Microsoft today acknowledged the Surface Pro 3 heating issues and promised that they will be releasing an update to fix this issue soon. They also revealed that this affects very small number of Surface Pro 3 Intel Core i7 devices which are temporarily restarting and incorrectly showing a “Thermometer Gauge” icon while attempting to boot up
“The Surface Team is aware of a very small number of Surface Pro 3 Intel® Core™ i7 devices that are temporarily restarting and incorrectly showing a “Thermometer Gauge” icon while attempting to boot up. Our investigation reveals that the system is triggering this event sooner than it should for some people, only when the device restarts, and this does not occur when the device is booted and running. We have an update that will address this that will be ready for our customers as soon as possible.
The i7 version of Surface Pro 3 is a first-of-its-kind tablet delivering i7 processing power in a thin and light package. As such, the increased power calls for the fan to spin more regularly and at higher speeds – and for the unit to run slightly warmer. If customers have any questions or concerns, they should contact Microsoft Support.”
