I guess you could say it's idling.ĭoes anyone have a clue on what's going on with my laptop? I'm completely lost in this, seeing that adjusting the values in ThrottleStop's power limit window had no effect.Īctually, I seem to have a very similiar issue, in my case it is a Lenovo Y50-70 notebook.
Under next to no load applied, this is how the Limit Reasons window looks like. At least that's what I could tell from the values in there, I might be wrong though. Again, unfortunately it appears that my laptop doesn't seem to use the MMIO method to control the power limits. Then I tried another way to get around this annoying problem, MMIO addresses FED159A0 and FED159A4, which stored the long and short term power limits. The 'GPU POWER' box still popped up with PowerCut enabled. In another run, I've tried using PowerCut to trick the Core i3-4000M into thinking that it used far less power to prevent the power limits from setting in. My previous power limited run was done with this configuration set (Turbo Power Limits, FIVR Control). The power limit seems to only kick in under GPU-intensive tasks, and not under CPU-intensive tasks. This is how it looks under the influence of power limit throttling. According to ThrottleStop 8.70.6, it indicates a red 'GPU POWER' box to display that it's throttling hard. I believe this issue has something to do with the HD 4600's power limits, but I'm not exactly sure if that's the actual problem.
