Re: laptop resets date & time every time it starts

You have a small battery inside the laptop on the motherboard (Looks like a watch battery) that has expired. If you replace this battery your problem will disappear.

Your bigger problem is getting to this battery. Usually you can "lift up" the keyboard and get to items like the memory, etc. Check around these areas and see if you can find and replace this battery. Should solve your problem.

Date and time wrong on start up

This indicates the BIOS battery is flat and therefore cannot store the correct date and time in the BIOS. You need to install a new BIOS battery and then go into the BIOS setup to set the Date & Time.

Every time the battery goes dead on my ASUS X83vm and plug in and turn it on, the clock/date reset and the recently replaced network adapter which was the same one maybe different version (Intel Pro 5100 I...

Most people do not realize that a laptop has 2 batteries... the normal 4-6-9 cell battery that we constantly recharge and a smaller (internal) battery to maintain CMOS memory where the clock and other data are stored.

The CMOS battery is normally inexpensive, typically you can find them in a good electronics store or even on ebay. They are easy to change as they typically have a quick disconnect plug. I am not sure where it is located on the ASUS, but look in the memory compartment or the hard drive compartment.

My Acer extensa4420-5963 has been acting funky for the last three/four days. Started out my date and time went haywire. Clock kept losing time as soon as laptop was turned off and reverted to battery. Then...


First of all the RTC (real time clock, BIOS/CMOS) battery has run out. This means the computer cannot keep the date and time when its turned off and disconnected from the mains. You will need to take the laptop to a reputable PC repair store and have them fit you a new CMOS battery.

As for the power on problem, this well could relate to the CMOS battery being drained but also could be a number of different reasons why it won't power on properly.

In my experience laptops that have problems powering on is either to do with the DC adapter on the laptop that has a dry solder point or the power board is failing.

Either way i would take the computer to be looked at.

Date and time never save if I restart the computer.

Yes, the small battery on the motherboard is dead. Turn it over and start unscrewing all the screws, you'll find it.

I do not think you fixed the CMOS battery - (backup battery = CMOS battery) According to the error codes, you have a dead backup battery and the time is not set. Makes sense? 161
(Dead battery.) 1. Go to Checking the Backup Battery
2. Backup battery.
3. System board.
(Time and date were not set.) 1. Set time and date.
2. System board.

hope this will help.
