Error 163 is date not set.

When you get a set of errors like 163, 192 and 161 (invalid date and time and invalid cmos settings) , and the thinkpad not starting, that means that the cmos battery is completely drained and must be replaced.

The Cmos battery is located on the lower side of the motherboard, and can be accessed from the memory compartment.

You can order the battery at a local reseller, or buy it on Ebay for a small fee.

See the guides below on how to replace the CMOS battery.

Hi there.
Errors 161, 192, 163.
All three of these errors are connected to the back up battery.
To resolve this problem:
1. open memory flap on base of laptop (small philips screwdriver required)
2. find the small connector with 1 black & 1 red wire coming from it.
3. disconnect above connector and gently pull the Red&black wires. The backup battery should just pull out from under the casing.
4. get replacement battery. Either
a. call IBM spares (07900 247 490 in UK) and ask for FRU:
02K6502. UK price is about £8 + £15 delivery + VAT.
b. if comfortable with soldering iron: Carefully open the packaging on the backup battery using a sharp knife.
Remove the solder tags from the battery (these are spot welded so need to be cut/broken off). Buy a new CR2025 battery from any computer shop, jeweler, or camera shop.
Using electrical tape, insulate all round edge of battery
Solder the leads onto the new battery - note polarity. Red wire to +, black wire to -.
Using more insulating tape, wrap battery so that all exposed metal is covered.
5. put new battery into laptop (reverse steps 1-3)
6. start up computer, error 192 has gone, but still shows 161, 163. Select OK.
7. reset date & time, and OK
8. when screen shows 'O / I' restart laptop using on/off switch at side.

Good luck and thanks for using FixYa!!

Error 161 and 163


The ThinkPad 600E is at least 5 years old? If so, have you changed a RTC Battery (CMOS Back-up Battery) 3V Button cell type that goes somewhere inside the Laptop and sits on the System/Motherboard. I hope you put it back the right way polarity is critical. If not then i have no idea to what it is, though someone will be able to help also you might want to try http://www.computing.net/answers/hardware/ibm-thinkpad-bios-error-code/ good luck, Bastian

Errors 161 and 163 mean the time and date are not set in the CMOS. This typically means the CMOS backup battery is dead / going dead.

IBM Thinkpad error code 19990301 is a Hard-Disk sector problem. Basically your hard-drive is faulty and you need to replace it. This is why it wont boot; because the area of the hard-drive that stores data is damaged.
