why do I have to set the time every time when I turn on the computer?

Answer 1

It sounds like your CMOS battery may not be working properly. You can buy a replacement.

Answer 2

Have anyone ever wonder why the clock is on time even when the computer is turned off and no electricity getting in? That's because a battery takes over when the computer is off. This battery doesn't last for life and needs to be changed every so often. It usually lasts about 10 years, but could give up sooner or later than that. Clock fading, Clock blinking and not keeping time are all signs it needs to be changed.

Answer 3

Normally the time is maintained by having a battery operated clock running on your computer motherboard. When switched on, the clock runs from the normal power supply.

From what you say, it would appear that this battery operated clock is not running.

This is usually down to a flat battery.

There is another thing that can cause the wrong time to be displayed. The time zone may be set to the wrong zone and the internet time sync might be set. Here you coumputer pulls the time from a time server, interprets it according to the time zone set to display what it understands as the right time (for the zone selected).

Answer 4

That usually means the CMOS battery is dead. The CMOS battery is a little battery that sits on your computers motherboard. It's responsible for making sure your computer's date and time are remembered when your computer is turned off. The batteries are easily replaceable. You can find your CMOS battery by opening up your computer's case and looking at the motherboard. Most resemble a watch battery but some come in battery packs. You can pick up another CMOS battery at a variety of different places. Retail stores like Wal-Mart sometimes sell them as do places like Radio Shack and Circuit City but sometimes they can be found at your local hardware store (That's where I picked up mine when I needed a replacement).

Answer 5

You have a dead motherboard battery. Open the case and take a look. If it is a button-type battery just take it out & go to an electronics store and match it with a new one. If it is a round one that looks a bit like a condensor that is soldered into the mobo just pick up a "battery eliminator" that uses AA batteries. You will have to move a jumper on the mobo to turn off the soldered in one.

Answer 6

Sounds like your system battery is dead. Replace it and it should be fine. A PC should be able to be turned off, unplugged and taken to bits, reassembled and switched back on, and still have the correct date and time. You will find the battery on your motherboard somewhere. If this isn't the problem then I can't think what else is i'm afraid!

Answer 7

How old is your computer? It sounds like your BIOS clock's battery is dead. If you are comfortable doing so, open your case and you will find a small battery on your motherboard, replacing this should sort it out. Failing that I've no idea!

Answer 8

Looks like your CMOS battery needs replacing.
It's a bit like a large wrist-watch battery that sits on your motherboard which provides just enough power to 'remember' stuff like this. When it begins to 'forget' the info, the battery is out!

Answer 9

Because your battery has failed you nit, replace it, your BIOS is where the date and time are stored, so once you have set it it's fine while the PC is turned on but without battery back up no sooner you turn the PC off your BIOS info is lost.

Answer 10

it may be that your computer is not syncing to the correct time zone. if you double click where your time shows and click on time zone. make sure that you have it on the correct time zone and also there should be a third tab where you can sync to the right time. the mother board that some of the people are referring to is your CMOS battery. that is what keeps your right time. here is the link to what a CMOS battery looks like.
