1. Power on the system.

2. When the message Press F1 for IBM BIOS setup Utility appears at the bottom right hand corner, press the F1 key. Wait for the BIOS Utility screen to appears.

3. Select System Information. The BIOS version is displayed at System BIOS Version line.

When everything else fails, read the instructions.

Hardware Maintenance Manual Aug 1998

Disabling Power-On password - page 8 of PDF

Disabling the Power-On password and Supervisor password - page 9 of PDF - you must know the Supervisor password.

Reset switch - page 9 of PDF

- error codes - page 26 of PDF

163 - time and date were not set.
You have to go into the bios and set the time and date after you have removed the battery then have replaced it, Save bios settings.

NOTE that if you can't get into the bios Setup, setting the time and date in your operating system on the computer will usually, if not always, set the the bios to the same time and date values as in the operating system.

161 - dead battery (or it's connected backwards)
1. Go to "Backup Battery Checkout"

Page 17, 18 of PDF - Backup Battery Checkout
If the battery voltage is okay, and if it's plugged in such that it's polarity is correct, then if you still get the 161 error, you probably need to replace the system board (motherboard).

Page 47 of PDF - remove / replace backup battery
If the plug on the battery's wiring can be plugged in either way, make sure it's plugged in the right way - there may be a + beside one side of the connector it plugs into.
If that's plugged in backwards, or if it can't be plugged in backwards but the plug is wired backwards, the bios will behave as if the battery is dead or it's not there.

Did you get the correct non-rechargable battery ?
This laptop cannot charge a rechargable backup battery, and if you got a non-rechargable one that is not compatible with that part number / this laptop, it may be wired backwards to what you need it to be at the plug.

In earlier IBM computers a reference disk (floppy) was used to reset the CMOS settings.

Thanks for the reply..
I am sure the battey is the right way around (the connector does not allow wrong connection) The errors 161 and 163 come up and no prompts come up to press F1 to enter the Bios.

I get rectangular screen confirming errors again and prompting me to accept or cancel the error notification ..I can use the mouse pointer to click either but in each case i get a message again giving the errors and to look at the instruction manual. I can't get past this point.

I can only think that either the pins on the motherboard that I plug the battery into are dirty or loose on the motherboard. The battery voltage is good(the old one zero)

Any other suggestions before i try to clean the connector on the motherboard?

The Bios must be entered to clear the error.
How old is this computer?

Take a look at the old battery and compare it to the replacement. Is the polarity of the wires at the plug on the wires the same ? Is there a + beside one side of the mboard connector ?
If the old battery leaked, there may be corrosion deposits in the connector on the mboard. If there is, a bit of household vinegar should clean it off, but you'll have a hard time getting in there with anything to scrape or wipe off anything.

I didn't look at the User manuals. They should tell you how to get into the bios. If you can't do that,
- your built in keyboard is OLD if it's the original one - try a different external keyboard.
- as I said above...
"NOTE that if you can't get into the bios Setup, setting the time and date in your operating system on the computer will usually, if not always, set the the bios to the same time and date values as in the operating system."
but you would need to fix whatever is causing the 161 error.
