    by jean luc ferre
    Hello,
    on this laptop hp g72 b52sf i have screen problems as you can see with the photo joined in attachments.
    the used graphic card is "intel hd graphics" and the id of the integrated screen is : "monitor/SEC3354".
    i verified the driver of the péripherals and they are ok. i verified the definition and settings of the graphic card and of the screen : definition 1600x900 and refreshment frequency :60hz. (they are the sames for the graphic card and the screen).
    i don't understand the reasons of the white stripe at the bottom of the screen below the task...

    USB problems?
    by Hondaman
    Recently I discovered my SSD died (OCZ/Toshiba 240 GB). It was in a USB enclosure, attached to the Linksys WRT-AC1200 router. Since then I removed the USB enclosure and attached it to my Win7 PC (AMD 8150 CPU, 970 chipset, 64 GB RAM). I also gathered one or two other USB enclosures to figure out what is going on.

    (I suspect that I lost quite a few MP3 and FLAC files I recently ripped from my audio CDs, I think I lost very little un-replaceable stuff.)

    I think it is IMPOSSIBLE for Win7 to have any problems with a USB enclosure as long as Win7 knows how to speak to the...

    Behringer Eurolive B205D repair - help identifying transistor
    by magneh
    Hello
    Got this speaker from a friend , defective. Power led comes on and off , in a loop.
    Disassembled, got the board out, and after a bit of measuring I found a low resistance on a 5v6 line. With a bit of current I found a transistor heating up on that line (labeled T1 and 113 as on pic).
    After removing this guy, I got a value of 0.7 in diode mode on that 5v6 line, which before had 0.02 or something like that.

    I tested powering it up without the IC, and the speaker turns on and stays on, and works fine

    Still, I need to replace this transistor....

    Lenovo 11e problems (any sata hdds are not recognized, sleep battery drain)
    by clabr
    Need help to solve some problems with this laptop.

    After working in bed with it one night and heating up too much (probably the cause of this problems) the sata HDD OS windows froze
    After restart the original Sata HDD was not recognized anymore (but works fine in other laptops or PCs)

    Tried connecting other good Sata 2.5 HDDs but not one is working in this laptop anymore (not the original nor others)

    Before this had happened I observed some other problems:
    When I tried replacing original mecanical HDD with a SSD HDD could not get them...

    help to identify transistor msi ms-15ck1
    by elsomer
    hi people, i need some help to identify a transistor(q14) that is missing on the board, so the gpu has no voltage i think that q14 activate the phases for gpu, but i dont have schematic or boardview, but i think its the same transistor than q15 and q16, thanks...
