So after gettting my replacement R7 (with the wifi issue fixed) I opened it up to upgrade the RAM.   The 2Gb chip inside this new R7 is the exact same type of Kingston chip that was in my old one (detailed previously) -- same specs and all.  So if the wifi issue was related to the RAM as was previously suggested by somebody, it does not appear to be the chip itself.

After replaceing the chip with the 8Gb crucial one I ordered, the system booted up and recognized it right away.   No need to go into BIOS or anything like that.

Hi TwelveTone,

Can you tell me in detail what exactly was your wifi issue?  Thanks in advance.

I just wanted to add that I just checked this with Acer via the Chat option.  They also confirmed 1333 MHz, PC3-12800.

Thank you to all posters in this thread. To build on what you have taught me, I made a picture teardown thread:

Just want to Reply to help with sleep problem most times since Win 7 - 8, I've found a resolution to sleep Problem. >> Look under Device Manager >> Tools >> Hidden >>  { go to property on all keyboard, Mouse, Displays, and All 'UBS Componants' Look for under } >> Look on Power Management Tab make sure Allow the computer to turn off...' Is un-check'd

Gave the USB Hub uncheck Suspend fix a go, didn't work. Exact same behavior still crashes ~30 seconds after turning back on from Sleep. Sleep has never once worked on my R7.

Woundering is there a Power Management under the OB SSD Chip? Under the Events what is it showing for reason of crash?

[b9chris]

There's not much to go on. In Control Panel > Administrative Tools > Computer Management, Event Viewer > Windows Logs > System, there are no errors leading up to the crash - then 2 errors on the next boot, one saying the system crashed with no other info, the other saying

volmgr

Crash dump initialization failed!

Don't know if it's related but it is suspicious that the most common log entry there is this:

UserModePowerService

Process C:\Program Files\Acer\Acer Power Management\ePowerTray.exe (process ID:9588) reset policy scheme from {381b4222-f694-41f0-9685-ff5bb260df2e} to {381b4222-f694-41f0-9685-ff5bb260df2e}

This seems to occur multiple times per hour every day while the machine is on - didn't even realize this process was running. Wonder if the machine would do better without it... .

1. First have you try to reinstall Acer Power Management - "Acer Power Management \ ePowerTray.exe"
2. Look those numbers up under Registery - {381b4222-f694-41f0-9685-ff5bb260df2e} < should be Windows 7 Power Plans  Same for other Reg. # < These are same the same numbers on all computers depending on OS Ver.
3. Also try looking at ePowerTray.exe with Process Exporer - "By Microsoft" Point to the .Exe file rec. put to sleep then wake and check log of what it's doing with in your system.
4. Here are some CMD effort if you want to get all crazy on it Hahaha. We all know how sleep mode is like windows biggest bug....       http://technet.microsoft.com/en-us/library/hh875530.aspx < But if you decide to look here you might see the problem with the logs
5. One last Resort is write a logon script Powercfg.exe logon script to configure power management settings. But this can be a pain 

And I forgot about this Power Option

I'm not sure much of that makes any sense, sounds like a lot of stabbing in the dark.

Killing ePowerTray didn't help.
