My ativ 500T along with win8 defend this partition like independence.

On my win7 laptop, I just use a command line utility called diskpart, pick a partition I want, "set id 07 override" and voila unhidden and accessible, pops up in windows explorer.

I'm not a hard drive & data storage guru, but it seems to me something has been changed in the way windows 8 manages disk space - at least on clovertrail devices.

My interest is in getting OEM drivers out of this partition, without doing an actual recovery. ]]> Windows 8 citizen-x http://forum.tabletpcreview.com/windows-8/56949-access-recovery-partition-diskpart-vs-gpt-drive.html <![CDATA[[sleep/wake/connected standby/battery drain issues]possible solutions]]> http://forum.tabletpcreview.com/windows-8/56912-sleep-wake-connected-standby-battery-drain-issues-possible-solutions.html Fri, 17 May 2013 21:23:50 GMT TO MODERATORS & MOTIVATIONS
This is a partial port of my post from answers.microsoft.com forum, which - as I came to realize while dealing with MS support - is far inferior to tabletpcreview in terms of helpfulness and professionalism. Also there's probably more people with such issues searching for help at tabletpcreview than MS answers - and since tabletpcreview helped me a lot with my 500T, I'd like to give something back.

The original of this post can be found at [WINDOWS 7,8][SLEEP/WAKE/BATTERY DRAIN - Microsoft Community - this constains feedback to MS on the power management and connected standby in win 8. The original at answers.microsoft.com will not be updated from now on and this is the place I'll be posting my tips.

And I'm somehow sorry for using caps in the title, but a lot of people have such problems with windows 8 tablets,so - might I suggest a sticky?

TROUBLESHOOTING - GENERAL
Quite possibly you have a driver or service that prevents the device from sleeping. Nice explanation here with possible solution (example) - Jason Hartman Consulting: Windows 7 PC won't Sleep automatically - An audio stream is currently in use

Run command prompt on admin priviliges - start menu or screen, cmd, run as admin. In cmd, powercfg /energy - this will write you a html file to windows/system32 with report on power issues - cut this file, paste somewhere else (you can have problems opening it from windows/system32) - look for any red highlighted error sections there, those prevent sleep.

On ativ 500T and Vivo Tab, be sure to disconnect the keyboard dock before running cmd, powercfg /energy.

Possible solutions here - you can bump on "srvnet" (remote clients and windows media player sharing) - try going to Network and Sharing Center in control panel and disabling any sharing in advanced options (left menu). Also, services.msc, here disable windows media player sharing service.

Also, in my case it was Intel SST Audio Device/Realtek I2S (these two are interconnected somehow) - it means an audio stream is open/not closed properly. Example - google voice addon in chrome can prevent your pc from sleeping - but it could be anything, adobe flash content in the browser, app - like Steam, or an alternative virtual keyboard for example - TouchPal for windows 8 is fine though, checked this one, it's all clear. More - VLC, file sharing apps...

For this Intel SST audio device, simple workaround is to shut down volume to zero% - more sophisticated solution here - Betreff: Poor Connected Standby Battery Life on TP... - Page 3 - Lenovo Community
Also, in control panel, device manager, in properties window of any device, make sure there is no device that there is allowed to prevent the computer from sleeping. Example: device manager, sound,video and game controllers, Realtek I2S, right click, properties, power management, "allow computer to turn off this device to save power" (YES), "allow this device to wake computer" (NO).

For a list of devices that can prevent sleep:
cmd, powercfg /devicequery wake_armed
Even if you have no devices that can prevent sleep, you can still get sleep prevention requests!

For a list of requests for preventing sleep:
cmd, powercfg -requests

For a list of wake timers (those can automatically wake your computer too):
cmd, powercfg -waketimers

For information on last wake and it's causes (if the cause info is available):
cmd, powercfg -lastwake

And again, report on power management with possible culprits highlighted in red:
cmd, powercfg /energy

To override sleep prevention requests (case sensitive) - example on the 'srvnet':
cmd, "powercfg -requestsoverride driver FileSystemsrvnet system" - might not stay after reboot.

Btw, powercfg command line options - Powercfg Command-Line Options

To sum up - possible culprits and solutions:
- audio device - in my case, shutting down the volume to zero% removes the sleep prevention hook and allows the tablet to sleep
- srvnet - windows media player sharing, remote desktop, public folders - disable all these + windows media player sharing service in services.msc. Also, being member of a network homegroup can be an issue.
- adobe flash content in the browser - close the tab, preferably with the browser itself
- google voice addon in the browser
- disable google chat on iGoogle - remove it from iGoogle (if iGoogle even still exists? I'm basing this on an old blog post)
- basically, could be anything - infuriating, huh? And this is exactly what I mean by unintelligent (euphemism) operating system design.

TROUBLESHOOTING - TASK SCHEDULER, UPDATES, ANTIVIRUS SCANS ETC
If you have huge battery juice loses during the night, on sleep or "connected standby" (using "" cause it's just marketing BS not working as it should) - it's possible you have a scheduled task in the Task Scheduler or a routinely activated service/activity - a task that kicks in an then repeats regularly the whole night - and possibly one that was auto-added by some program without you even knowing it's there....

Open Task Scheduler and look at the list. It could be google update (got chrome?) that kicks in at 01:00 at night and then repeats every hour even if you're on battery, and EVEN IF YOU'RE SHUTDOWN. Could be scheduled antivirus scan (say, MS security essentials - here, you may have to disable scanner completely, same for windows defender) or sth else.

TROUBLESHOOTING - WINDOWS 8 CLOVERTRAIL TABLETS - SAMSUNG SMART PC 500T, ASUS VIVO TAB TF810, LENOVO THINKPAD TABLET 2 - suggestions dated on April 2013

In the particular case of the new windows 8 tablets based on intel clovertrail SOC - quite oftentimes sleep/wake/battery drain issues are related to faulty (crappy) drivers. For the rollbacks suggested, I provide skydrive links lower on for the older, suposedly better versions.

