    Is it normal for my power brick for 7805 to make a hissing sound?

    After a few hours of my laptop being plugged in to that power brick (the one with green light), i notice the power brick gets VERY VERY hot, and it then makes more like a hissing sound or buzzing sound. I then have to unplug it for it to stop?

    Is it normal? or should i get it replaced?

    Its common, but that doesn't make it normal. a number of people have called gateway and been able to get replacements having similar issues to yours. Mine definately doesn't get hot when plugged in for a long time, but I don't game on it really, if you aren't loading the machine heavily when its happening there's definately an issue.

    Mine hisses as well. Usually after prolonged use. I thought it was some hardware at first and started to freak out! i was searching around my computer like "where is that coming from?!"

    No- my 7811 and 6860 bricks are both completely silent. Hissing is not air leaking inside, it is electricity leaking inside, and the heat is from the bad component - there's resistance building up and that makes heat build up, which makes resistance build up more, etc. Sooner or later, something very bad is going to happen to it and possibly to your laptop to which it is attached.

    I'd get it replaced ASAP and keep the computer use to a minimum until the new one arrives.

    When this line of laptops (p-fx) was first released this forum had numerous threads about hissing power bricks. Not sure how many people got them replaced but I never read a report of one causing a problem with the computer, I for one have just ignored it and its never given me a problem.

    Can somebody give me a link to a Targus that is under $60? I can't find a cheap one. I posted the same thing on the thread about 180 Watt bricks, but I haven't got any responses.
