The sleep-and-charge USB port feature of Toshiba laptops is interesting. One can use the relatively big laptop battery to charge cellphones, mp3 players etc.

I have seen this feature mentioned for Toshiba laptops. I was wondering if another manufacturer provides the same feature, possibly using a different name.

My Acer 5735 laptop also powers the USB ports while in sleep mode. –  Linker3000 Oct 11 '10 at 8:28

The Dell Latitude E series has this feature. They call it Powershare

I had occasion to use my brother's Acer Aspire One netbook (the one with an 8G solid state drive) and noticed that it powered its USB ports when in sleep mode. So I imagine that this feature is somewhat common. Good to know. –  Bill Rodman Feb 16 '10 at 18:35

most ASUS Eee PCs have power on the USB ports even when turned off.

although the nice folks at shlashgear call this feature a "a true stroke of innovative genius", many users i know consider it a pain in the behind as it drains the battery when you 'forget' to unplug a device that is drawing power. :)

I have to agree with you there. One man's feature is another man's bug. –  Bill Rodman Feb 16 '10 at 18:37

I have a Toshiba netbook and find the "sleep charge" port to be a big help when my smartphone starts to peter out during a long conversation (just plug it into the charging port and leave it in my bag, with the netbook, while I talk on the Bluetooth headset). Always had about 5 hours of juice left, more than enough to do my computing. This is defiantly unique because the computer can do this while completely powered off, and drawing no power. I tried to do the sleep mode thing with another laptop because my phone needed a boost, and the computer became very hot while in my bag, and was almost depleted when by the time my phone was charged. To the best of my knowledge, Samsung also offers this feature on a few of their netbooks, and notebooks. BTW I have owned this netbook for about a year.

Apple laptops do this as well.
