    After the factory reset, the interrupts generally sit around 0.1%. Someone in the Asus 810C thread commented that he also noticed the interrupts process on his device and that it sits around 0.1%. A certain number of interrupts is probably normal.

    I may try reverting to a previous bios.

    Chrome (both metro and desktop) may be power hungry. Please, take a look at this chrome issue: Issue 153139 - chromium - Google Chrome is not battery friendly on Windows - An open-source browser project to help move the web forward. - Google Project Hosting

    In order to check it, you can do the following check:

    - run powercfg /energy at the command prompt
    - copy file C:\Windows\System32\energy-report.html
    - edit file. The clock tick rate should be 15,6 ms.

    If you observe a lower value, probably chrome is changing the clock, causing lot of interrupts that prevent the processor to enter into low consumtion idle states.

    I've observed this problem (other people too as commented in the above chrome issue) after playing a youtube video in a laptop from chrome. When playing videos, chrome (possibly other applications) lower the tick rate in order to prevent lost frames. When video is not playing the tick rate is restored to its original value, but chrome does not always restore it.

    My laptop (core i5) shows 0.1 cpu (system interrupts) even when chrome has lowered the clock tick rate (see my previous post), in TPT2 it should be a similar number.

    Have you issued a SPR to Lenovo?

    For those that have their tablet, how is the windows refresh/reinstall handled? Is there a separate partition for the window reinstallation? Is there any way to transfer this to a USB drive, similar to the recovery app Acer has for the W510? Hoping we can reclaim this hd space.

    Only the 32 Gb model apparently has a flash recovery disk. It seems like there is a recovery partition in the 64 gb model but I don't see a way to put it on a flash drive. With only the OS and Lenovo software installed, you have about 34 GB free.

    I am still sitting on the fence between tpt 2 and helix. If helix does not come in Q1, I will probably go with tpt2.

    Does the Helix come with a digitizer? If it does, I may return the TPT2 and get it but I was under the assumption it didn't.

    I think it does, but it's a different animal: i core cpu but weights more than 2 LB (1kg), and more than 3 LB with keyboard.

    I guess this is off the topic and I will stop.
