Windows 7 launched last  October has shown the public that Microsoft can still create something different to its predecessors.  As it is today windows 7 has 6 different flavors being

1. Windows 7 Starter
2. Windows 7 Home Basic
3. Windows 7 Home Premium
4. Windows 7 Professional
5. Windows 7 Enterprise
6. Windows 7 Ultimate

As usual Microsoft managed to package all the different flavors for home users, the small business and medium to large professionals.

By the first looks, windows 7 looks pretty much like Windows Vista, however with many new features over Vista and the much appreciated better memory handling and less memory hungry Operating system.  Although there are six different versions of the Operating system it is common that new users choose between Home Premium and the professional versions.

Windows 7 starter lacks the media center facility and the most famous Aero which striclty speaking makes the system a little bit more sexy.  The windows 7 Ultimate versions, is mostly for that technical guy who wants more from his PC.  Most computer retail shops today will simply choose between the home Basic and the professional so for the home user there is not much choice than to either get what there is available or else choose to buy it off online which is more complex for the basic home user.

Windows 7 professional has all the media and entertainment facilities just like the home premium however it has added features for business users too.

Windows 7 enterprise is for a large enterprise or businesses that would buy an OS licenses in bulk.   It has all that window 7  Professional does, but with some other added features like BitLocker and a direct access capability, so you don’t have go through a VPN for a simple remote access connection.

Windows 7 Ultimate is, as the name implies, the full ultimate version of Windows 7. Unlike Vista, where it was the combo of Home and Business with a couple added features, this time, it’s like the end user version of Enterprise. The Enterprise version is that version of windows that now regular people can buy. It has BitLocker, and a few other advanced features.

The fault manifested only after [...]]]> This Laptop Was reported to have the screen faint after a specific amount of time. Although this is usually associated directly with the screen itself I decided to have a better look inside prior to giving the final verdict to the issue.

The fault manifested only after a certain amount of time so the following tests were performed to verify the symptoms.

1. Powered on with power supply and left idle for a certain amount of time where the fault did not manifest.
2. The next test was to run several tests like opening multiple programs and changing from one program to another like running streaming on Microsoft Media player and browsing a heavy website. Still the screen did not fade away at all.
3. Ran De fragmentation and other heavy tasks to warm up the system.
4. After several tries and a long time after the Laptop was on the fault started to display the symptoms by slowly fading away.
5. Turned off and left to cool down.
6. Turned the laptop back on but this time in safe mode and ran similar tests and the same problem was noticed so the problem is surely with the hardware.
7. Turned on batteries and the problem took longer to manifest since the laptop takes more time to heat up when running on batteries.
8. The next process was to dismantle the laptop and have a better look at the board.

Disassembly procedure.

The first task was to remove all the possible periferals like the hard drive, the ram, the cd rom and keyboard off the way as these are usually clip on stuff that can be remove easily.
THe nect step was to disconnect the screen from the board and unplug the wireless antenna then remove the screen all the way off.

After Doing so the bottom screws were removed and the upper chassis could be clipped off.

Screwed off the mboard screws and remove the board from the lower chassis of the laptop.

On inspecting the board there seemed to be no problems with the video connector and no problems with the pinouts. I looked at the connector with a good lens and this is highly advised since most soldering issues cannot be easily detected especially on these types of boards.

Nothing seemed to be bad with this board so I decided that it must be the screen.
