voltage

Inverter output can vary, but anything greater than 150 volts with a high impedance meter (with a capacity of 2000 volts) can be considered good. The meter loads the circuit by itself and normally the RMS voltage that most meters register is lower than the peak to peak voltage of the circuit. If a scope is used, use a 10:1 reduction probe, and your voltages can be anywhere from 300 volts to 1200 volts with 650 to 750 being the normally accepted good range. Where your brightness control is set will have direct impact on the voltage you see.

Got given a CB radio.. from a trucker... im in the [UK] wanting to put it in my car.. accept the voltage difference... a truck's voltage is about 24-volt's.. compared to a car.. only being 12...

I don't think there is a in accessories. The 24 volt truck systems are Cranking and Lighting. Either way you have no risk at trying the lower 12 volt car electrical. The problem is when you reverse polarity.

I need to ask a question about a window unit in regards to what is the highest acceptable voltage. Based on a 230 volt template rating what voltage variance am I allowed. I am reading 250 volts on the...

no,this is ok,because moitors are voltage based lower in voltage than other appliances w/o motors,a 230 volt motor will operate fine at +/- 10% voltage as in 230 + 23 volts higher = 253volts and visa-versa 230volts - 23 volts + 207 volts, if your losing units,have your power supplier check the incoming neutral connection to the home,then have them install a temporary power quality monitor on the line to check for "power-Spikes/Surges" especially if your near any type of commercial setting with 3 phase power as these large facilities create lots of power spikes during operation of their equipment

Will not run only on gas but will not cool

If it works on gas and NOT electricity then the heating element is not getting power or the heating element is open. The heating element is located on the tubing just aft of where the pilot flame is on the bottom of the copper tube. You should check for power to the heating element and with power off perfom a continuity check on the element. I really do not at this time think you have a heating element problem.

There is a 120VAV element a AND a 12VDC element. The chances of both of these failing at the same time is pretty slim.

There is a note in the manual:
If the gas only pushbutton is depressed the
lamp will illuminate green and the refrigerator
will only operate on the LP gas mode, even if q
120 or 12 volts are available.

Another significant change in the third
generation A.E.S. system is how the 12 volt
heating element mode operates. As with the
first and second generation series, the 12 volt
heating element circuit is energized by the
ignition lock terminal. This terminal receives
its DC voltage from a wire that runs from the
run side of the vehicle’s ignition switch to the
refrigerator’s ignition lock terminal. This
allows the 12 volt heating element to be
energized only when the RV is traveling down
the road.
When the ignition lock terminal is energized
by the ignition key, the printed circuit board
must see at least 13.3 volts DC for a period of
40 seconds before the system will activate the
12 volt DC heating element.
If 13.3 volts is not achieved in this time frame,
the electronics will light the LP gas burner and
the refrigerator will operate on the LP gas
LOWER THAN 13.3 V.D.C. =LP Operation

If the battery voltage remains low after the
delay cycle, the automatic controls will light
the refrigerator on the LP gas mode and stay
on the gas mode until the printed circuit board
sees approximately 13.3 volts DC to the
terminal block.

For proper cooling on the AC mode, the AC
voltage to the refrigerator should not vary
more than 10 percent from the voltage rating
on the heating element. Heating elements used
in Dometic refrigerators could have a rated
voltage of 110 volts, 115 volts or 120 volts AC.
Because of this, the power requirements for
each differently rated heating element will
vary. For example, if a heating element is
rated for 100 volts, the acceptable power range
would be between 99 to 121 volts AC. If an
element is rated for 115 volts, the acceptable
power range would be between 103.5 to 126.5
volts AC. If the heater is rated for 120 volts,
the acceptable AC power range would be
between 108 to 132 volts AC.

The unit to operate on either AC or DC must have 13.3 volts to the unit. I think this is where your problem lies in that the battery voltage is less than 13.3 VDC

If all of that checks good just repsond here and I will help you. There is still more that can be checked.

Thanks for choosing FixYa.

Dell dimension 5510 it will not turn on, no

1/10th a volt? Nope.

Bypass the Power On switch. See if you have a bad switch first.

Then test the power supply. If the power supply comes on by bypassing the Power On switch, I'll bet you have a weak 12 volt voltage power rail.

1) Yellow wires are 12 Volts
2) Red wires are 5 Volts
3) Orange wires are 3.3 Volts
4) ANY Black wire is a Ground wire

They do sell power supply voltage testers, should you not wish to use a multimeter set at DC volts.
(0 - 50 Volt scale)

I prefer a multimeter.

A) ALL the light use less than 1 Watt
B) EACH fan uses 2 to 3 Watts

C) A typical Processor uses 55 to 125 WATTS.

You have to turn the power supply on, by jumping the Soft Power On wire to any ground wire.

This is also the way to bypass the Power On switch, to see if the switch is bad.

Do you wish to proceed?

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.
