Thinkpad T510 Owners lounge

I think that's VGA port.

It is a pity that this small part does not fit with the chassis tightly. Otherwise it is perfect! Hope it will finally get fit with the chassis after some use.

 

Hmm... Would you suggest some brand else?

 

Right now it is happening in AC mode too.

I'll mess around with the BIOS for a bit after I finish with my homework. I really hope someone can find a solution to this somewhere. My C90S and EEE never made any noise like this.

 

BIOS (v1.12) - Config - Power
Speedstep - Maximum Performance both AC and Battery
Thermal mgmt - Maximum both AC and Battery
CPU power mgmt - Automatic
PCI Bus power mgmt - Automatic
PCI express power mgmt - Automatic
Most unused devices turned off (about half of them) in Security
* some BIOS settings appear to be overridden by Power Manager, so I leave them in high settings

Power Manager (3.12) Maximum Performance (I restored defaults)
Changes: Intel graphics - Maximum performance both AC and Battery, and lowered brightness
* modifying the first few "System settings" appear to affect Turbo, such as setting "optimize Fan control" to "balanced" disabled Turbo in most/all my tests.

Turbo appeared to have the most affect on voltage (changes), which make sense, my i520 regular clocks at 2.93, and makes a big difference in performance. But I suspect any significant voltage change will cause the noise. If this is true, then fixing this for good may be difficult given the dynamic nature of the T510, i.e. i520 Turbo, graphics power mgmt, Wifi power mgmt, etc, etc.

As mentioned, I really only have motherboard noise during Windows startup, and loading big apps like Lenovo tools. Seems the noise is directly below the "A" key.

 

HI, i am wrong again, after the changing the hard disk, the noise continues, the its actually a CPU whine or some other name. Anyway, my problem is lasting whether the AC mode or the battery mode, it's really annoying.

I have searched the forum and have not found a suitable solution to the new i5 i7 processor...

sigh...

 

Can someone record this "CPU whine" on the mic and upload it somewhere? I want to listen it before buy.

 

I can confirm this is working. I haven't been getting the noise on battery today and didn't get it last night on AC. I'm getting a little less battery life (about an hour less, still getting 5-6 hours solid though), but it is worth it. I'll no longer get a headache when using my T510!

Thanks a TON, maybe even two tons for this help!!!

 

No hard feelings, I took the wrong smiley. I just wanted to clearify that's not a real issue or failure...

 

I'm still getting it when using FF with some flash loaded.. or Chrome opened (w/o any page loaded)

Is your noise all gone? or just only when it's idle?

thanks.

 

I've not heard it under any situation since I made those changes- including HD youtube videos, Visual Studio, Dreamweaver, Photoshop, and MS Word. If it was going to make the noise, I'm pretty sure it would have by now.
