iMac 21.5" Mid 2011 2.5 GHz Intel Core i5
Hello,
I'm having trouble with my 21.5" iMac. After working for 2 - 3 hours the mouse with Bluetooth and USB port connected keyboard stop working.
Sometimes I can work a whole day without any problems, other times it stops and I have to restart my system to get it working again.
How can fix this? Thanks
I have this error: 4SNS/1/40000000: TH00-9.000

Someone put in a replacement HD and forgot to add in the needed hardware sensor if they put in a non-Apple drive the system came with. Here is the needed sensor: OWC In-line Digital Thermal Sensor for iMac 2011 Hard Drive Upgrade and here is the needed steps to get to it: iMac Intel 21.5" EMC 2428 Hard Drive Replacement. You can stop as Step12 to slide on the sensor for the drive you have now.
这个答案有帮助吗？

Have you tried running any diagnostics? How about rebooting your system and holding the 'Option' & 'D' keys to let the builtin diagnostics run
