np530u3b very strange behavior

Hi
this is my situation:

SHUTDOWN_SUSPEND_HIBERNATE-when you give the command to shutdown,suspendor hibernate,computer stuck with power and wifi led on and heats a lot till the end of battery(or the forced shutdown with long press powerbutton/battery cutoff with pin)
REBOOT-when you give the command to restart,computer stuck with power and wifi led on for a lot of time and after that the computer shuts down
BIOS-exiting bios cause same behavior as "reboot"

-issue is OS independent,with win7 and linux you have the same behavior
-never enabled uefi
-removing additional memory stick doesn't make changes
-removing drive doesn't make changes
-I'cant figure when these problems began,probably????? after a bios update???????
-I tried downgrading all versions of bios and micom from 13xk to 09xk,but this doesn't seem to make useful changes,same behavior with all versions
-I tried to completely discharge battery.no changes



any ideas?
someone else with same problems?

 

I would look in Event Viewer > System Log to see if there's a record of what program is obstructing the shut down.

Also try booking in Safe Mode (press F8 just as Windows is starting to load) and see if you can then shut down.

Hi
I forgot to write before but nothing strange in SOs.No strange entries in events for windows,no strange entries in syslog for linux.on shutdown windows goes black like shutting down and stuck but nothing more and linux simply say that system halted and stuck.
Also,even without harddisk, if you go in bios and then exit you have to wait a long time and is for a complete shutdown .
pc doesn't reboot as it would do and stay off until you press the button...

Google has found this similar problem and solution: Disable Fast Boot in the BIOS.

Hi John
sometimes google provides misleading answers..sometimes we need to read better google answers..
I know that forum and I know very well that thread cause last post of two weeks ago is mine
and no,disable fastboot in bios is not the solution
That thread was from a user that had usb booting problems and the "solution" was for that problems,like wrote in the thread
You found it googling because the guy who gave the answer(and also me) also wrote in there that he has similar(maybe the same)problems like me:...strange behavior reboot,suspend,hibernate.....
but no one after that told about a solution,even the guy himself.
Guy that I try to contact without luck..

 

after hours and hours googling during the last weeks I can tell also that that post was the only "thing " found about "my"problem

there are a lot of posts about uefi,and about linux suspend problems,also posts about other OS related problems but only one (and now with this 2)related to suspend,hibernate,reboot,shutdown problem

 

The next step is to reinstall the factory image of Windows from the recovery partition (press F4 at the BIOS screen). It's a drastic step but one that Samsung Support (if you are still in warranty) would ask you to do. If that, once installed and without patches and updates, also shows the same problem then it's hardware. If the original factory image behaves correctly then it's a problem with software / drivers / viruses etc.

Thanks John but...as said before.... the issue is OS INDEPENDENT...strange bahavior also exiting bios without harddisk connected
so

may be hardware but also bios/micom related(but if I remember correctly micom is kb firmware..)
I read somewhere in some forum that one of the last bios update(for w8 compatibility)changes unexpectly some "hidden"bios settings and you have to manually activate-save-deactivate to rehave the correct situation but that was for other issue and also I think I tried every possible combination


mmm sounds like I have to go via samsung support..hopefully warranty is still valid...but I have to found time to spend for and I hope they are fast....

 

I think John is absolutely right: You should contact Samsung about this. Certainly if a factory restore doesn't solve it. If you say it's a problem across different operating systems, that only further indicates that it is a hardware and/or BIOS problem -- and reason to call them.

You've clearly tried many things already. I wouldn't spend another minute trying to debug this, other than that factory restore, then calling Samsung.

Edit: Again our posts cross each other

 

I don't deny that your troubles may have been caused by a BIOS update. Have you looked through this thread about the bricking problem? It might provide inspiration for some more attempted fixes.

And if you want to roll back the BIOS it is best to first go to the original one as described here and then upgrade to the version you want.

John

 

hey John
did you read me? I write in the first post that i downgrade bios from 13 to 8 passing all version in between..but thanks anyway
just for notice after that i upgrade to 13 passing newly all version in between
after I tried also mixing different version of bios and micom
Is possible to change everything but the strange behavior.....damn!!!

sure is not normal,maybe a hard fault,like some bad capacito on the board or....???
I agree I wouldn't spend one more minute to debug and try to solve this but....simply I'm a curious techman ehehehheheheh

I hope I will have my notebook back fully functional soon

have a good night

YO!!!

 

Thank you for your clarification. I read what you had written but it was unclear that you had first gone to the original BIOS or had succeeded in stepping backwards one version at a time.

It's useful to have everything set out clearly for the benefit of the next person trying to fix the same problem.

hi atreyu77,
I have the exact same problem as you have. At first I thought it was a linux problem (I am using ubuntu 12.04), then I tried other distros and it persistet... finally I booted up windows (I never booted it before since I purchased the machine, so I figure its as good as doing a recovery install) and had the same issues. No shutdown, no suspend. The machine just hangs with blank screen and fan running.

I found this thread after I was trying to upgrade vom 04xk (the original bios that came with purchasing) to 13xk, which seems to be the latest, but the update utility points to an invalid download url.

Did you solve it? Or did samsung support solved it? I'm a bit afraid as I read a lot of horror stories about computers beeing broken or ending up worse after a samsung support treatment. And since this issue is certainly annoying but the machine still works, I consider selling it on ebay instead...

Two things might have caused this, btw. First, I dropped the laptop from my bed while it was running and it switched off, but I could power up afterwards normally. Then, I added another 8GB module (it runs fine). Suspend was definately working after the two events I think, but I had issues like this from time to time and it became worse.

So, since one theory was a broken capacitor around here, this could be due to the dropped laptop or out-of-spec memory module (it gets very warm, and according to the specs only additional 4 GB are supported).

Ok, but long story short, how did you resolve this (if at all)?

regards,
Malte
