Both fan not working

Hi all

my old macbook pro has this problem. Both fan are at 0 rpm. I checked both and are not malfunctions... seems to be a problem with the SMC.

Important note: actually the MBP is working WITHOUT battery.

Question: use the laptop without the battery may affect the normal operation of the SMC and then keep the fans switched off?

Should I order a battery replacement for fix this?

Thank you

Fan not working anyway not even after resetting SMC...

I remember that the fans have always worked until I broke down the battery. Since I removed it, the fans have stopped working. I've ordered a new battery... I'll try to reset SMC after installed and charged it...

First I would do a SMC reset. Follow this Apple T/N: Resetting the System Management Controller (SMC) on your Mac.

SMC has a few different functions. So while it manages battery charging and battery power management. This part of SMC does not involve the temperature management side of things.

I do strongly recommend putting the battery back in (replacing it) only because when you don't have it present it doesn't take much to pull out or cause a power disconnect from the power adapter. The way the system was designed the battery would fill in the power disruption. Think of it this way your laptop has a built in UPS!
