USB power question
I have two PCs in my office: self-built mATX tower & HP TouchSmart IQ506. I also recently bought a WD My Passport Essential SE 1TB portable hd.
Yesterday I plugged the new drive into the self-built pc. It didn't work. Tried the ports in the front of the case and those on the back. Then, out of curiosity, I tried the drive the TouchSmart. It worked normally. What is the problem with my self-built pc not putting out sufficient power for the drive? The specs of the pc are below. I have had this happen before with older portable hard drives, an inland sata/ide usb drive adapter and a 2.5" ide drive enclosure. All these devices except the usb drive adapter are powered from the pc. The adapter has an ac plug. It is a psu problem, a mobo problem, both or what? links of my devices are below: Amazon.com: Western Digital My Passport Essential SE 1 TB USB 2.0 Portable External Hard Drive WDBABM0010BBK-NESN (Midnight Black): Electronics Jim do little: Inland SATA/IDE Combo Drive Adapter USB 2.0 ASUSTeK Computer Inc. |

Have you tried other USB devices in the ports?
If you suspect PSU, I suggest taking the PSU from the Touchsmart and putting it in the other machine. |

TouchSmart is AiO so I am reluctant to mess with it since it is fine http://www.hp.com/hpinfo/newsroom/pr..._iq506r4nq.pdf 3. Hardware from custom & TouchSmart are not interchangeable 4. I don't know what to suspect here... |

I'm, sorry, I didn't realize the touchsmart was a laptop.
What is your current PSU like in your desktop? |

So from what i can tell when your computer sleeps it uses less energy to get in and out of sleep mode but uses more power in sleep mode, while when you hibernate it takes more power to get in and out of hibernation mode but uses less power in hibernation mode. Following that, at which point does... |
