Had the same problem with a manufactured refurb, would go to 79 %, if you go to power options, change plan settings, change advance power settings, then to the Lenovo energy management tab, press the big enable Lenovo energy management, click on the blue gear to the left of the question mark, if "Optimize for Battery lifespan" is selected it will only charge the battery to 80%, change this to "Optimize for Battery Runtime" and it will charge to 100%
use the onscreen keyboard or an external keyboard to log in to your computer. the issue for your laptop getting switched off automatically could be due to different reason, is your laptop over heating? did you make any changes in the computer?
Internet broadband connection is much more faster because it is directly connected via physical connection from the modem (typical setup for home use). But now a days wireless internet can now compete with DSL thru a 3G/HSPDA network. In our country we can have a maximum bandwidth of 2.5Mbps using 3G wireless network.
Yes you can speed up your connection using your phone as a modem but you need to consider some aspects.
your phone is a 3G capable phone
you have 3G network signal that an indicator "3G"can be seen next to the signal meter of your phone.
your network provider has 3G services.
What happen to you most likely is that your are connected using only a GPRS/EDGE. This is equivalent to a dial-up with maximum of 56kbps transfer rate. There is a great gap between the two if you compare it.
I already tested mine with maximum receive/downlink of 2,501 Kbps. I was really amazed.
Hope this things help you. If it does, please rate me.
Try to hold down shift several times and reboot your computer. As soon as you see the lenovo sign shift again till you get to safe mode.. This might allow the monitor to stay on to trouble shoot ...If not you will have to call lenovo.

it sounds as if its over heating.
the first thing you should check is to make sure the fan is running and even if it is try to clean out the fan.
or it could be that it needs the cpu heatsink paste replacing.
go to this link this will show you how to do it. How to Apply Thermal Paste .
all this is not to say thats what it could be,its just to say it might be the fault.
this could be a couple of things wrong.
1.i would try another power cable first.
2,can you hear if the fan is trying to run if not then you may need to take it to some one to have a look at it for you.
