Hi I have a new Asus Transformer T100 that has nearly driven me mad as does most windows products ...

I have discovered that my Asus Transformer tablet does not support S1-S4 state sleep through powercfg query ...

Why is that?" How can I change that? Should I return it?

Have you asked ASUS support yet?

can I ask what you want to achieve?

this model supports InstantGo (formerly known as Connected Standby in Windows 8)

My samsung windows 8 hybrid uses connected standby, its 2GB 32bit model, I don't believe 64bit is currently suported, you haven't reloaded 64bit have you? (Probably not otherwise it would probably be using S3 sleep)

I'm asking Asus but they're shut at the moment. Thought perhaps out is normal for tablets to do this but yup will ask Asus when they are open

I want to achieve the lowest power consumption when I'm not using it!

thought i'd summarise what my international adventures have discovered

1) windows 8.1 tablets have what's called "connected standby/standby connected" which is a state of sleep that SHOULD achieve 5% battery drain per day giving at least 20 days of standby per full charge.

2) this may be called all sorts of things by manufacturers eg ïnstant go. tablets that have this mode is technically not compatible with normal sleep modes and negates the need for hibernation. hence power behaviour is very weird

3) it's weird because it doesnt always work. some people complain of battery drain of 100% within hours with their tablets. sometimes the wifi stays on (very common) although it really should be off to achieve max efficiency. for me even my keyboard dock and dock USB 3 stays on! hence marriage of software and hardware drivers is problematic at this stage (i don't see it improving really, look at android, always have always will be a minefield)

4) my tablet has just had every single driver and bios updated by ASUS. i don't have time to do any sleep testing but it seems my tablet actually sleeps properly despite powercfg not reporting any sleep or the wifi and keyboard dock stays on, i can achieve very good standby times (haven't had time to measure).

if the 2014 ipad doesn't improve on its functionality watch out!

Seems like it's normal behaviour, and Connected Standby supersedes the S1-S4 states on this system?

I didn't know about Powercfg until your post, an interesting utility. There is a good section in the Scott Hanselman post about the /sleepstudy parameter for connected standby devices

Its called Connected Standby in Windows 8 and has been renamed to InstantGo in Windows 8.1

Interesting. My ASUS supports ConnectedStandby (PowerCFG seems to be using the old name), so I removed the hibernate file (powercfg -hibernate off) and that saved me 2.5GB on my SSD...
