Looking for Answers about samsung (Unknown)?

Yes. You can upgrade RAM of this machine to 8GB(4GB+$GB). 6GB (4GB+2GB) is the default configuration. Just remove one screw beside memory on the back and replace 2GB with 4GB.
Also i am not sure if warrenty of the machine will be void if you upgrade RAM.

The maximum RAM recognized by the BIOS is 8 GB. So if you have 6 GB installed, you can access the memory card from the bottom of the notebook, take out the existing 2 GB and put in the new 4 GB DDR3 memory.

Yes, the RAM in the 7 Series notebooks can be upgraded up to 8GB. The unit comes with either 8GB or 6GB installed. If you have the unit with 6GB you can upgrade it to 8GB by removing the plate on the bottom and installing it from there.
Note: You only have access to one (1) of the RAM slots without physically opening the case- and opening the 7 series laptop can damage it even with professional tools.

The 15.6" Chronos Series 7 has a 2.2 GHz Intel Core i7 processor.

yep it was a bad production. Its on all of them just about. I tried out 3 and all had same problem

Yes unfortunately this laptop seems to have space bar loose for this keyboard.
Also its very hard to replace keyboard on this machine.

I have upgraded mine to Win7 Ultimate by entering a new key in Computer>>Properties; I really didn't want to reformat the HDD and reinstall every single driver.
Anyway, so far everything is working fine.

I advice you not to install W7 ultimate. It needs more ressources than the home premium version, but the uprade of the software not really improves the features you can use. W7 ultimate needs 64-bits drivers. today developers work generally with 32bits drivers. I other words, you can upgrade but it will not improve the performance and many drivers are in 32bits.

It's normal, it is because of the Wifi light up indicator. The same thing happens with the Caps Lock key, it will remain lit when the backlight is turned off to indicate if Caps Lock is on.

Use Fn key+F9 key to decrease or reduce the brightness of the backlit keyboard
Use Fn key+F10 key to increase the brightness of the backlit keyboard.

Also the keyboard automatically adjusts to the surrounding ambient light.

Yes apparently the USA units did not ship with a sticker and serial number at the bottom of the unit. That is not a problem as long as you registered with the correct serial number for your unit.

We also looked on the accessories page for your product and found a VGA-to-mini HDMI adapter available for purchase, but the model number does not match the one you provided.

That is a configurable setting. Goto the Easy Manager and turn off the "Battery Life Extender". When turned on, the maximum battery charge level will be at 80%. When off, it will charge to 100%.

Check if you have a VGA ouput if you do then just plug it in

Thank you for contacting Samsung.

The screen will always dim slightly when AC power is removed. We recommend you check the Power Settings in Control Panel. The brightness setting may be set to Samsung Optimized and you can change this a setting more to your liking.
