    In the device manager, disable the ACPI Battery. This was the cause of my Latency issue with every laptop I've owned since using Windows XP. I thought this may be the cause for my G73jh also.

    And it is. It may be for you, not sure, but good luck. You may want to turn it on while on battery. The other solution is to just take the battery out while you are on A/C.

    Now mine is in the mid 100s, around 150. But then some have very low standards for latency like this one Dell user thinks this is ok. I would go crazy if I had this :p

    It seems latency is on the back burner for a lot of laptop manufacturers. Asus and Dell and Acer for me all have had latency issues. And the only fix so far has been to disable the ACPI battery.

    What kind of Latency, it's likely obvious; that's why I don't get it. :'(

    All I know it reduces my latency from mid 200s-300 down to mid 100s.

    Does you not loose power plan options if you do that??

    You can change the power plan options through the control panel.

    But if you don't want to disable the ACPI Battery, just removing the battery will have the same effect.

    Hello Ruckus,

    Out of curiosity - Do you have the Intel or Atheros WiFi Wireless Adapter? My G73JH BestBuy version came with the Atheros and latency was a huge issue. Latency Measured continiously well above the 1000 range with regular spikes above 5000.

    It would be interesting to know if there is something happening in the relationship between the Atheros and the ACPI Battery control.

    I switched out my Atheros for an Intel 6200 and my latency with ACPI Battery enabled is within the 150-250 range with only a single spike, in the last 15 Minutes, above the 500 range.

    In Peace and Agape,
    Trav...

    I have Atheros with drivers from Laptopvideo2Go and I don't have any latency issues. Even with ACPI battery on I was around mid 200s to 500. Taking the battery away reduced it to mid 100s to 300.

    This is just another way to lower your latency for those who do audio work or even visual where latency matters. This isn't to say that the G73jh has high latency etc. But some like latency to be as low as possible. And pretty much with any laptop, I've noticed the ACPI Battery to raise latency. Good luck.

    If you have a USB device plugged in (especially an audio related device such as Serato or an audio interface) a PC with high DPC is unusable due to audio drop outs
