Freeze

[Quantom843]

Every so often no matter what task I am performing on my laptop it will freeze for a few moments then everything will be sped up for a second, it usually happens when i am watching videos or playing video games. I am not sure if shifting around causes the freeze or if it is software/hardware related. i beleve i have a lenovo g470. thanks for any help provided

Hi Quantom843 and welcome to the Community,

If it does this while it's being held, or being moved, it's probably the Active Protection system.  It stops the hard drive if it detects movement. It thinks it's about to fall.

There should be an icon in the taskbar for the active protection. There's a slider that you can adjust sensitivity with. If there isn't  an icon there, there should be one in Control Panel.

I didnt know about this "Active Protection system" is there a such thing linux side ?

But Lenovo g470 has some fan/temp issues search in other threads you're not alone

Let me suggest to monitor temperatures i noticed that it start around 30 and then goes to 40-45 on idle and sometimes it skyrock to 70C tell us what are the higher temp you get ... I suspect games are stressing your computer more than just reading the manual ...

but I may be other reasons ... so we will have to investigate

1st let's try to describe a reproductible test ie :

boot

start temp monitor

play a movie

and report the min/current/max temps

i seen this alot on a G575.
it a flaw i think certin to flash.
happens in facebook and youtube.
as for the active protection just click uninstall.
most all notebooks dont have have it.
it a old ibm thing from the days when people would slam laptops around.
the do fail sure i just replace one for a kid and i tossed in a 64gb asax barefoot for her for a cnote.
any barefoot model will work great on and there easy on power and cheap now.
sandforce i stay away from.
toss in a ssd and it be carefree.
as for the freeze from flash well i think flash is buggy allways adobe is like the worst of the worst software companys.
if it flash 11 then it that for certin.
install the older one and turn off update and try that.
also tool bars do this alot more so then anything as the fight it out for control over flash ads.
as for temps well sandy bridge is a hot chip.
you can down clock it under windows power settings just set it less then 100%.
also you set it to passive that will slow the clock before the fan.
no snake oil needed really to slove sandy bridge loud fan issues.
slow it down to a culv speed and trust me sandy packs plenty of ponys under the hood even at 1.2-1.8.windows power settings has plenty of settings however i would under volt a sandy if i got a hold of one but i am advanced.the notebook forum review has a lot of info on lenovo.
