Agilent 58455A battery
« on: November 25, 2017, 09:05:31 am »
Hi,

I'm servicing my oscilloscope and found that the Motherboard CMOS battery is lost. The service manual has a simple drawing of the pc-side motherboard which says its 3V, but not the exact type. Can somebody point to a correct replacement buttoncell ? I tried a cr2032 I had on hand, but the scope didn't want to boot with it.

Best regards

The battery replacement causes CMOS RAM data to be lost. You need to configure the BIOS. See page 5-16 of service manual.
Keep us posted if you could fix it.

The CR2032 battery worked after all. I needed to do a reset of the bios with the jumper, then it booted  :palm:
