Latitude E6510 Owner's Lounge

My system would hard freeze as well. I suspected it was a driver issue related to power management. Change your power plan to either High Performance or Balanced and see if that stops the freezing - it did for me.

I set my system up for a bugcheck to debug the hang, but it stopped hanging :-(

Mine is at high performance and it still freezes. I only installed itunes, WoW, windows live, MS office 2007, google chrome, adobe reader, adobe flash player, and this thing would freeze 2~3 times a day. Driving me crazy...

How did you do a bugcheck?

 

I'm running Debian Testing (Squeeze) on this machine.

fyi: this is no longer neccessary from kernel 2.6.34-git16 onwards.

I haven't noticed this problem yet (though I haven't tested extensively yet).

This touchpad uses a new protocol that is not supported yet - see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/550625 for more details. Some have reported to have working scrolling, but it does not work for me.

 

Could everyone please test something? I received my Latitude last week and noticed that when certain apps are running a high pitch noise is emitted from my laptop. It's easy to reproduce with Google Chrome and sometimes with iTunes. Close all other applications, listen carefully if there's a high pitch noise and then start Google Chrome (or iTunes) and please tell me if you can suddenly hear a high pitch noise noise. Then close Chrome and test again if the noise is gone. I'd like to find out if this is a general problem or just something that happens in a few laptops (such that replacing the laptop could solve the issue).

Please don't forget to mention which CPU you're using (maybe it's only a Core i5-520M problem). Thanks a lot!

BTW, the noise seems to be coming from the bottom side of the laptop, somewhere near the top right of the battery.

 

Does hibernate work for you with Windows 7 64-bit? Maybe it's because I installed in UEFI mode, but the system just reports that it can't load the hibernate data.

 

I have the problem as well. It's related to the way the BIOS is using some virtual addresses during boot...

 

This is a known issue with many Intel chipsets over the past few years. When the CPU goes into low power modes, components on the system board emit high-pitched noises. There are some fixes out there, but none of them is foolproof. You'll have to search around more for info on it.

 

Yes, it's often called "CPU whine" though it's not actually the CPU that whines. I just hoped that it might not be present in the majority of the E6510s. Before this laptop I already tried a Toshiba Tecra A11 which had a constant very high pitch noise and an ASUS which had no noise, but the display was unacceptable. Now this is my third attempt at finding an acceptable laptop for work in my very silent office and if almost every E6510 has that noise I'm going to wait for the next CPU generation until this stupid problem is finally fixed. I can't believe that it's so difficult to make a silent business laptop. Some resin for the problematic components should fix all problems very cheaply...

 

OOORRR You can go with AMD CPU's and the problem is entirely solved.
AMD CPU's got quiet better over the years, they heat much less, and you can find models of equivalent performance than Intel's CPU's (well maybe not the new Intel Core i mobile series, but it will come, or perhaps the high-end AMD CPU could be equivalent than a lower end Core i, which might fit your needs...

To be honest for me, I dont' buy a laptop for the CPU, unless there is something specifically wrong about them, for instance the early AMD Turions used to be big heaters, and provide lower battery life. Now it has changed.

As long as you buy Intel CPU's, Intel will NEVER fix the problem. Why spend millions out of your billion dollar profit, to try to fix a problem that no one complains (read: reduce sells) about. That last statement is what Intel executives are probably saying.

 

Well, I'm not really a fan of AMD notebook CPUs and with an SSD CPU performance might play a more important role, again.

Also, why is that Intel's fault? Isn't it the notebook manufacturers' fault because they don't use higher quality silent components? After all, the noise isn't caused by the CPU itself, but (AFAIK) by some component that takes care of the voltage switching for the CPU's power saving modes. The notebook manufacturer is responsible for that component, not Intel. In that case, buying an AMD won't change anything.

Anyway, does every E6510 actually have that high pitch noise when you start e.g. Chrome? Maybe only 10% of those laptops have that problem. At least, I've heard that the CPU whine problem appears far less often on the Core i CPUs.
