The computer store would replace the battery and possibly reset the CMOS jumper.Remember to adjust your time and date in BIOS before you boot.It's probably not the battery---

There is no battery. My online research has turned up that this model laptop is designed without a cmos battery. Aaand i WOULD adjust the date and time, but i cant even get into the bios. I turn it on, it beeps 3-3-1....3-3-1....3-3-1.... etc and thats it. Nothing on the screen at all. Anymore insight? Thank you for the response tho!

the same problem...

by eleseff In reply to Buuut....

Hello ride_for_life13 and other readers,

my omnibook XE3 also beeps 3-3-1, I have the same error. I has complete demounted the notebook and i found the CMOS-rechargeable-battery. The Voltage measuring is 3.11 Volts directly on the battery.

In the service manual i did not found a solution for this problem.

You can help me, what is your solution for this problem?

Best regards

Replace the CMOS Battery

by styluspilot In reply to the same problem...


I too used to have this problem.

I have since replaced the Battery which is on the underside of the motherboard, a real ***** to get at, as you have to pull everything out.

I followed the Instructions in the service manual.

the Laptop works again after I replaced the Battery.
