For those of you who have the Samsung Slate 7 that Microsoft gave at Build (or that you purchase yourself!), and who are travelling: I hate to take chargers for all my gadgets, especially since my Windows Phone, my Bluetooth stereo headset and my Kindle (amongst others) all use micro-USB to charge. So I just take a couple of micro USB cables and I can charge my devices from the PC.
However some laptops are cutting off power from the USB ports when they go to sleep. I thought it was the case with the Samsung Slate 7 too (the plugged-in phone will stop charging if you make the slate sleep). However I found out that if you unplug and then re-plug the USB cable, then the charging resumes and you can charge the whole night as needed
This is a convenient travel tip, and maybe will be useful to some travellers on those Christmas and New Year holidays. I take the occasion to wish all my readers a happy Christmas time and hope that you can all enjoy a bit of rest!