- bluetooth - on ativ 500T - solution is to rollback from 12.0.0.3600 to 12.0.0.2200 - a long but valuable discussion here - win 8 samsung ativ smart pc BSOD. please help - Microsoft Community
- sd card - on ativ 500T - "solution" is to not use sd card...
- intel graphics drivers ("Internal VGA Intel") - on Ativ500T, Vivo Tab TF810 - solution is to rollback from 9.14.3.1128 to 9.14.3.1087 - the referenced discussion on bluetooth also has intel graphics driver talk on page 2.
- in case of TPT2, somehow it's often not drivers, but rather that old thing with sleep prevention management in windows - so basically the stuff from TROUBLESHOOTING - GENERAL section - and TPT2 people, you might want to have a look at this discussion - Poor Connected Standby Battery Life on TPT2 - Page 2 - Lenovo Community

Driver download:
- broadcomm bluetooth driver 12.0.0.2200 - http://sdrv.ms/10lMlQl
- intel graphics 9.14.3.1087 - http://sdrv.ms/Zcryj0

A suggestion that will possibly save your tablet's battery from irreversible physical damade due to crappy OS sleep/wake/juice management
Go to control panel, power options, whatever plan you're using - change plan settings, change advanced power settings, here - in batery, low battery level 20%, low battery action - hibernate, critical battery level 15%, critical battery action - shutdown.

You should not allow you battery to be either completel discharged or completely charged, it causes physical damage to the electrodes of li-ion/li-poly (the same thing) batteries. Just stay somewhere in between and do not allow the charge to go very low or very high, and it will hold bigger capacity for longer time.

This is in case you think you solved sleep/wake/power drain issues, but your tablet can still wake at night all by itself cause of some app/driver/service/whatever, and it will pop in and out of sleep the whole night, doing some stupid tasks, consuming battery power so as to give you a morning surprise of 1% on the battery and believe me, you don't want to see this happen to you.

FURTHER SUGGESTIONS ON DIAGNOSING POWER DRAIN ISSUES

- Task manager CPU stats. Wipe these stats, reboot the computer, not use it but let is go right into connected standby, leave it for a few hours and see what's showing in task manager or even better - sysinternals process explorer (task manager on steroids). It can be not very conclusive though. The problem with this, this method can be only partially efficient at finding issues caused not by apps/services, but rather by drivers.

- Event Viewer - any power/wireless connectivity/cpu related logs from the period your device was in connected standby. Just filter by source and time.

- DISABLING SERVICES - IMPORTANT - sometimes, even if you disable a service in services.msc (task manager 'services' tab>open services), it can REMAIN active. Google Update is an example. I disabled its activation tasks in Task Scheduler, disabled it in services.msc AND STILL there's one thing you need to do - run>msconfig, here 'services' tab, filter by all non-microsoft and preferably disable most non-microsoft here. There's also googleupdate here... On my Smart PC 500T I left Intel thermal framework, SamsungConfiguration, SW-Update and TabletServiceISD.

- I also suggest, if you can, try disabling wireless connectivity for sleeping. If it's an issue with the wireless driver it might not solve your problem, but it might decrease it (and the broadcomm wireless driver found on clovertrail devices apparently is the cause of many connected standby issues..).

WHAT HELPED ME PARTIALLY BUT SIGNIFICANTLY IMPROVE POWER DRAIN DURING CONNECTED STANDBY
Here's the link to the topic that largely helped me since yesterday (power logs look much better now, still not perfect though):
http://forum.tabletpcreview.com/sams...tml#post324003 - older Intel DPTF drivers from acer and Lenovo Wifi driver instead of broadcomm's (links to driver files within this reference). A driver issue after all.... intel....

Also there's a guy here that did the same and it helped him too to a large (but uncomplete) extent - http://forum.tabletpcreview.com/sams...tml#post326789

///update, three days later
Turns out I might have just got incredibly lucky with my initial power logs. I've observed my ativ 500T's behaviour a little bit more both in case of sleeping with nothing up and running and all wireless connectivity off on airplane mode, I still getsome 20-30% battery drain during the night. Same goes for the case with a with few apps left unclosed before sleeping - chrome, 2 pdf files, desktop onenote..

Which brings me to conclusion I've still got a big insanely irritating problem. ]]> Windows 8 citizen-x http://forum.tabletpcreview.com/windows-8/56912-sleep-wake-connected-standby-battery-drain-issues-possible-solutions.html A Little Levity... http://forum.tabletpcreview.com/windows-8/56784-little-levity.html Thu, 09 May 2013 23:44:06 GMT ...Courtesy of WinSuperSite: I liked commercial # 1: http://winsupersite.com/windows-8/craziest-windows-8-ads-ever-made ...Courtesy of WinSuperSite:

Hi guys,

I hope you will be able to help me a bit.
I have Samsung Ativ PC Pro with 4 Gb of memory.
initially all was fine bur recently i started getting low memo error even with very few apps running. like 3-4 chrome windows or simmilar.
when i check stuff in task manager i see that even at fresh restart i have like 2,5 GB of memory ocupied but at program listings (processes) there is hardly anything more then 0,5 GB, just usuall stuff with google drive being largest at about 40 Mb...
just below the image of memo occupation (2,9 out of 3,9 ocupied) i have some numbers:
memory in use 1,4, available 1,3, commited 14,7/15.9 cached 1,4 GB
speed 1600
slots used 1/4
form factor SODIMM
hardware reserved 115 Mb
paged pool 246 not paged pool 335

any idea what I can do to check the resaons? and what can be done with it?
