Ibm thinkpad 9547 wl4 will not boot

It's dead Jim. Thinkpads have no parts availabilty, you will need to get a new one.

The 161 error means the BIOS battery is dead (flat).
The 163 error means the Date and Time is not updating.
The BIOS battery needs replacing and the BIOS settings need to be configured (ie the date & time)

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.

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!!

161 and 163 error means you have to change your CMOS battery. open the laptop, change the cmos battery and you should be able to set the date and time.

after which you can access the bios by pressing F1 upon boot up and change the boot sequence after that

Try this:

Press and hold F1; then power on the computer. Hold
F1 until the “Easy-Setup” menu appears.
If you have set a password, the “Easy-Setup” menu appears
after you enter the password.

yes hit fn key again ok on kb itself that togles between #s and letters ok thx nick

Format the harddrive and install an Operating System of your choice.
Good Luck.

PS: You can probably disable that memory check in your BIOS to speed up your boot time as it is not necessary.

try pressing Fn F7
