The off switch doesn’t turn the camera off. However switching it to on turnes it on after it falls asleep.

Hi, Check the Auto Power Off setting in the Power Management settings of your camera. The default setting is 2 minutes. I think that when you change this setting to OFF that you have to use the off switch to turn it off, otherwise it turns itself off dependant on the setting selected, irrespective of the off switch. Here is a link to the User Guide, On the right side of the page click on The Setup Menu, then scroll down to Power Management for a description of Auto Power Off. http://fujifilm-dsc.com/en/manual/x100t/

hi, check the setting of camera and select auto on off switch

Old post I know, but I was able to fix this same issue by blowing real hard into and around the on/off switch. Silly, I was exploring taking the whole thing apart.

I have this issue in my X100 for years now. At first it’s just an intermittent problem, camera randomly comes to life despite being switched off and drains the battery. It gets worse over time. Here’s my way to cope with it: Leave the switch in the ON position AT ALL TIMES. Don’t fiddle with it.Set AUTO POWER OFF – 2 minutes.OVF POWER SAVE MODE – ONThis turns off the sensor when used with the optical viewfinder, except when you half press to measure.QUICK START MODE – ON (comes to life in 0.7 instead 2.7 after half pressing the shutter when the camera is sleeping).Be sure to to switch to OVF every time you stop shooting to benefit from OVF Power Save mode.If you are not using the camera for prolonged time, or pack Your gear for transport, remove the battery.

That’s it. No problem.
