    You say that like it's a bad thing. :)

    I've noticed electrical noise from the speakers :/ It begins when I start a game and has variying pitch depending on what's on screen.
    Nothing to be done I suppose, atleast it's not as bad as in that video earlier (ingvarrs I think). It gets drowned by fan noise when they ramp up.

    Absolutely that's why I donated $20 when he released the bios and vbios. I also donate for things I use. However since I already donated in not sure I'm going to donate more as money is tight for a bit...

    why do people seem to get issues with the speakers on this machine?
    is it specific for this particular model,or for sager/clevo?or a bad batch?
    is there a way to fix it?

    I believe I get it also from time to time so I think it is just like stated above a result of electrical noise. If true then yes it can be fixed by further insulation of the culprit. This wouldn't be easy as finding the issue would be very difficult. If it is the same noise I hear then it only happens every now and then and then goes away after a few seconds. Which then confuses the fact that is it really electrical noise or not. Either way yes it does exist but unless you have one of the laptops which is was really bad it's not really an issue but rather we are a group who analyses ever aspect of the machine so little nuisances for most can seem like big problems. It's the nature of a tech forum.

    It's pretty much every computer in existence. The problem is wires connecting the amplifier to the speakers (when built in) or to front panel headphone jacks (for towers). These wires pass over, under, around, or otherwise in close proximity to other circuits in the chassis. They pick up RF noise from these other circuits exactly the same way that a radio antenna picks up RF broadcasts. Some designs are better than others, some are worse, but they all suck to one degree or other.

    It can't be fixed. Even if you were to shield the speaker wires they have to be exposed where they connect to the amplifier and the speakers. Noise will get in at those points. It's inevitable. It's just how electricity and electromagnetism work.

    There are some things you can do to work around it. Environmental noise can mask the electrical noise from the speakers. Using the audio out jacks with headphones or external speakers eliminates the wiring that picks up RF noise inside the chassis. Using a USB sound card moves audio decoding entirely outside of the chassis.

    I have. Even when I had gone to 4.4 or 4.5 all cores before de-lidding, I was getting 76 tdp tops. So yes, the tdp is lower than the max and won't become a concern unless doing mods to run higher multiples. The average user will never hit the max tdp!

    Doesn't mean that other models don't have problems. I've had problems with every notebook I've had my hands on: Acer, Apple, HP, Lenovo, Dell, Leading Edge (remember them?), Toshiba, WinBook. Probably others that I've forgotten about. Noise from every one of them. Some more than others, some less than others, but every single one. Why don't more people complain about them? I dunnow. Maybe it's just because most notebooks have worse things wrong with them for buyers to latch onto.
