    NP8265-S USB Power Issue

    So I acquired a friend's NP8265 and it seems to have a problem with USB power. Whenever I connect a phone through USB it doesn't work, but instead it will go on and off continuously. I have tried different USB devices and the only one that seemed to trigger the issue is phones. I thought the problem might be high power devices but then I tried using an external HDD, my G500 mouse and a keyboard. Non of these devices faced any issues even while having two or more connected at the same time.

    I cannot understand the source of the problem but I tried reinstalling drivers, using different ports (2.0/3.0), and also tried using Fn + Power button but it didn't work and the laptop just went off afterwards. At some point windows indicated that the USB device is not recognized, but I couldn't tell exactly how to reproduce this and this only occurred on one of the 3.0 ports. The laptop is running a pre-installed windows 7 premium.

    Any advice?

    -CORE i7 4700MQ 2.4 GHz
    -16GB DDR3 1600 (2 DIMMS)
    -2.5" SATA 750GB(7200rpm) HDD
    -AMD RADEON HD 8970M W/4GB
    -BIGFOOT 1202 AGN+BT 4.0
    -WINDOWS 7 HOME PREMIUM 64 BIT

    Turned out to be a problem with the USB cable. Although the one I'm using works with other devices (tested on various of laptops and desktops), it's not a genuine cable. So I went and tried my genuine USB cable and it worked well. I still think there is a problem with power but at this point I guess it's negligible.

    Hope this helps anybody who goes through something similar.
