Thinkpads Forum

Hi to all Thinkpad enthusiasts please help me if anyone can Thank you :-

1. I have Thinkpad 600 . whenever I boot the system I get error 192 and system does not boot not it goes to EASY SETUP (by pressing F1 before switching on).

2. I have put new CMOS battery and I do not get any other error except 192.

3. My CPU fan works sometime but then also I get 192 error.

4 Please help me ..

192(Fan error.)

1. Measure the voltage of the backup battery. If the voltage is not correct, replace the backup battery.
2. Fan
3. System board

See Lenovo Support Numeric Error Codes Index

How do I confirm if it is fan or system broad ??

The fan should spin up when the system is first turned on. It should run for about 10 seconds and then stop. If it makes loud grinding or rattling noises, then I would replace the fan. If it does not spin then the problem could be the fan itself or the motherboard. In that case, replacing the fan is about the only thing you can do to figure out the problem. The 600 has a built-in system diagnostics in the BIOS (Easy-Setup). If you can manage to boot the system into the BIOS, then try running those tests. There will be error codes for any problems that are found and you can check what they mean with the Hardware Maintenance Manual:

Hi all these are symptoms in my Thinkspad 600 2645 48U can anyone please help :

1. Error on booting 192 but cannot go in "EASY SETUP".
2. I remove CMOS battery , I get error 161,163 and 192.
3. I set time and reboot.
4. I get error 192,127.
5. I can access "EASY SETUP" and I do a testing of hardware , and get DEV -001 , Err-42 , FRU - 1110.
6. Also on checking advanced diagnostic mode I get "Fan not connected message appears"

So I am confused if it a system board or CPU card fault. Can anyone guide me ??

The diagnostic codes and error messages are pointing to the fan, the systemboard (the "11" in the FRU 1110 code) or the CPU card (the "10" in the 1110 code). I would still verify these two things before spending any money on a solution:

- measure the voltage of the "new" CMOS battery. It should be around 3.10V (or slightly more). If it's less than 2.80V then it's not new and probably should not be trusted. Report your findings.
- does the fan spin up when the system is first turned on AND do you still get the 192 error code? If the fan does NOT spin, you could have a defective fan or a problem with the motherboard. Again, really the only way to tell is to replace the existing fan with one which is known to work.

I doubt that there's a problem with the CPU card. Most of the 192 errors happen from a low CMOS battery or a bad fan. It IS possible that there is a problem with the power going to the fan or the monitor circuit on the motherboard which is supposed to keep track of the fan's operation, but those things are much harder (if not impossible) to fix without having to replace the entire motherboard.

edit: Just noticed your other thread about the differences between the CR2025 and CR2032 batteries. Am I to assume that you are using a non-standard CMOS battery, that is to say, one which does NOT have welded on contacts to the battery? If you have "made your own" CMOS backup battery, then you better double-check that the polarity is correct. The red wire should go on the "+" side and the black wire on the "-" side.

Thank you for the prompt and detailed reply , some clarifications are :

1. After using the battery I do not get 161 163 errors.
2. The fan does not always start on itself I have to blow and then fan starts working, after that I reboot fan works but checking in checking advanced diagnostic mode I get "Fan not connected message appears"

If blowing on the fan makes it start up, then I would replace it. That might be the cause of the 192 problem. If the laptop does not detect the fan spinning when it should, you will get the 192 error. It sounds like the voltage or signal is being delivered to the fan but it may be stuck due to old age.

could there be error in board not detecting it once it has started after blowing

Ok I have put a new CMOS CR 2025 battery and when I switch on I get 192 and laptop stalls. I cannot go to the "EASY SETUP" even if I keep holding F1 key.How can be sure if it is CPU or FAN problem. Also can I use "FRU 08K5909 instead of FRU 05K4830 in Thinkpad 600 2645 48U

About the only way to determine what the problem is when given two choices and you do not have access to an identical computer, is to replace the cheaper or easier one and hope that fixes it. If that doesn't work, then replace the second component. In your case, being where you are, you may not have access to either an extra fan or CPU module or it may cost much more than the system is really worth. If you do have another 600 system, then transfer either the fan or the CPU to that system and see if the problem follows.

Yes, there could be something wrong the motherboard. But since you say that the fan does not spin by itself some times and that you have to blow on it to get it to start, then I would start with replacing the fan.

The 05K4830 FRU is what is listed in the 600/600E Hardware Maintenance Manual. The 08K5909 fan is for the 600X systems and I would not try to use that one.

edit: To clarify my last sentence, I do not know if those two fans can be interchanged. I'm assuming that they cannot, simply because they have two different FRU numbers. I know that in some cases, two completely different FRUs can be swapped, but here, I do not have any personal experience to say that it is possible. Therefore, I take the "safest" stand and say stick with what the HMM says you need. You could also try searching the archives at this site or do a general web search to see if somebody says that it is or is not possible to exchange those fan assemblies.
