Before I sell this X100e on ebay, I thought I'd try and restore the system to its original state - how it came out of the box - and start again (or reformat and put on XP Pro), but I can't find anyway to do this (no Thinkpad Button, and the info says nothing about how to do this!).
Restart and press F11
to invoke the Rescue and Recovery
Restart and press enter. It will show you a list of options, select then F11
for Rescue and Recovery
I am sorry to hear about your situation. I feel almost the same way regarding temperature and battery life.
However to be fair, battery life improved a lot (from 2:45 hours to 3 and almost 4 hours) after resetting my X100e using Rescue and Recovery. Something was draining the battery out of the box and was fixed after applying Rescue and Recovery. Nevertheless, 3 or 4 hours is not competitive when compared to other size equivalent laptops.
Regarding speed, mine is quite capable (double core probably makes a difference).
Lenovo Support, when answered from a country different than the USA, is deplorable and mediocre.
They only follow a script. It is very funny when they repeat after you what you just say to make sure that what you just said is what they just hear and want to confirm it. In my point of view they are not knowledgeable at all when referring to technical specific questions out of their script.
Only real and good support is when you are lucky enough to be transferred to USA technical support or when they send you via email a message with a phone number that connects to a USA agent.
Forums like this one are far more helpful than Lenovo technical support.
Thank you all forum posters.
However I believe that it is important to complain and report to Lenovo the issues mentioned in your post, so it starts to make it to the top of their list in order to be seriously addressed by Lenovo engineers.
