I agree fully that ASUS cheaped out on the power supply for the G74: the following is my estimate of the minimum wattage that the G74 needs at "full throttle":Ĭhimei Innolux 17.3 LED (N173HGE-L11/L21) = 9.3W I believe this is the more likely explanation, since CPU Throttling can be worked around with ThrottleStop using the stock power adapter. Also config it to Start Minimized if you are going to have it start at Windows boot. What you want to do is disable it, and it only needs to be configured once every boot-up, until a BIOS update exists. The culprit is the Bidirectional PROCHOT function, which handles this throttle feature. It's called ThrottleStop, and version 3 was updated to support Sandybridge systems. This will require a BIOS fix, but until then, there is a great workaround provided by Unclewebb. Unfortunately I feel that the protection is triggered too easily, and many people will have a performance loss while playing their favorite games. When the system is under load, especially when the GPU and CPU max out, like say, when you are gaming, the BIOS/Chipset has a safety feature that will throttle down the system to prevent damage. Whether the Battery Saver setting disabled the battery from charging I can't say for sure.Sandybridge Throttle Issue and Workaround This totally drained the battery, and because the setting was enabled to use Battery Saving when power dips below 20%, every morning the laptop would be SUPER slow. So I guess that every day when the client went home, he closed the lid and put it in his laptop bag. Note: I noticed that all the battery settings for "Pressing the Power Button", "Pressing the Sleep button" and "Closing the lid" were set to SLEEP. The battery icon at the right bottom of the screen should now change to "Charging".Īfter this the CPU started running at 100%, 2.48Ghz and the machine worked well again.įor good measure, click on the battery icon again and set the power mode to "Best Performance" Unplug the charging cable and re-plug it into the charging port of the laptop.Disable the setting: "Battery saver status until next recharge".Untick the option for: "Turn battery saver on automatically if my battery falls below.". ![]() Double-click the battery icon ( not right-click) at the right-bottom of the screen (in the tray).To resolve it, I did the following (perhaps this could work for you too): I noticed at the right bottom of the screen that although the laptop was plugged into power, the battery icon said "not charging" and battery level was 1%. The CPU ran at 30% maximum utilization, at 0.48Ghz PERMANENTLY, every day. The machine took almost 30 minutes to open Outlook and was terribly slow in general. I had exactly the same problem at a client today with a Windows 10, Dell Celeron Laptop. HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\intelppmĪfter that the CPU was no longer being clocked down to a low speed, and the Maximnum Frequnency under Resource Manager now shows as 100%. At the left pane, navigate to the following registry key:.In run command box, type regedit press Enter to open the Registry Editor.Simultaneously press the Windows image R keys to open the 'Run' command box. ![]() This may especially be the case when slowness occurs on Laptops which are currently plugged in. I finally found that I needed to prevent the "intelppm" service from starting (and subsequently malfunctioning), using the registry. I tried adjusting everything within Windows Battery and Performance settings that I found here and on other forums, but to no avail. This defines the maximum speed percentage which Windows will allow the CPU to run at. (This should instead be showing at about 100%). ![]() From here I found that Maximum Frequency was capped at 30%. If I went under Task Manager > Performance, I found that CPU usage would not go over 30%, and the Speed was clocked down to 0.78GHz.Īt the bottom of the Performance tab there is a button to Open Resource Monitor.
