    Laptop CPU Speed Throttling & Battery Charging

    Hi All, I have a Lenovo ThinkPad E540 with an I7 4702MQ (it came with an i5). I have a problem whereby the laptop sometimes doesn't charge the battery and when it does (after I unplug the power lead and plug it back in again), the CPU is throttled to 0.79Ghz. I would add that the same problem...
