Question about IBM ThinkPad T23 2647 Notebook

Fan turns on and off rapidly

I recently replaced the mainboard because when I turn on the power the light would come on but no response from anything. Now the screen lights up, the drives start up and the fan turns on and off repeatedly. I went through and checked all connections again. I am out of ideas. Can you please help!!!

The fan cycling problem on the T23 series usually indicates a loose solder or missing inductor which is usually on the underside beneath the PCMCIA slot. If you replaced the mobo yourself you may have flexed what is a weak solder joint loose - you will need to pull the board and resolder this or have someone else do this for you. You can sometimes get the laptop to start by flexing the assembled laptop gently around the PCMCIA slot and if so then that almost always means an inductor problem. You can find some photos by googling (images) "T23 mobo" or "T23 motherboard".

Easy solution is there :
Check the fan with external power (12v. DC). If damaged replace it. Give a clean windows installation when the fan is OK.
If your mainboard does not supply power to the fan than you have a major problem with mainboard. Replace mainboard.

Fan and remote not working


If you haven't already done so, replace the remote's battery with a brand new one . Make sure the replacement battery is NEW AND UNUSED, AND WAS PURCHASED RECENTLY, SO IT IS FRESH. Make sure it is installed properly, making good electrical contact, and the proper polarity is observed. Was the remote dropped, sat on or stepped on? Was a liquid spilled on it? Did your pet chew on it? Are any of the buttons loose or stuck? If the remote seems ok, try removing 120 volt power from the fan by turning off the circuit breaker or fuse an your homes main electrical service box. Wait 30 seconds, then turn 120 volt power for the fan back on. This may reset the speed control in the fan unit. If it does not cure the problem, consult a professional electrician, or replace the fan, whichever is more cost-effective.










wait 30 seconds and turn 120

Fuji F460 no power


Mainboard component failure at a guess or the new battery is not up to scratch- try taking the battery back for a new one as it is a recent purchase. If you can do that and still in trouble contact Fiji for a reapair estimate.
