My computer's internal clock keeps resetting itself to 12:01 01/01/2001. How do I fix it?

Question

I'm running Windows XP and every time I reset the clock/calendar (at the lower right hand corner), a few days later, it resets to 12:01 01/01/2001. Is there an internal battery I need to change or does my computer have a virus?

Answer 1

There's a dead battery on the motherboard. It needs to be replaced. When that battery dies, the computer will lose its date settings when unplugged, and may start to lose other settings in the future.

Answer 2

Your motherboard will also have a battery. that's uncomplicated to discover and replace, that's in ordinary terms a small coin type (regularly CR2032) or watch type battery. some batteries slide out, others could desire to be unclipped, and often times there's a screw to be undone. Disconnect the computing gadget from the mains capacity, open up the area of the casing, and the two use an anti-static wrist or ankle strap or touch an earthed (US=grounded) bare metallic merchandise usually as you artwork to verify which you do not fry any circuits with a discharge of static electrical energy. The interest could take approximately 5 minutes, yet regularly there are different leads and connectors in the way which you will could desire to disconnect to get at it. in case you do not sense confident then ask a knowledgeable buddy to help, it rather is an uncomplicated interest as quickly as you have been shown a thank you to do it.

Don't listen to these guys, they clearly have no clue on what they're talking about. I am a developer at Microsoft so I know a thing or two about computers. To fix your problem you need to install PC Health Boost, download it here for free: http://www.healthboostpc.com

It's very light and it's the only antivirus/cleaner with a 99.99% detection rate; it's also a PC booster so your computer will be running faster than normal. Install it, hit run and problem solved. It shouldn't take you more than 5 minutes.

Answer 4

Yes, the above two are correct. It is your internal battery. It is mounted on the motherboard. Just be careful and make sure the computer is unplugged and you don't have any static electricity on you. And make sure you get the correct battery or an explosion may occur.

Answer 5

You need to replace the internal battery. Look inside for a small, round battery, about the size of a quarter. That is what you need to replace. Go to a computer store or RadioShack and ask for CR2032 coin-battery (or just show them yours).

Answer 6

Double-click the digital time display in the task bar.

In the Date/Time Properties window, select the Time Zone tab.
Click the checkbox beside Automatically adjust clock
As long as the box is checked, future daylight saving time changes will occur automatically

A computer's system clock resides on the motherboard. It sends out a signal to all other computer components in rhythm, like a metronome

If a system clock runs at 100MHz, that means there are 100 million clock cycles in one second. Every action in the computer is timed by these clock cycles, and every action takes a certain number of clock cycles to perform

It's possible for the CPU and other devices to run faster or slower than the system clock. Components of different speeds simply require a multiplication or division factor to synchronize them

Try replacing the Time & Date control panel file (Timedate.cpl) in the
Windows\System folder, with a fresh copy from your Windows CD or the .cab file
location on your hard drive.

A computer's system clock resides on the motherboard. It sends out a signal to all other computer components in rhythm
Each wave in this signal measures one clock cycle. If a system clock runs at 100MHz, that means there are 100 million clock cycles in one second. Every action in the computer is timed by these clock cycles, and every action takes a certain number of clock cycles to perform. When processing a memory request, for example, the memory controller can report to the processor that the data requested will arrive in six clock cycles.

It's possible for the CPU and other devices to run faster or slower than the system clock. Components of different speeds simply require a multiplication or division factor to synchronize them. For example, when a 100MHz system clock interacts with a 400MHz CPU, each device understands that every system clock cycle is equal to four clock cycles on the CPU; they use a factor of four to synchronize their actions.

Many people assume that the speed of the processor is the speed of the computer. But most of the time, the system bus and other components

Answer 7

Replace the CMOS battery on the motherboard. When it gets weaker you won't be able to even boot.

Answer 8

Yes, the former....
