The RAM may need reseating or it maybe faulty.
If reseating the RAM module/s doesn't work and if you have two RAM modules, then try one at a time.
You could take the RAM to your friendly shop and get them tested or test them in another laptop.

My aceraspire4330 wont power on


you can try the power system check by doing the following:

To verify the symptom of the problem, power on the computer using each of the following power sources:
1. Remove the battery pack.
2. Connect the power adapter and check that power is supplied.
3. Disconnect the power adapter and install the charged battery pack; then check that power is supplied by
the battery pack.

If you suspect a power problem, see the appropriate power supply check in the following list:
"Check the Power Adapter"
"Check the Battery Pack"

Check the Power Adapter
Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power
adapter cable. See the following figure
1. If the voltage is not correct, replace the power adapter.
2. If the voltage is within the range, do the following:
* Replace the System board.
* If the voltage is not correct, go to the next step.
NOTE: An audible noise from the power adapter does not always indicate a defect.
3. If the power-on indicator does not light up, check the power cord of the power adapter for correct
continuity and installation.
4. If the operational charge does not work, see "Check the Battery Pack"

Pin 1: +19 to +20.5V (Centre pin)
Pin 2: 0V, Ground (Shielding / Surround)


Check the Battery Pack
To check the battery pack, do the following:
From Software:
1. Check out the Power Management in control Panel
2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct.
3. Repeat the steps 1 and 2, for both battery and adapter.
4. This helps you identify first the problem is on recharging or discharging.

From Hardware:
1. Power off the computer.
2. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground).
(Terminal 1 is closest to the edge, Terminal 6 is closest to centre)
3. If the voltage is still less than 7.5 Vdc after recharging, replace the battery.

To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. If the battery status indicator does not light up, remove the battery pack and let it return to room temperature.

Re-install the battery pack.
If the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light up, replace the DC/DC charger board.

Some people have successfully reset the charging system with the following procedure:

  1. Shut down the computer
  2. Close the lid
  3. Unplug the AC adapter
  4. Remove the battery
  5. Plug in the AC adapter
  6. Open the lid and turn on the computer
  7. Log in to your user account as usual
  8. Shut down the computer again, and close the lid
  9. Unplug the AC adapter
  10. Put the battery back in
  11. Plug in the AC adapter, open the computer and start up again
The battery should now charge normally. If this process needs to be repeated any time soon, the small clock and parameter backup battery inside may have gone bad. I don't know where that is in this particular model. In some designs, it's accessible from the wireless card or memory compartment; in others it's somewhere under the keyboard.

Charging failure can be the result of a broken cable in AC adapter, often caused by yanking on the cable to unplug it rather than pulling on the plug body. Sometimes the adapter jack gets worn out or the solder connection inside the laptop breaks. In these cases, usually no light comes on when you plug in the adapter or the AC power indicator light is intermittent.

Also, if you have a Sanyo battery pack there are some issues with the battery management firmware. Gateway has a BIOS update to address the problem.

Your battery pack is not charging. By removing the battery pack and trying to run on AC only you have proved the AC adapter is either not working or the power is not getting through to the laptop.
The best way to sort this is to try another adapter and see if the laptop works, if it does then your adapter is broken (this is possible even though it reads 19.1 under no load.)
If the laptop still does not work with another adapter then the laptop itself will heed repair.

Computer runs off battery only not the power cord (battery is brand new)


You have a serious problem with the power and charging circuit. Normally if the battery is faulty the laptop can function with the power adapter plugged and running off the mains.
If a techo cannot fix without replacing the motherboard, then replacing the motherboard might not be a cost effective solution.

You salvage the hard drive by inserting it into an USB hard drive adapter case and use it as an external USB hard drive.
Sorry about this, you have very few options.
