Main Bios Checksum Error!!!


Take notes of the BIOS settings of your computer for use after replacing the CMOS battery.

To access the computer's BIOS, restart your computer and press the "F 10" function key during the restarting process.


The BIOS configuration panel will then open and you can write the specific settings for your computer down to use for BIOS configuration after replacing the battery.


Turn off your computer and remove the power cable and if installed, battery.

Remove the computer hatch which will vary in method depending on the brand and model of computer you have.


On some motherboards cmos batteries are soldered in


Locate the CMOS battery on the motherboard.

The more popular model of CMOS battery used is annotated with a CR2032 label and is a round shaped button.


Firmly remove the CMOS battery from the motherboard.

Align the new CMOS battery with the positive side orientated towards you and insert into the mother board.


Restore the power cables to your computer and restart the PC.

During the restarting process, depress the "F10" function key to enter the BIOS setup screen.


Update the date in the BIOS and change the BIOS settings to match those you recorded in step one.


After the settings are updated, select the "Save and Quit" menu option and restart your computer to finish the CMOS battery replacement.


hope this helps

As i turned on the monitor the screen shows CMOS WRONG PRESS F1 TO SETUP PRESS F2 TO LAOD DEFAULT VALUE


hi,
first of all check the main battery back of ur machine by unplugging from the mains power supply. if machine shuts off, then u have to replace the battery.and then set the date time etc by pressing F1. and then save it and exit set up. next it will not ask for F1 or F2.

if the main back up battery is ok, then another possibility is the CMOS backup battery of ur machine have some problem. that's why it loosed all the seted parameters. then u have to replace the CMOS battery of ur machine. normally 3V battery. then set the date time etc by pressing F1. and then save it and exit set up. next it will not ask for F1 or F2.
ok

The cmos always resets everytime i do a cold boot after 8 hours. i always needed to set the corect date and time


I'm thinking you need a new CMOS battery.
The battery number should be a 2032. It's on your motherboard and is a little smaller than a US quarter

Unable to save date in m/b bios


make sure your using new cmos battery not yet been use and then set date in your bios and save it after finish.
still doesn't work?
try update your cmos that migth be the problem note! remember always take care of the risk on updating flashing cmos on power interuption never power off if still flashing. or if you update and flush it before it might be a bad flash of your cmos try bring it up to early state or restore your backup cmos firmware or download it to its main manufacture

PC start directly


Explain what you mean when you say 'when i open the pc from main switch'.
Also, something you should try is updating the CMOS, or in other words flashing the BIOS firmware. Go to your motherboards manufacturers website and see if there are any BIOS updates for it.

Cmos battery dead - needs to be replaced


Sounds like you need to change the CMOS battery, the time being wrong everytime you boot is a good sign but also it losing its settings in bios is also another sign

Hi, can I operate the A 70 on mains power without a battery


Your battery will not charge until it reaches a lower limit of charge.
Whilst in the Laptop and using mains power your battery acts like a UPS and is available soon as you lose power.
The battery life will not be degraded or improved, removing it whilst plugged into mains.
When using Laptop om=n mains the battery is always there in case you lose power or somehow the lead gets pulled out inadvertantly, so you will not lose work.
I use a laptop all the time for work just got a new Latitude D630. The battery in my old lappy is still good for 2hrs+ and never been removed.
80% of its life was on mains.
Hope this helps.

Always reverts to 1900


This indicates that the cmos battery is dead and needs replaced. The cmos is located under the main battery, it's in a yellow or greenish pouch with two wires leading to a connector. You'll have to remove the keyboard in order to get to the connector. Replacing the cmos will correct the time and date problem, if it doesn't fix the battery problem, you may need to go to IBM's support site and download the power management driver.

Had the same problem with My Compaq M700 No Boot Or Post. Battery Light Flashes 8 Times, Have to Wait 24 to 48 hrs sometimes longer to get Laptop to Start. Tryed the DC Converter Board Change No Difference same Problem. Noticed When Laptop Did Start Clock Time Was always a Little Off 2-4 Hours sometimes more. So Figure CMOS Problem With Time Issues. Read About Battery Memory Transitor Voltage spike Detection Issues Corrected With Newer Bios Flash at HP Supports. So I Flashed Bios With Latest 686h. During the First Boot After Reflash Battery LED Did flash No Start, After pushing the power button again it Started. And has Every since.So Far Laptop Now Boots Everytime and CMOS Checksum Seems To Keep Time Correct In Windows. The Bios Flash Corrects a Voltage Spike Detecting Transistor In The Charging Circuit. During First Start after flash Bios will run system test on the charging system and Correct CMOS. Worked for Me Hope this Helps a Few.
