Updated BIOS, now weird harddisk noise, when I surf the net [ Edited ]

[Berthold2000]

I've just updated my BIOS, but now I hear a "buzz", when Firefox is loading a page or when I surf through websites. How can I fix that? I don't believe I needed the update anyway, though my ThinkVantage menu told me so.

Cheers, B.

Laptop model, hard drive model, and CPU? If this is the same thing I'm thinking of then it either appears when scrolling or disappears when scrolling.

run the hdd diagnostic from the bios menu, and report back.

i actually think it isn't the harddisk, but the ... em, screen or something. it's the scrolling noise, yap, but little when i scroll up and down, more when a new website is built up,

how do i get to the bios menu (i know, i suck)?

Hit F1 to enter BIOS when the ThinkPad POST screen shows up right after you hit the power button. However, I'm fairly certain it's a case of CPU whine.

Open Power Manager, hit Advanced, go to the bottom of the Global Power Settings tab, and post what the settings for CPU and PCI bus power management. I have the same P8700, and have no issues with it. Perhaps you can try using RMClock to undervolt (probably make the noise go away and improve battery life).
