I recently purchased a custom built HP Spectre directly from HP. I unboxed it yesterday, June 24th. I soon discovered an issue with the inputs lagging.
It only occurs when on battery power. The mouse and keyboard will freeze and be unresponsive for anywhere between 2-30 seconds. I've had the Task Manager open while the issue is occurring and it revealed nothing out of the ordinary. I have tried updating drivers for everything in the Device Manager, resetting Windows on the pc and uninstalling/reinstalling the drivers for the battery. None of them have remedied the issue. If I plug in the charging cord and the machine is charging, then there is no problem. I'm suspecting a hardware issue, but I cannot say for sure.
