Having problems with your Compaq Presario 1275 Notebook ?

I've got a compaq presario 1245 laptop. On booting it gives me a black screen with "Error 0270 Real Time Clock Error" I can get into the Setup and boot screens (F1 & F10) but any changes (reset date/time etc, boot from C drive rather than floppy disk) are lost when I save and exit. do I need to replace the CMOS battery - if so where is it and what battery do I need to buy?


Answers :

Hi
\015\012you will need to open your computer and look inside. if you are not sure take to a repair centre, the battery is on the motherboard, thats why you need to take really if you are going to be doing it. But i would advised to get a IT guy to do it for you. once its taken out you need to replace it with a new one.
