Question about Compaq Presario 1275 Notebook
I'm helping a friend out with an old Presario 1275. Right now, I get a BIOS error during boot that says the date/time settings are invalid - hit F1 to continue or F10 to fix. If I hit F1, it boots normally, but the date & time are set to 1/1/98 12:00. If I hit F10, I can set the current date & time, but the settings go away the next time it's shut down. In either case, time begins to count up from whenever it's reset, so the internal clock does run. I guessed it was a bad CMOS battery and replaced that. It still gives the same error message! I pulled the new CMOS battery out & tested the voltage, and it's right on - the new battery is good. I made sure I reinstalled it with the correct polarities. Now what?
Tips for a great answer:
You should make sure that all of the BIOS settings in the system are correct, by rebooting the system, going into BIOS setup and double-checking all the values hopefully against a recent
If you have reset the CMOS memory you need to go into the BIOS setup screen and reconfigure the BIOS. To do that you need to press a key while the computer is booting. Usually F2 but can be other keys. It should tell you on the bottom of the first screen which key to press to enter BIOS setup.
If you don't know the settings the should be one for optimal defaults - use that one. You will also need to reset the time and date.
Save, Exit and re-boot and everything should then work.
This error is not the same as a CMOS Checksum Error, which refers to corrupted values of the CMOS settings, the ones you set through the BIOS setup program. This error means the contents of the BIOS code itself are damaged.
During the boot process you will see on the screen a certain key to press to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
You will also need to set the time and date
In the main or system setup screen you should be able to see the date and time Using your arrow keys navigate to the date and change the date. Once highlighted on the month, day, or year, press your arrow keys or your page up / page down keys to change the date.
hope this helps you
