    Power Supply Issue


    Wasn't sure where to post this (slightly off topic but I figured someone on here would be able to shed some light on this). I have an HP DV7-4285DX laptop, the machine runs Windows 7 Home Premium and is performing quite well after a good weekend of "De-OEM'ing" (uninstalling the crap it came with), however the power supply is doing something I've never seen a power supply do. Yes, it gets warm when its plugged in, but I've seen that before, however it also makes a faint high-pitched whining noise when its plugged in. HP is replacing it under warranty free of charge (had the machine only a week). So my question is, is this normal for a power supply to do this or is that power supply defective?

    sounds like a defective power supply to me

    The fact that HP is replacing it under warranty would seem to indicate that even they think something is wrong. It's been my experience that many manufacturers are reluctant to replace things without first going through a lot of red tape to make sure the warranty wasn't voided in some way.

    BTW - Welcome to the Forum ... both of you.
