Computer Printer Repair

Problem:
Processor: Intel Celeron C900
Operating System: Windows 7 Home Premium
I have an advent roma 1000 laptop, I have had it for over a year and occasionally had problems such as this, last time I found a solution on the internet but I have not been able to find it since, it was something to do with going into control panel and power settings, but I can't remember. Every time I press the shutdown button in the start menu, nothing happens, every time I press the power button on the laptop itself nothing happens. I have changed power settings so that my laptop shuts down when I close it but when I close it and open it again nothing has changed. Please help!

Solution:
Windows 7 laptop wont shut down issue could either be Software or Hardware related. Boot into Safe Mode and check if you can shut down properly.
Boot your computer in Safe mode.
If a problem doesn't reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes.
Perform a hardware clean boot to determine if any hardware is posing this problem.
1. Go to start and type device manager.
2. Select device manager from the Control Panel list.
3. Right Click on Sound Card, Video Adapter, and Network Adapter one by one and click disable.
4. Reboot the computer. If the problem is fixed then you can enable the hardware devices one by one to find the exact device that caused the problem.
After you found the device that is causing the problem, installing the device’s latest driver should fix it unless it’s a hardware issue.
