The 2012 Samsung Series 9 13.3" (NP900X3B)

[shelleyevans]

Thx. I will try to do the same over the next several days and see what happens here, too. Usually I don't think about it until the next morning.

well it's sata iii so if ours does support it it will be twice as fast. will report back

Twice as fast as what? I guarantee it isn't going to be twice as fast as my machine. The mSATA in my NP900X3B is SATA III 6 Gb/s Samsung and nearly as fast as the 256GB 7mm Samsung Series 830 drive I have.

[Thors.Hammer]

what speeds are folks getting on the 830?

Here are a couple of tests

right i didnt know it was sata iii stock - samsung folks told me it was ii when i asked them.

even if runcore is faster it would be marginal. not worth the effort - going to return it.

Several reasons. First, I don't want to give up any disk space for a hibernation partition. Second, I don't really want to use hibernation.

When I use sleep/resume, it's during a busy day of meetings and I am bouncing between conference rooms. Sleep/resume is convenient but I don't usually leave a lot of applications active so saving and persisting state isn't an issue for me.

I'll do some testing with sleep and the loss of battery over the next few evenings and see how my machine does. I usually shut it down at night, but I'll suspend it instead and see what happens.

Yes, IRST indeed wastes space, but to me that is the only real downside. IRST actually first goes into the normal sleep mode. It stays in that mode for 75 min. Only after 75 min, it will go into this special hibernate mode. It is not the traditional slow hibernate mode in Windows where it takes 10-20 sec to boot up with logo and everything, it is super fast, less than 5 sec (you probably think it was sleeping). So, you are going from about 2 sec to 5 sec (sleep to IRST hibernate). During that time, you don't waste any battery if you left it in your bag over the weekend or what not. That said, if you shut down, then it won't waste battery either.

I left my S9 untouched for a week and it work up within a few seconds. The battery had dropped from 80% to 76%.

Thanks for this explanation. That rapid resume is one of the S9's useful features. We just need bigger SSDs so the extra space is not an issue but using one of the sparse partitions is still a nuisance. I guess that it uses mapping between RAM and SSD and needs to avoid the risk of a file being moved.

Putting 8GB RAM on board will, I presume, increase this SSD space loss. At the moment my S9 also had the standard windows hiberfil.sys. Running Powercfg -H Off to disable it gives a message "The system firmware does not support hibernation". So I manually zapped it and restarted. It didn't automatically reappear.

First of all, thank you. I LOVE this board-- every problem leads me to more understanding (eventually).

Second of all: ARGH. The more I understand, the more I want to get this feature to work. I know it's the IRST service that won't let me sleep at all, have reproduced the behavior multiple times now. I have even reproduced the behavior in safe mode, so I know it's not my start up programs. I have removed and reinstalled the service several times. I have deleted and recreated the partition. I changed ACHI from "Auto" to "Manual/Enabled" in the bios. Can't think of anything else to do, short of a clean reinstall.

Does anyone know how to ensure that the WiFi stays off when turning the laptop on/off (and indeed when it turns on after sleep mode)?

If I use the Easy Settings, they are not remembered once the machine turns back on....

Do you reckon that your machine was in hibernation or sleep?
Sounds like very little battery usage if it was just sleep (looking at the way mine performs)?

Kind regards,

Mine seems to remember the last setting if sleeping but it doesn't remember the WiFi setting when the computer is restarted. What is even worse is that it turns Bluetooth back on, which I don't like since BT can be a power hog. So if you are flying, you have to use only sleep and not restart the machine. I think we need to all hit Samsung with bug reports.

The workaround is the untidy one: Disable the WiFi and BT devices in Device Manager.

I think it had hibernated but using the Intel rapid system it was up and running in very few seconds.

Yup, I had to disable the BT in Dev Mgr too (although easy settings will still let me turn it on/off - doh!).

How do you guys play the hibernate / sleep options wrt using the lid / pwr button?

I can't quite decide if I'm better off having the laptop go into hibernate every time I close the lid or have to remember to press the power button if I want it to hibernate!

Is there really much of a difference between hibernate & sleep start up times?

Kind regards,

Nic
