• Laptop lags while charging
    2 replies, posted
I have an HP Pavilion dv7 laptop, and have had it for around four months or so now. Ever since I've gotten it, games would lag and stutter while the laptop was plugged in and charging, and the machine would even run hotter when plugged in, so I've gotten used to unplugging it and playing games until the battery gets low. More recently, videos would stutter and the machine just generally runs much slower when plugged in and charging than it does when running off the battery. For what it's worth, I still have all the original software this thing came with, as I was unsure what to remove and what shouldn't be removed (it didn't come with any discs, so I didn't want to be stuck needing a piece of software without a way to reinstall it). By friends recommendation, I've tried changing the power settings. High performance mode tends to make the laptop run 10 degrees hotter without fixing the problem, power saver mode causes it to run very slow making everything lag like hell, and I've been using the HP Recommended as it's the only option left. So, does anyone have any ideas as to how I can figure out what's causing this problem?
All I can think of is it's overheating while charging and it's causing it to throttle the GPU or CPU, have you dusted it? Assuming it's the model with the ATI graphics, try going into the CCC and fiddling with the power tab, it might not be set up correctly. What are the temps Plugged in & gaming, idle, and unplugged & gaming? If all else fails pulling the battery out while having it plugged in should work if it's the battery charging somehow causing the lag.
I haven't dusted it yet. Someone mentioned doing that in another thread, but opening it up to dust it would void the warranty, right? Also, incoming dumb question, but under the power tab in CCC, it mentions that when Plugged in performance is maximized while battery life is when running off the battery. Think that could be the culprit? I don't have screens now (will work on it though), but temps while idle are the same irregardless of power source, it's only when gaming that it runs hotter when plugged in. How much hotter depends on the game, which is now making me think it could be the power options for CCC. [editline]28th March 2011[/editline] The temps at their highest have been mid 90's for each core, graphics card, and mobo, so that shouldn't be whats causing the problem, right? Changing the power options in CCC didn't work, and neither did removing the battery and only being plugged in. Does anyone have any other ideas?
