You can go from 207 straight to 214.
Motherboard change doesnt really phase me, just would prefer an easier option.
2) I get what you're saying but having a car that runs for 30mins is better than having no car at all, especially if you only want to do a 30min trip
I'm definately of the opinion its a universal chip thats been used on the board somewhere which is the problem, google throws up loads of people with similar issues from laptops to desktops https://www.google.co.uk/search?q=co...exactly+30mins
Trouble is many folks think its some kind of OS power setting but its not.
Think I'm on a hiding to nothing but I'll try the BIOS upgrade
You can go from 207 straight to 214.
Right so thought I'd give an update on this mess so after updating to Bios 214 as suspected it made no difference what so ever and still it shuts down on exactly on the 30min mark
So I started looking about for a new MOBO for it and found a complete tab minus the keyboard for the same price as a MOBO
This new/2nd hand unit seems fine currently, it is slightly different mind.
The old one is speced as below
CPU is Z3775
Bios is T100TAS.207 14/05/2014 (now has the updated Bios of 214)
This replacement is spec'd like this....
CPU is Z3740
Bios is 304
So whats the difference ?? it does seem the processor speed is a tadge slower @ 1.33GHz compared to 1.46GHz of the old one.
I am assuming the new/2nd hand one is a slightly older model ? yet the Bios is a higher number ??
Intel Atom Z3775 vs Z3740
Replacement is a TA not a TAS & has older BIOS, latest is 314.
BIOS numbers don't mean too much, look at the BIOS date.
BTW, someone else had the same shutdown problem with an Asus desktop. It was the motherboard.

Right so the replacement is an older unit and apparently shouldnt be as good, yet I've checked the pair and the replacement is faster ?
I've rest both Tabs to factory now so they are exactly in the same state. There is something very odd going on with my original which should be the better of the two. From a cold restart the original takes 30sec's to get to the log in screen, the replacement takes a mere 12 seconds.
The replacement seems far more frugal with the battery, both have exactly the same settings yet the original has a nasty habit of munching through the battery at an alarming rate when in standby, where as the replacement barely sniffs at the battery when in standby.
I've never got more than 24hrs from the original one when in standby, I tended to just put it down to it being a Win 8 tablet and I tended to shut it down completely to save the battery, but the replacement tab has done 36hrs and a bit of surfing and its only at 56% now !!!
The replacement feels completely different, looks to me like my original has always been a bit of a sick tablet and I should have sent it back, but not knowing what a good one felt like I was none the wiser. Theres something the originals doing that the replacement isnt I feel.
Yes there are many folks who have suffered the 30min shut down issue, the best I've found is its a rouge chip that was used at sometime on a number of boards which does a check after 30mins and if it doesnt like something it kills off the power.
Boards effected seem to be ASUS, ACER, DELL to name 3
Z3775 has a much higher turbo frequency.
Your power options advanced settings may be keeping it a maximum all the time. Look for Processor Power Management.
Mine was set to 100% for all. Need to reduce it when sleep or sitting idle.

Although that doesnt explain why the 3775 takes so long to boot from cold and its general sluggish response, both are running stock Win8 from the inbuilt ROM
Interestingly since finding this older unit I've been using it way more than the original ever got used because its so much more usable now.
