Samsung Magician + RAPID Mode + 840 EVO SSD = can't sleep

[jrichrds]

When I have Samsung Magician installed and RAPID mode enabled, after putting my PC into S3 sleep, it will wake up from sleep within a minute. This is with my 120GB Samsung 840 EVO and Win7 x64. I have "allow this device to wake the computer" unchecked for all devices, but the problem goes away after uninstalling Samsung Magician.

Anyone else experiencing this?

What is the reason of the wake up? Type this into Command Prompt after the wake up:

powercfg -lastwake

I had a similar issue with the Magician (and it appeared to be widespread) and I solved it by removing it from the startup items (i.e. only run it when you want to).

More interesting is why Samsung do this……

Just remove Samsung magician from the "startup" folder. I had to do the same.

More than likely it is due to having Magician optimize the OS for high performance, not allowing the SSD's to ever sleep.

Under the advanced tab in the power set up, you will notice it says 'allow hdd's to sleep = never'...

If you don't have Magician running, then Windows will let you manually sleep. Magician however does not know the difference between 'away' sleep and manual 'shutdown' sleep.

That is my hypothesis anyway.

Does RAPID mode still work with Magician removed from the Startup folder?

And is RAPID mode even worth using? The reviews I've seen on it seem to indicate it does a good job of caching.

Rapid mode still runs even though magician does not. It just lets you enable or disable rapid mode. I've just confirmed that SamsungRapidSvc is running on my computer, and magician is not.

RAPID mode depends on what you do. I tried it and it doesn't make a difference for day to day use, so I disabled it, since I read a review where the benchmarks were up and down...

Thats true. Magician is long time known to not let you use S3. I don't know why. Just remove it from autostart.

ok thanks. I wasn't sure whether it was RAPID mode that was causing not being able to sleep, or the Magician software independent of the RAPID mode.

By the way, I couldn't quite understand the wording within OS Optimization -> Advanced of the Magician software for "Prefetch/SuperFetch." I'm recalling off of the top of my head right now, but the description is something along the lines of "Disables features the SSD does not need." So if you set that to "enabled" does that mean you're enabling the Magician software to disable it? Or does "enabled" mean Prefetch/Superfetch is enabled.

Looking in the registry, I saw no difference either way...prefetch and superfetch remained enabled. But maybe I was looking at the wrong setting.

My problem was waking from sleep. It wouldn't wake up every time. I could hear my fans power up, but no video. So, I stopped Magician from running, and it would wake up just fine. I also put the swap file to 0 on the SSD, and set it to my HDD (this IS good to do). But, I had contacted Samsung support about the sleep issue. This is their reply:


Dear Customer, thank you for contacting Samsung Support regarding your concerns and inquiries. We apologize for any inconvenience this may be causing you.




We have an AMD APU (CPUs are not the current high performance standard) in our newest test machine with all the newest windows drivers installed, latest firmware for BIOS and Chipset, and the latest SATA driver.an 840 Evo is running this machine's OS and we have no problems here.


Please note that you are not supposed to put a computer with an SSD to sleep and this is what is causing the issue. It creates a read and write on the SSD, which will degrade its performance and length of use of the drive.\


Thank you again for contacting Samsung Support and have a good day.

That's baloney. What kind of lurking SSD bugs are they trying to hide, claiming that you shouldn't sleep (or do they mean hibernate?) your SSD? I've had no trouble to date doing just that with my notebooks. One running an OCZ Vertex Plus R2, the other running an 80GB X25-M G2.
