If you do not see lights on the laptop when you turn it on,

  • it may be the power pack, as once the battery is flat it will not boot.
  • some power packs have a light on when they are being use, have it check .
if the power pack is ok, and you see nothing on the screen when you try to boot up, then it is not posting.
  • (power on self test) so its a hardware problem. try the following :
  • remove the memory from the back of the laptop,and if you have more than one stick ,swap them around as you may have a bad one,
  • you will have to remove one or more screws to do that.
  • also make sure the battery is seated correctly and you have the power cord connected and turned on.
  • if you only have one stick of ram,and can't beg borrow or steel one from your mates, take ram to your local pc shop and ask them to check it for you.
  • if the ram is ok return to that shop with laptop to have them check it out for you.
  • as it could be many things that has caused this problem.
good luck

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.

Says plugged in not charging


Take out the battery and make sure you can turn on the laptop with just the AC Adaptor hooked up.

If you can then you know the AC Adaptor is good. Try another known good working battery in the laptop, if the battery charges then you know that the old battery is bad.

If the laptop doesn't charge with a know working battery or a new one then you know that the motherboard is bad.

Compaq presario a900 model a931nr wont boot, help!!!?


Sounds like the battery is in trouble (discharged) or the charger is bad. If you have access to a voltmeter, read the voltage across the power cable plug with the pack plugged into the house outlet socket. Does a lamp work when plugged into the same socket? If the pack checks ok, then the battery may not be able to receive charge. Have it checked by a dealer.
