Nicole; check the alternator belt, loose,worn, is it still there and on.
If battery is new and connections are good, and belt is good, probably a bad alternator. Alternator cost $125 to $200, labor $60-$120

Simple as pie... you will see the harddrive mounted horizontally in a small shelf after you tae the cover off. You have to unscrew the philips screws that hold it in the shelf and unplug the connectors. make sure you label the wires so you know which ones came from that harddrive... they is usually room for 2 harddrives and two complete sets of connectors, don't mix them up. (One is the master and the other called a slave.) There is an adapter for the harddrive that you should always keep should you need to replace the harddrive, (comes in two pieces on either side) the new ones don't come with the adapters to fit them in the case; they are bare bones. If you don't want to go through the gymnastics of taking the other tower apart and installing the 2nd harddrive in it to read it... an internal HDD adapter can be purchased from Tiger Direct for a nominal cost. I allows you plug you internal HDD into a USB socket in any PC (desktop or laptop) and read it as you would a Flashdrive.
once in the setup (F2 at boot) turn on Caps Lock, NumLock and Scroll Lock (all 3 keyboard lights on)
Press ALT + E (system should beep once)
Press ALT + F (System should beep once)
Press ALT + B (System should reboot and re-detect drives)
The harddrive is not working, or is not connected properly.
Shut the laptop down. Remove the battery. Turn the laptop upside down. Remove the screws in order to remove the harddrive cap. (The acer laptops have small signs on the caps. The cap that has the little circe-cylinder signs on it, should unlock the harddrive) Remove the screws keeping the harddrive in place. Remove the harddrive. Clean the connectors on both the harddrove as the motherboard. Reconnect the harddrive and turn the laptop on.
If it is working, turn it off, and fit all the screws in again.
If it is not working, then you probably have to change the harddrive. You could also connect the harddrive to another computer, to make sure if it is broken.
Please take this time to back up all your data. This could be a sign your Harddrive is failing if it is not your harddrive it could be a fan. You need a tech to look at your system right away to prevent failure. Fans are cheap to replace but if they fail you can lose your entire computer. If its your harddrive your looking at 2-3 hours labor and hardrive replacement. Generally it is worth doing.

its probably on its way out or damaged. I would make sure you backup all your important work and be prepared to get a new one. It may last for some time yet,but it is often a sign that there is some internal damage - best be safe and back up important work
You've done your homework on eliminating potential external sources so one of the few things left is a failed filter capacitor in the power supply of the unit.
'Hum' is one of the most common signs of this.
If a capacitor fails catastrophically, there are normally visible signs of it.
If you are adventurous, you can invade the subwoofer box where the supply and amplifier are probably situated and look at cylindrical parts in the area closest to the AC input.
The supply will be in whatever case to which the power cord is attached and the bigger box is the most likely candidate.
Capacitors of this kind can be in size from a 1/4 of an inch to 1 1/2" in diameter, have a plastic sleeve around them that is normally open at the top where the aluminum of the case is visible and they are mostly installed vertically in the board.
These often (but not always) have 3 scored lines radiating from the center.
Check around each of these for any signs of crusty deposits and on their tops, look for signs that the top has bulged.
If you find any looking like that, they are probably defective.
There are values on the sleeve that will be in 'uF' and voltages expressed in DC; i.e. one that bears 47uF/16VDC needs to be replaced with that same value.
If you make it that far, you will need only few tools but a decent soldering iron to remove the failed part and pay attention (marking is best) where the + and - leads go since they will fail and make a mess if improperly polarized.
If you do not see any with the signs of failure described, the only recourse is to find a tech with a capacitance meter necessary to find the failed part(s).
Since the cost of repair by any shop would exceed the replacement cost of a new set, you may end up contributing to a landfill.
