Hello Armyboy941
May be there is improper grounding with the power outlet where you are plugging your laptop. Did you try using a different power outlet at a different place (may be at your friend's house or any other premises)?
If the static noise is still audible, you can try the following:
Step 1 - Assuming that you are using Windows 7, right-click the speaker icon from the System Tray (at the bottom-right corner).
Step 2 - From the context menu, click
Recording devices.
Step 3 - On the
Recording tab of the
Sound box, click to select the icon representing the microphone that you are currently using.
Step 4 - Click the
Properties button from the bottom-right corner of the box.
Step 5 - On the microphone properties box, go to the
Levels tab.
Step 6 - Reduce the
Microphone Boost slider bar to minimum.
Step 7 - Go to the
Enhancements tab if it is available. (In some cases, you may not see the
Enhancement tab and in such situations you can skip directly to
Step 9.)
Step 8 - Check the
Immediate mode checkbox and then check all the checkboxes in the list.
Step 9 - Now go to the
Advanced tab.
Step 10 - Ensure that both the checkboxes in the
Exclusive Mode section are checked. If not, check them manually.
Step 11 - Here you may need to select each option from the drop-down list individually one at a time, click
Apply to check the result, and pick the best option that resolves the problem.
Step 11 - Finally click
OK from the bottom of the box.
If the above solutions fail to work, you can borrow a charger from any of your friends or colleagues and check if it is the charger that is faulty.
If everything fails, it seems it is time when your laptop should be diagnosed by the professionals at an authorized service center.
Good Luck!!
