          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...

          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...

          Powersupply has all the voltages - Monitor still no power
          by Capacitorial
          Hello guys,

          I have a Philips 240B7QPJEB. The monitor seems completely dead.
          I opened it and measured the voltages of the powersupply. I found that a mosfet was dead and replaced it.
          On the connector, that goes to the TCON board, all voltages 15-19V and 5V are present.
          The small connector on the left of the PSU has two cables with 18V and all the other have 0.2V. It connects on this small connector on the left ontop of the panel. I guess the backlight? Seens fine I guess.
          The weird thing is, that the Power LED is powered over the TCON board.
          On The TCON...

          PS4 Power Button Traces
          by jeremy96
          Hi everyone,

          I recently bought a used PS4 and discovered that the power button is broken. Upon closer inspection, I found that the traces for the power button on the PCB are damaged and torn.

          Does anyone know where these traces lead or have any advice on how to repair them?

          Thanks in advance for your help!​...
