How can I fix error 00163/00173 when starting my IBM Thinkpad 600E? When I try and go pass it, it takes me to a screen with on/off icons, which just flash.

First try dumping the cmos. Unplug the AC power, remove the battery, open the memory compartment. To the left you will see two wires, a red and a black, running to a little plastic connector ( the other end connects to the cmos battery) just unplug the little connecter, let it sit that way for 1/2 hour or more, reconnect the cmos battery plug in, put back battery and/or AC plug, and try retarting. If nothing, then replace the cmos battery.

Probably a flat CMOS battery. If you go to www.lenovo.com (Lenovo own all of IBM's PC assets now) you can download a maintenance manual. Step through the diagnostics in the manual and it will show you how to replace the battery.
