I have Dell Inspiron N5110 which cannot shut down neither in Windows 7 nor in Ubuntu Linux. I specifically booted Ubuntu Live from the CD to eliminate the possibility that the problem is in the Windows 7. Shutdown in Ubuntu does not work either. This proves that the reason in not a BACKGROUND application in Windows that remains hanging and does not allow the laptop to shut down.
The laptop cannot wake up after Sleep or Hibernate either.
I have tried every solution that you advised to all the other people in the forum that have the same issue.
1. The laptop cannot shut down in Safe Mode either.
2. It cannot shut down even after Clean Boot Mode - all non-MS services disabled and all Startups disabled.
3. I tried changing the Advanced Power Options of "Allow Hybrid Sleep" - both ON for "On AC Power" and "Running on battery" - no change.
4. I tried installing the latest video drivers for Nvidia. This did not help either.
5. Running only on battery does not change anything - still cannot shutdown.
6. Running only on AC adapter without battery - still cannot shutdown.
7. I tried removing the AC adapter and battery and holding the POWER button for 30 seconds to RESET the laptop - did not work.
ATTENTION: I've been reading your forums all day and saw at least 10-15 reports of the same problem and not a single fixed case.
8. This is why I have not tried Flashing the BIOS to the latest version - I read other people tried that and it didn't work either.
9. I loaded BIOS default settings (F9) - still cannot shutdown.
REMARK: Changing something in the BIOS and trying to Exit once caused the laptop to freeze and I had to Power Off by holding the button for longer.
10. I ran DELL Diagnostics from Boot menu (F12 at startup) - no errors found.
11. I could not locate IEEE 1394 Adapter in Device Manager to change its Power Management settings.
Actually none of the suggestions you may give for changing something in Windows makes sense because I already mentioned that shut down in Ubuntu does not work either.
The issue seems to be either in the BIOS or a hardware problem. But which component? Is it the CD/DVD drive?
This is a new laptop.
Please advice how to proceed. If you know which component fails please tell me.
Solved! Go to Solution.
Remove the keyboard and palm rest (guide from dell shows you how) and you should see a small coin cell battery. Remove it for at least 10 seconds, then put it back in. Enter BIOS and make sure there isn't anything weird that was changed. It should work properly now. I have had this working in Ubuntu 12.04 for the last few days, with no problems.
THIS IS THE FIRST REAL ANSWER THAT COULD HELP ALL OF YOU FOLKS !!!!
I HAVE NOT TRIED IT. I JUST RETURNED THE LAPTOP TO THE SERVICE AND THEY FIXED IT SOMEHOW.
MAY BE THEY DID THE SAME AS ADAM_SQL WROTE !!!!
....OR MAY BE THEY CHANGED THE FAULTY COMPONENT.
Anyway thanks a million ADAM.
IMPORTANT!!! : HOWEVER DOING THIS BY YOURSELF MAY CANCEL YOUR WARRANTY SO YOU BETTER PRINT THIS ANSWER AND TAKE THE LAPTOP TO THE SERVICE WITH THE PRINTED PAPER.
After spending days fixing my friend's laptop having this problem, i arrived to a conclusion that the wireless is messing up with the sleep thingy.. whenever you connect to a wireless network and then close the lid, it does not turn on again.. but if you do not connect to any networks, you can put your laptop to sleep with no problem at all..
BUT THE FIX TO THIS PROBLEM IS: go to control panel, go to add and remove. you will have installed more than one driver for the wireless.. Proset wireless I assume.. please delete all others except the bluetooth one.. When you would be uninstalling the intel proset wireless wifi software, the uninstallation may hang for a while.. no need to worry, just restart your laptop normally from the start menu, when it restarts, your problem will be fixed
This problem is related to hardware, as it is present in more than one operating system. The issue was present in Windows 7 and Ubuntu Linux 12.04. It is a hardware problem relating to CMOS. Removing the CMOS battery will fix the issue in the long run. It has been confirmed in several places.
Well then you probably have a different problem, because Linux was having the same issue. If the same issue is present with 2 very different forms of software, there is a hardware issue. Doing a fix in Windows will have absolutely no effect with Linux.
My laptop would not sleep/shut down in Win 7 or Linux. the fan was not working in Win 7 or Linux, and it took longer than normal to POST. My fix has solved all three of my issues and I haven't had a problem since on either OS. (Besides Windows being a garbage OS in the first place)
Not saying that your solution is wrong, it just seems that there is a different issue between our devices.
thank you so much for helping your follow poor Dell customers. Your solution (opening up the laptop and removing the batterie) worked for me.
I tried so much, next would have been reinstalling windows, that would habe been at least half a day useless work on top.
Dear Dell "customer service"
how comes it is so hard to find the solution to this problem? How comes you seem not to even have confirmed this problem?
It´s your customers who spend hours and hours trying all this useless stuff that you find first when you search for the solution in the web.
Please take this serious, offer a patch or at least publish an easy to find webpage where the error and the solution is named.
