    My usb ports have ZERO power and my card reader is powerless:confused: Whats the cause here? I just did a fresh install cause before i had a similar prob, but its still here:mad: Is there a internal part thats broken?You guys just gotta help me this is giving me one king sized headache. Before any plug in devices would freeze explorer.exe now they dont even work, seems things only get worse for me.There are to many problems for me to deal with here,no amount of clean installs have been able to fix these the parts.
    My cd drive cant erase cds that i made, but it was possible in vista.ive had my laptop for a year and a half.myabe its time i get a netbook instead.

    Could be something is broken, or just a missing/botched driver.
    Or a dodgy power plan.

    Power Plan is balanced? (nothing like the Vaio battery saver plus)

    No warnings in Device Managaer indicating potentially bad drivers?

    No every plan has the same result, i dont see any sd card driver in device manager, i could show you a desktop pic of device manager.

    In the pic theres no usb ports and no sd card.

    Interesting...

    I have a USB controller listed... you lack it.
    I'm not sure how to est for dead hardware.
    But try reinstalling the USB drivers...

    One more thing - check your BIOS if there is the ability to disable/enable USB.

    Dell locks most bios stuff, and windows usually dl usb drivers for me.i would take a peek inside but to get to the usb ports i need to remove the screen,keyboard,plam rest,screws,engine,and so on.Thats a little out of my league.

    Hmm, I'm out of ideas at this point...

    I suppose you can always try Dell - but assuing it is hardware, it would be expensive to repair if out of warranty :(

    You're welcome - I mean, maybe someone finds a solution - but it really seems like hardware to me.

    Never take no for an answer
    If your USB is out and your media card reader is out, the problem is clear

    All media card readers run off the USB bus, so when you short the media card reader, you overflow the hub, causing it to fail.
    If you take your laptop apart, you can target the USB hub and replace it.
    A USB hub, such as a TI, Broadcom, Ricoh, etc costs less than $1 when you buy them from digikey, or mouser.
    You need to take your laptop apart to find out what the model of your USB hub is, buy the same one, as a replacement
    You should also buy some solder wick, and Kwikchip
    The wick will allow you to remove the solder from the multiple contacts of the USB hub (usually 16 contacts)
    Kwikchip takes a long time to cure (its like super solder) and will allow you to solder all 16 leads in one shot

    You should probably get used to using a soldering iron, or find someone who knows how to use one.
    2 Hours and $10 of parts will get your system working as good as new again

    Wow i dont have the slightest clue what some of that stuff is, im not good with taking things apart. The furthest I've ever got was replacing the ram and replacing the wifi card with a 4965.I might consider that, once i look some of it up, also I've never used a soldering board before. i restarted and windows found usb drivers but it still cant read more than 2GB cards.My 8Gb card desnt work though it just says do you wish to format.
