T61 Fan Error - Evem after replacing fan [ Editado ]

[Fisticuffs]

Hey guys,

I have a two year old T61 14.1 Widescreen, Model 7662-CTO with discrete NVidia GPU

Last week I was using Thinkvantage system update as I had just done a fresh install of XP on new HD. It downloaded the files and installed them, however upon restart just booted to a blank screen. I could only access the BIOS and had not made any recovery points, so I decided to reinstall windows again using the Rescue and Recoery CDs.

I was halfway through loading the first recovery CD when it shut down. I restarted and got the fan error message. I tried TPFanControl/ PC Doctor etc to see if I can get it to spin but nothing.

I put in my old HD (functional) to boot to XP, and updated the BIOS using the utility, but to no effect.

I replaced the fan with a brand new unit off Ebay (42W2642) as per the manual and service training videos, applied AS5 etc. I turn on my comp again, and fan error again.

True, the replacement could be DOA. But I think it may be a BIOS / motherboard / fan controller problem. Has anybody encountered this problem or have any insight?

Thanks, I really miss my T61

The old fan motor might have shorted. If so, you may have blown a fuse (F4). Lenovo doesn't replace them, but some repair places might. It is surface mounted and used lead-free solder, so you need a rework station to do it. If you care, it is usually on the bottom and near the VGA port. It will usually have a "N" designation on it.. If you have warranty remaining, now is the time to use it. Lenovo will tell you you need a motherboard
