I am trying to restore my IBM 600E Thinkpad. I

I think it is a thinkpad error message related to CMOS battery, Try to enter the configuration utility and set the properly date and time. If this solve the problem you should replace the cmos battery.

These errors are system options not set, and time/date not set (if I recall correctly off the top of my head)
Basically, you need to replace the CMOS battery.
I would order one online from a place like EVERCORP.com ( a link for YOUR battery is here... http://www.evercorp.com/catalog/batteries/Laptop/Laptop+CMOS/IBM/ThinkPad+600%2C+600D%2C+600E%2C+600X/CR2025-WR/ )
It will cost a lot of money though...almost $10 ! And there will be shipping on top of that, and the battery weighs almost a whole ounce!
If you can maybe second mortgage your house so that you can afford these hefty costs, the installation is almost as hard as the price is high.
Fear not though, installation instructions should come with the battery (which hides in the RAM compartment as I recall).
Once the battery is replaced, set the system options and the time/date, and you should never see that error again!

this error is the battery by the sound of things, you need to replace the cmos battery , then enter the configuation utlity and set date and time, hope this helps

Usually this means a hardware failure. I would suggest reseating the CMOS battery overnight to reset the system. Also you might want to replace it as well. It could also be more serious such as a motherboard component failure.
Also IBM error code # 189 according to Scott Mueller's Upgrading and Repairing PC's (8th edition) - "Excessive incorrect password attempts." Is there a password on your CMOS ?
Also try hitting ESC key on boot to bypass. Good luck!

i have an error 00161 and 00163 on my thinkoad how can i overide this issue

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!!

try replacing the cmos battery

I had exactly the same problem and once i replaced my cmos battery it cleared the problem.
you can find lots of good instructions on here to tell you how to replace the cmos battery

Error 19990301 on a Thinkpad 600 usually indicates that the hard drive is not properly connected, and error code 19990305 signifies "no bootable device". So, it's the hard drive.

First of all, I would try removing and replacing the drive to see if that cures it. You can get the service manual from Lenovo at http://www-307.ibm.com/pc/support/site.wss/document.do?lndocid=LWIK-3SYPX2

If this doesn't fix it, the hard drive is faulty. However, small size hard drives (10 or 20Gb) which suit these older machines are very cheap on eBay.
