freezing while waking up from sleepmode

Hi guys!

About a month ago, I purchased a Sager NP8255, installed Win 7 x64, and all the drivers. Shortly afterwards, I noticed that when the laptop wakes up from sleepmode, it sometimes freezes on the waking up screen (the screen with the Win logo), sometimes at the beginning of the animation, sometime a little bit into it. At that point, it no longer responds to any keys and I can only long-press the power button to get anywhere. If I tell it to remove the cache and boot from scratch, it boots easily; if i tell it to try and wake up again, there is a chance that it wakes up alright, and there is a chance that it will freeze again. The same thing happens with hibernation. It's worth noting that after a fresh bootup, if i put it to sleep, it wakes up fine.
I read somewhere that there might be a problem with the video drivers, so I re-installed those. I duno what else to do and am wondering if you guys could recommend something.

 

Since it doesn't right after booting, then the core system seems fine. So keep note of which programs you run, and try them one at a time, and try to sleep during and after each one. See if one of these programs, or a driver is causing it. So test sleep one by one with the software you use.

 

how would i go about testing each driver?

 

You test drivers by using them. I.e. boot the computer, put it to sleep, wake it up, now test the sound driver by playing some sound, put the computer to sleep, wake it up, play a game, sleep, wake, etc, etc. Same for software.

When you think you have it, verify it by itself. Some problems only show up in pairs. I.e. X is fine by itself, so is Y, but do X and Y, then you have a problem.

Good luck.

 

How much ram do you have and what form is it in? Eg 4x4gb for 16gb.

 

I havent had much time to test it, but I have 2x4 gb with all the 'recommended' software that came with the drivers, most of it is usually occupied. I thought that Ram might be the problem, but I ran stress tests on it, and no errors were found.

 

Testing can take some time. I like to do it in batches. I.e. I think the problem might be one of these, so I run those and test sleep. If it fails you know it is one of those, or vice versa. You said you have no problems without the cache? Are you talking about a SSD cache, as sleep doesn't use a cache? If so you may be missing some of the Intel drivers, or they need a update, or...

 

I mean all the information it saves when it enters the sleep mode/hibernation. Basically, after a failed wake-up attempt, it gives me an option to try again, or do a fresh boot.

 

ok, so a quick update.
I tried hibernating (not sleeping) with some everyday programs open (chrome, word, steam, etc) and could not wake up. when it asked me whether I wanted to try again, I said yes, and it booted up fine... so, not exatly sure what this means..

 

allright, another update.

i put it to sleep while playing a movie, music, even having Civ 5 open. woke up immediately with no problems. I think it woks fine because i woke it up right after putting in to sleep. It never even went to the 'resuming windows' (if it did, it did it for a split second).
My OS is installed on an mSATA ssd. I remember reading somewhere that it could be a power glitch with the ssd, but the problem outlined there was not exatly the same as mine..
could it be that? and how would I fix it?

 

Just keep in mind that sleep mode and hibernation are different. Troubleshooting is different for the two of them. SSDs can cause issues with hibernation caches sometimes. But that would not be an issue with sleep mode.

Seems like it has been running for a while now without issue. Just keep track of what is running before you put it in sleep mode. Hopefully a pattern will show up. It could be a program, or memory, or something else. Being able to duplicate it is a good start.

 

to be honest, i've kind of given up.. I've been keeping my laptop on most of the time and only seldom shutting it down (no sleep mode or hibernation)

 

Alright! New developments!
So after I've given up trying to pinpoint the problem, I just started leaving the laptop on for the night.
Recently, I started simply shutting it down and I noticed that it has exactly the same problem on regular startup!
So, if its cold (not been on in a while) it gets stuck on the 'starting windows' screen, eventually giving me BSOD. If I power it down and power it back up again, it boots like a charm.
So it seems like a hardware problem. just wondering if people encountered this at any point

 

In the past, 2 things gave me this issue on separate occasions. A nvidia driver. And a synaptics SMBus Driver.
If you know it's the Nvidia driver, then ask the mods on the forum to work on it for you and give them your hardware IDs (they have a thread for it about verde support for specific notebooks). If you know it's the synaptics driver, then try an old version.

 

Do you have an Intel 530 SSD? What hardware do you have, and what have you added, internal and external?
