Hey guys,
I have a Samsung NP-Q430-JSB1US notebook. It is running an Intel i5 processor with the Nvidia GeForce M310 graphics card and 8 GB of RAM. The operating system is Windows 7 Pro x64. I have had my computer shut off several times during the last few months and have finally localized the problem to only when I have a chargeable USB device connected to the computer (I can use other USB devices such as cameras and hard drive enclosures just fine). Most notably, the problem occurs when I connect a Cisco Flip digital camcorder, but I recently bought an iPod Touch and it does the same thing during periods of heavy syncing.
I have Core Temp 0.99.8 installed and have verified my suspicions. When I connect either of these devices, temperatures skyrocket to the magic Tj. Max of 105 degrees C. This computer normally runs a little hot anyway, about 55 degrees C under no or very little CPU load. Under device manager, USB root setting under system devices, it lists my USB port as 500 mA. I have yet to find any specs on my devices, but I can't believe that they would individually draw more than .5A. It looks like the keyboard and mouse devices come off these low-power ports, as well as all 3 USB ports, one of which I always use for an external Bluetooth USB adapter. Tried removing it to verify it wasn't causing the problem, and the removal had no effect on the skyrocketing temperatures. According to Wikipedia's page on the USB standard, there appear to be "low-powered" and "high-powered" ports, which really didn't make sense to me the way they explained it.
The notebook is not having any issues running normally high CPU/GPU-intensive programs, such as video conversion or playback. The only upgrade I've done to the machine is increased the RAM from 4 GB to 8 GB. I thought this might be the problem, so I reduced peak processor state from 100% to 90% while I use the Flip. The iPod Touch still overheated using these settings, and in order to sync my library, I had to reduce this setting to an unbelievable 25%!!! I do NOT overclock this computer.
I have never seen anything quite like this. Am I experiencing hardware issues, or am I trying to draw too much power from my USB ports? Since I didn't even know that there were different types of power-ratings on the USB ports, I figured I would consult the experts. Has anyone else experienced anything like this before?
Thanks for all of your help in advance. This forum is always a great place to start for my computer woes.
