Re: t40 2373 ibm fan error
One of three things; 1- when the fan codes on some IBM's, the code locks in the bios, there is a download the has to be ran in order to clear the code and the machine to run properly. Check IBM's support site to see if this is the case for your machine 2- If the machine overheated in the process of the fan going out, then the processor may have been damaged, causing the problem and 3- if there was a malfunction with the motherboard which initially caused the fan to stop working, a new fan won't work either. Test the old fan by hooking power up to it, it is power direct and has two leads positive and negative, when power is applied it will run or not. If it does run then the problem is with the motherboard. Try these and get back to me.

Fan error usually means the fan isn't working and may cause the system to overheat and destroy the intell chip. Probably need a new fan and it will be expensive to get done and hard to find someone to do it. Ask IBM for help.
make sure the fan is pluged in correctly and you didnt unplug anything else such as memory or etc or bump the cpu... did you put any thermal paste on the cpu when you put the fan on it? its needed to bond the too together to make a better cooling system there maybe a setting in your bios to disable fan monitoring or cpu temp etc have to look at your bios to see
your cooling fan is reporting as damaged you need to replace the fan unit (cooling pad as well) likely service is required and unless you want to disassemble your laptop a service center would be better suited for this job.
Are you talking about the original fan being good or the replacement? If it's the original, then your problem may lie with the processor or mainboard. Try the download first, you will need to access another computer to make a bootable disc for the download to clear it. I believe with IBM you can make a bootable floppy or CD. If you have a floppy for your machine, some don't. Once you've made the disc or floppy, you will need to enter the boot menu, and boot from the proper drive. I'm out for the night, but I'll be back in the morning. Let me know.
The battery that might be dead is not the main battery. It's the cmos battery, which is a coin cell battery located on the motherborad. It stores the setting in the bios and keeps the date and time accurate. Errors 161 and 163 mean the date and time are wrong. If the cmos battery is dead then, the date and time go back to 1/1/2000 every time the pc is restarted. Thus, you get the "wrong date and time" errors 161 and 163.
Before getting the fan replaced you may want to try to blow the fan with an air compressed duster. Worked for me. You do not need to take the laptop apart completely. There are 4 screws that holds the keyboard in place, unscrew the 4 and you should be able to pop the keyboard out. Once the keyboard is off you should be able to clean the fan.
