    Yea, having the same problem. Searched everywhere... no result.

    Doesn't turn on with the battery, with battery + power, power - battery...

    Some even recommended putting it in the fridge, which I did. Still nothing.

My IBM T20 won't start up, i tried to place the AC adapter but it is not charging. when I pressed the turn on button, not even a light is flashing. what should I do.


Whenyou connect the power adapter into the laptop, does the power LED light up? Ifnot then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

Dell 9400 wont show AC power icon


If the computer is connected to an electrical outlet, the about10.jpg light operates as follows:
  • Solid green: The battery is charging.

  • Flashing green: The battery is almost fully charged.

If the computer is running on a battery, the about41.jpg light operates as follows:
  • Off: The battery is adequately charged (or the computer is turned off).

  • Flashing orange: The battery charge is low.

  • Solid orange: The battery charge is critically low.
Looks like the AC adaptor is faulty.

Laptop Not booting - No Screen


Clean your memory card, or reseat it. Clean the edge connector with soft eraser if reseating doesn't solve it. Do this when battery is disconnected, completely turn off and no other power supply is connected to it. If not maybe ram failed already. This is the first step before going to anything. For additional instructions try to find it in youtube. Post us some update.tnx

When I plug in my ac adapter into my computer to charge it the green light turns off and won't charge my computer


The diagnostic procedures from the Dell User Guide are as follows:

Total Power Failure When Using a Battery
If an AC adapter is not connected to your computer, the computer's power source
is a battery. If the battery indicator flashes amber or is a steady amber, the
battery needs to be charged. If the battery is flashing green and amber, the
battery may be defective. To troubleshoot this problem, use the following
procedure.
1. Turn off the computer and peripherals, and disconnect them from AC power.
2. Reseat each installed battery by removing it and then replacing it.
3. Turn on the computer. Does the green power indicator light up?
Allow one minute for the computer to initialize its components before checking
for signs of power.
Yes. Continue to step 4.
No. Use the AC adapter to connect your computer to AC power. If the computer
operates normally when using AC power, go to step 7. If the computer does not
boot when using the AC adapter, see the previous subsection, "Total Power
Failure When Using the AC Adapter."
4. Does the battery indicator flash amber or show a a steady amber light?
Yes. The battery needs to be charged. Go step 5.
No. Go to step 7.
5. Connect the computer to AC power, and fully charge the battery.
For instructions, see the topic titled "Charging the Battery" in the online
System User's Guide.
6. As the battery charges, does the green battery indicator light up?
Yes. Go to step 9.
No. Go to step 7.
7. Is the battery indicator flashing green and amber?
Yes. Your computer may be in a hot environment. Charging the battery in this
condition may affect the life span of the battery. Continue to step 8.
No. The problem is resolved.
8. Disconnect the computer from AC power. Is the the battery indicator still
flashing amber?
Yes. You may have a defective battery. Continue to step 9.
No. The problem is resolved.
9. Remove the battery, and press its test button. Is the uppermost indicator in
the charge gauge of the battery flashing?
Yes. You have a defective battery. Continue to step 9.
No. The problem is resolved.
10. If a spare battery is available, fully charge it, and then install it in the
computer.
11. Turn on the computer. Is the power indicator off?
Yes. Your original battery is defective


good luck
