    And you have a new battery?  You can purchase new BIOS chips and change out the chip itself.

Please make sure that you change the onboard battery as it is the problem for making your bios lose the time. Also note that later on it might lose other settings such as hard drive settings etc.

To change your battery

1. Please refer to the manufacturer's manual of the motherboard ... you can download a pdf version of the manual from the website of the motherboard.

2. Locate the battery and make sure it's powered off and the power chord is out of the Power supply.

3. Remove the battery using a delicate plastic lever of the size of a tiny screw driver. I said plastic so you don't short circuit anything in the process.

4. Do not touch anywhere on the motherboard with your bare hand due to static electricity.

5. replace the battery with new one

6. Go to CMOS and change settings and save them

Hope this fixya was of help to you :)

This is usually Del, F2, or F12.
The key, however differs with each machine.
It should be stated on the screen for a very short time which key is the setup key
You can change the bios settings by using the ARROW KEYS select it press enter and exit then press the F10 key to save to cmos and restart
If your not sure or you have made any wrong bios changes you can set failsafe or optimised defaults

Before flashing the BIOS do a search on BIOS flash and read the caveats.
Backup your current BIOS and only flash if it is absolutely necessary!!
If the computer vendor is unknown or unavailable, try to identify the motherboard vendor and model number if you can, BIOS updates are specifically associated with motherboard versions:

How to clear and load cmos default bios parameter for a Aspire 5630 modle no. BL50?

Two methods;

1) Remove ALL power to the laptop, except the CMOS battery.
Remove the AC adapter (Charger) and Battery.

2) Press the Power On button in, and hold it in for a full count of FIVE seconds.
Let go of the Power On button.
Do this procedure TWO more times. (Important)

This procedure clears CMOS Error Codes, and resets BIOS Setup back to the factory default settings.
Reinstall power. Install the Battery FIRST, then the AC adapter.

Go into BIOS Setup.

As soon as you press the Power On button, start tapping in 2 second intervals, on three keys at the SAME TIME.

Press all 3 keys at the same time.

Hold the Power On button down for 10 seconds to turn the laptop off.
Wait 30 seconds, turn the laptop back on.

As soon as you press the Power On button start tapping on the F2 key.
(Tap in 2 second intervals)

When in BIOS Setup look at the main page, and towards the bottom.
Here you will see an F key listed that when pressed, will revert BIOS Setup back to the factory default settings. (Generally F6)

C) Remove all power from the laptop.
Lay a towel on a table, and lay the laptop upside down on the towel.

Open the Memory Compartment Panel, and remove all ram memory modules. ('Stick')
Located towards the middle of the ram memory compartment is the J3 jumper.
There is a J3 with a square line going around it.

This jumper is used to clear any settings made, and will go straight back to all factory default settings.
In otherwords if someone set a BIOS password, the J3 jumper will remove it.
Factory setting for BIOS password is no password.

My pc doesn't want to boot up. this happend after i updated my bios. what might be the priblem & what's the solution?

> this happened after I updated [the] BIOS

After the 'flashing', did you enter BIOS SETUP, and then use 'Load BIOS Defaults' ?

After that, did you use 'AUTO DETECT DISK DRIVES' ?
If so, were your disk-drive and your CD-drive detected properly?

Hopefully, you updated with the correct BIOS that is specific to exactly your motherboard.

Some motherboards have the capability to 'flash' the BIOS even when a recent BIOS-update did not fully complete -- check the manual that came with the motherboard for the exact key-sequence to activate this 'emergency' BIOS-update.

If you can remove the BIOS chip from the motherboard, and you have your own EEPROM 'writer', you can update the chip while it's mounted on this EEPROM 'writer', and then re-install the BIOS chip onto the motherboard.

Is there a way to repair a bios after a failed update

Recovering a damaged BIOS is simply a matter of replacing the missing or damaged code contained within the CMOS or EEPROM. This is not an easy task and some computer knowledge is strongly advised if attempting this.

You can solve the problem by removing the Lithium battery on the main board, wait a few minutes, then put the battery back in and reboot.
The BIOS will detect that there are no BIOS settings, and use some default settings. NOTE...It will tell you that some settings are erratic, but at least you are now able to press DEL to enter BIOS setup.

After entering setup you will be asked to choose either "Load default fail safe" or "Load optimal settings". The latter will work most of the time. Save these settings, reboot and see whether your attempts were successful. I've seen this type of boot failure on many machines and in case of bios update failure, this has worked 90% of the time.
If, by chance it does not work at once, try to keep the battery out a little longer, and short-circuit the + and - pins of the battery socket.

When you do get some life back into your PC don't forget to check that you indeed flashed the correct BIOS version that belongs to your motherboard. Maybe you flashed just a slightly different version. If so, find the correct BIOS version even if your PC seems to work after following the above steps, find the correct BIOS version and reflash.

Everytime we boot up our computer it says press f1 to do something and f2 to enter setup mode?

generally an indication that something is wrong in the system setup. Press F2 and enter setup, check the time and date settings and the system event log (If BIOS has one) for incorrect settings, also check and see if the BIOS shows a hard drive installed.

If time and are wrong, set them to correct and save settings. If system keeps losing time and date after power is removed, then the backup battery may need to be replaced.

If HDD is not detected, then reseat it. If still not detected replace it.

I did BIOS flash update on my ASUS P5WD2 Premium motherboard. The reason was to fix boot message: “CPU load error. Press f1 to continue” I have two questions: 1) immediately after...

Install the BIOS Flash update, one by one. Like for example 1.0, 2.0 or 3.0.
And if still the problem consist. I think its not your BIOS problem.
Clear the BIOS by disable the JUMPER Setting.
And one last thing change the LITHIUM BATTERY(CR2032) a new one.

If you got the problem again, put a comment so that we can easy understand what is the problem with your MB.

If i am helpful, please rate me.
Thank you very much.

Updated bios

Can you still access the bios setup page? It could be a flash gone wrong. Flashing could have failed, or wrong flash, or other reason. You can try flashing again, but tell me step by step how the problem goes.
