Question: Does the keyboard have to be charged separately from the tablet or can I charge the tablet only while docked to the keyboard?
Document: I tried the T100 consumption in standby, and it consumed about 6% in about 7 hours of standby. I used the notebook 100% charged for 1  hour while it was plugged into an outlet, and the charge never dropped below 100%.
I've updated some information based on those tips as well.1. You'll be extremely eager to use your T100 out of the box. Don't. Use it, that is. You can be as eager as you want. The user manual -- apparently updated recently -- specifically states the device must be charged for a full 8 hours prior to use. Charge it. 8 hours. No less.2.
The laptop is charged through the micro-USB port. This would not have necessarily been an issue but for the fact that, unlike conventional laptops, the T100(S) needs to acquire some (~10%) charge before it starts and is usable.2. The battery has been of a little concern. Starting with a 100% charge, the behavior has been inconsistent. At times, it will hold its charge in standby for 4-5 days with very little decay.
I have been playing around with settings in Win8.1 as it seems that the batteries have the potential to hold a charge for a long duration. (See Tips below)3. The dock connection is still a little flimsy as the 2013 model. Even after the tablet has clicked into place, closing it over the keyboard seems to press against the dock release button and causes it to slip out of the dock.
I start using the tablet saturday night for about 2 hours with the original charge from factory (turned it on at 100%). Cup of configurations, WiFi, the essencial. Turned it off with 97%.Then Sunday: started again at 11 am next day. Copying from my external 500gb HDD to the keyboard (it has a blue 3.0 USB port) about 250/300gb of several files during day (video, images, exe, etc). Mostly with the keyboard connected.
The size, price and performance are outstanding! Keyboard is big enough, and tablet with keyboard is still very compact. Only complaint is that it takes 8+ hours to charge.
APPLE?You get the Pad, the keyboard and the charger. Contributing to that -1 is that the alignment of the micro USB port was pretty poor on my unit. Plugging in the charger so forced I rechecked it 10 times to make sure I had it oriented right. I'm used to my old ACER where I just drop it onto it's dock to charge it. I hope I can find a similar dock for this guy.
Windows home and student...MSFT office included for no additional charge!!!5. 500 GB HDD. I find myself using the dock more than not and the added space is quite welcomed.6. Keyboard dock is not a separate item for purchase.7. Very light and portable8. Very responsive and versatile for the price. You can run multiple apps in the background and switch between desktop and start screen without issue. I am very surprised how well Intel's Baytrail CPU is performing.
I got this tablet but is better than I expected easy to use light and the charge on the battery is longer than my older tablet I recommended
You are dead in the water. Kaput. Nothing. Nada.UPDATE same dayWhile preparing the machine for return to Amazon, I disconnected the dock and turned it on. Voila! It did turn on. The battery was fully charged. And when I connected the dock, it worked too. This gave me the opportunity to remove my files and programs. In the process, I discovered that, while the touchpad on the dock works, none of the keys work.
Answer: no, the keyboard doesn't have a charging port, or a battery.  I should also mention that, when docked, the battery drains faster when the unit is in sleep mode,  so when you're not using it, and not charging it, you should undock it from the keyboard.  Just FYI.
