Question 1

What is the red dot on the keyboard?

Accepted Answer

Short answer, it is another way to use the mouse. Imagine a small rubber dot, that when lightly pressed in the direction you want the mouse to move, it moves.

It works very well, not sure why other companies don't use it. A big benefit is having the ability to move the mouse with out moving the hands from the home row keys.

cheers

Question 2

does this machine run windows 7?

Accepted Answer

Yes!  It comes with Windows 7 installed with a disc containing Windows 8 if you want it.  I stayed with Windows 7 Professional.

Question 3

My agency management system only runs on Windows 7 yet this says it has Window 8 as well.

So I am confused. Already bought a Surface Pro before I realized it was Windows 8 and my system would ONLY accept Windows??

Accepted Answer

It comes with a windows 8 upgrade disk free of charge .  The windows 8 is not installed.  I work in medicine and nothing works with win8 yet so all things must have win7.

Question 4

Does the laptop come with Microsoft Word, Excel and Power point?

Accepted Answer

Short answer: no

It comes with a limited trial of office, actually anyone can get the crappy office 365 or office 2010 etc for a trial.  Then Microsoft wants your credit card 30 days later.

If you opt for 356 you'll never ever stop paying for it....

Question 5

Does the lenovo E540 windows 7 support the touch screen?

Accepted Answer

No.  I'm told Windows 8 will but I don't know if the hardware will.

Question 6

Does this have a TPM chip?

Accepted Answer

has small electric as you are typing tried to get it addressed but the return to them would entail their keeping the laptop for minimum of 1 wk which was unfeasible for me, and repair locally was the same problem.

Question 7

Is this really a quad-core processor? Other sites selling what appears to be the same product state that it is a dual-core.

Accepted Answer

It is a dual-core with hyper-threading, so four threads.

If you google search for "Intel Core i5-4200M 2.5GHz" the Intel specs will come up (NewEgg won't let me link)

This chip is geared more for mobile, and energy efficiency.

Question 8

I've seen some similar models that have fingerprint readers built in for security, and I think I see one in the pictures for this model as well but it's not labeled. Does this laptop have that capability?

Accepted Answer

I bought one of these a few months ago, and it does have a fingerprint reader.

Question 9

does this have a RJ45 net adapter ?

Accepted Answer

Yes it has an RJ45 port on the right hand side.

Question 10

I want to buy a replacement charger. Which charger is the one that comes with this laptop (i.e. what is it listed as on Newegg?)? I can't find it anywhere on Newegg or Lenovo's own website. Thanks!
