I get a screen on my laptop when I boot up. At the bottom it says: Please enter setup to recover BIOS settings CMOS date/time not set
Press F1 to run setup Press F2 to load default values and continue. I'm running window XP Home on this laptop. The laptop is an Asus Eee PC. Not sure what to do here??

If you click F2 does the system then boot up correctly till the next time you restart?
If so you most likely have a failing cmos battery that needs to be replaced.
On a laptop that battery would be located under the hd most likely and looks like the picture below. You can buy them at most electronics store or even a jewelry store may have them.

The battery that keeps your CMOS data (bios settings, date, time etc.) is probably dead so each time your laptop is not connected to an ac power you loose all your data.

You need to replace the small battery (similar to a watch battery) inside your laptop.

If putting a new battery and saving your BIOS data does not fix your problem then you might have a CMOS chipset problem

It boots up when I press F2, however the time is not correct. I also noticed that when I use the power cord and open the laptop the power light is on. Before I had to press the power button to power up and boot.

This laptop is maybe over a year old. Is this common for the battery to fail?

They do eventually wear out but it is uncommon for them to go out in a year. Is there still a warranty in effect for the laptop?
If so you might see about having it replaced under the warranty.
The cost of the battery is less then 5.00 USD and is not that hard to replace with a little care.

I'll check to see if it's still under warranty, but it seems pretty straight forward to replace. After I switch the battery..do I need to change anything with the time setting?

Yes you will need to go into the bios and reset up the time and date. Make sure to save before you exit.

I reset the time and date in BIOS, but still get the screen. Now it doesn't say that there is a time and date problem. The date and time are ok. Should I just re-format it?

Go back into the bios and click on Load Defaults and then Save and Exit
Let me know if the message still comes up then. :D

Did you go into the bios and load defaults and then save and exit?
Any errors on bootup?
