in the recording audio settings when the new line in device is plugged in select that as default, then it should revert back to old setting when it is not in use but select the default when you plug it in, however there should be an option in the audio settings to adjust the hissing you hear, see if you do not have some boost in the settings turned on, i know making the line in boost will create hiss
Hello. This is what I do every time my keyboard lights go off. Go to program. Click open Asus Utilities, Click open e-driver, which will let you down load all the drivers for your Asus computer. You should see a number of options you can pick to down load or pick ATK Package for keyboard lights. I usually down load everything in case there was an update for my drivers. Good luck: Daryl White
The memory compartment is on the bottom of the laptop in the middle.Asus does not offer a service document for this model, but memory is pretty standard. Touch metal before touching the memory.Remover the cover on the bottom so you can see the memory sticks. There are holding clips on both sides, now you just CAREFULLY spread the retaining clips and the memory will angle up so it can be pulled out, there should be another stick under the one, same thing and the other should come up.Now make sure you pay very close attention to the way it comes out and where the slot is on the bottom of the memory, you should set it down just as it came out, so you can put the new one's in the same way. Here is a common video of memory removal, watch this just to get a idea. It will make you feel more comfortable knowing.http://www.youtube.com/watch?v=D1oTz-F6xME
Computer does not boot up The problem maybe the RAM, it could be faulty or just needs reseating to make proper electrical contact. Reseat the RAM and then boot up your laptop. If it still does not boot up then remove the RAM module/s and take them to your friendly computer repair shop and get them to test the RAM for you. Just like you sometimes need a mechanic to repair your car, sometimes you do need a technician to diagnose and identify the fault or faults on your computer. Not only does a good service technican have the experience to deal with this type of problem, they also have the equipment that allows them to look at things the average computer user can't see, and he has a collection of replacement parts that can be used to quickly test individual components on your computer.
Have you done ANY updates recently? BIOS? Damage? Drop? Do you leave it plugged in all the time? Power Surge? Have you tried a System Restore/Recovery?
