DC Jack diagnosis:
1. Test power adapter for output voltage. Bend the power cable in various directions while doing this to be sure that there is no broken conductors in the cable.
2. If power adapter is Ok, connect it & see if the power LED on the laptop will glow when you jiggle the power connector in various directions. If yes, then the DC jack might be loose or damaged, & need to be either re-soldered or replaced.
3. If not, then disassemble the laptop. Remove any components that attach to the laptop's motherboard first (e.g. battery, hard drive, RAM, wireless card, optical drive, ... etc.)
4. Next, remove the keyboard & the LCD screen.
5. Finally, unscrew all screws that hold the upper cover & lower cover together so that you could gain access to the motherboard.
6. Inspect the solder points connecting the DC jack to the motherboard. Make sure that none of them is loose. If any, re-solder them.
7. Inspect the center pin in the DC jack. Make sure that it is not broken or loose. If it is, then you might need to replace the DC jack.
8. When you are done, re-assemble back the laptop.

My compaq won't turn on and nothing shows that the current is in but the adaptor works properly


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

My dell studio1555 laptop is not recognising my mains lead/charger


Plug the adapter into the wall outlet or power strip. If using a power strip, make sure the strip is on. Most laptop power adapters have a small LED light; the light will illuminate when power is being transferred from the outlet to the adapter. If the light illuminates, chances are you have sufficient power to supply your laptop. Wiggle the power cord if the LED light did not initially illuminate. If the light turns on and off when you wiggle it, you might have a loose cord in the adapter, or the outlet could be faulty. Plug the adapter into another power outlet, preferably a different circuit in another room, if the LED light did not illuminate the first time. If it lights up from the second outlet, the first outlet either does not work or other devices were using too much power on the initial circuit. Connect the other end of the adapter to the laptop and turn the laptop on. When the computer starts up, you should see an indication of how the laptop is being powered in the lower right-hand corner. If you see a battery icon, then the laptop is being powered by the battery, not the adapter. Make sure both ends of the adapter are securely connected. If they are, and if the LED light on the adapter is lit, then you likely have a faulty wire that is not properly connecting to your computer. If you see a plug or adapter icon, then the laptop is successfully being powered by the adapter. If the LED light on the adapter is not lit, then the bulb is out, but the adapter is still working.

Inspiron 1545-my AC adapter doesn't seem to charge my battery


Check the LED Your Dell Inspiron 1525 offers five small blue LED lights on the front left corner of the laptop that display the status of various areas of your machine. The middle light shows the charge status of the battery, with a solid light indicating charging. The light changes to a blinking sequence as it nears full charge and turns off when full. Without the adapter cord plugged in, the battery LED turns orange as the charge runs down. Check the color of the light to verify charging status.
Verify Connections and Power
Start with the simplest cause and work backwards to the laptop. Use a different electric device to check for electricity from the wall outlet. Verify that the connections of adapter cord are tight and secure at the wall outlet, the brick and the laptop. Check the adapter cord's brick for a small LED that lights to indicate the presence of electricity.
Check the Battery
Battery issues can prevent proper charging, ranging from something as simple as a mis-seated battery to as serious as a completely dead battery. If the adapter seems to be functioning properly, try removing the battery and checking the small metal contacts in the laptop. Clean any corrosion or dirt from them to ensure a solid connection. Reseat the battery so that it clicks securely into place. If in doubt, try purchasing a replacement battery and see if that works.
Check the Adapter
Unless you keep your adapter cord in one place and never move it, every day use of the cord can cause the wires inside the insulating material to fray and kink. This wears them down, and can cause short circuits. The circuitry within the brick can also short out, preventing the delivery of the proper amount of voltage to the 1525. Use a voltmeter to double check that the cord is supplying the correct number of volts to the Inspiron.
Inside Problems
Internal issues can prevent a battery from charging, such as short circuits and a broken adapter port. The adapter port, the small opening you plug the end of the adapter cord into, is attached to the motherboard to carry the electricity to the various internal electronics. If this component breaks loose from the motherboard, the electricity can't go anywhere. A repair shop can fix this, as well as diagnose any other short circuits, for you.

Cannot get my computer to turn on


remove all external peripherals. remove laptop battery. remove ac adapter.
plug ac adapter to wall power socket without the laptop connected check if the ac adapter led will stays on. if yes then connect it to the laptop and check if the ac adapter led turns off. if yes motherboard laptop has problems and need to be replaced.
if ac adapter led stays off without connecting laptop, try different wall power socket, if still ac adapter led is off then replace the ac adapter.
if ac adapter has light stays on then connected to laptop but laptop cannot even power up even the ac adapter led is on then laptop motherboard needs to be replace.

7. if ac adapter stayed on after connecting to laptop press now the power button on the laptop just once. check if the power led on laptop will turn on (check if power led stays on or it blinks amber)
8. if it blinks amber then remove all CRUs such as dvd drive, memory, hard drive and wireless cards. put them back one at a time. make sure you turn off laptop when putting removed hardware. this will check and isolate which causing the power led to blink.
9. if the power led stays on then turn it off again then wait a couple of seconds then press and hold on Fn key then press power button. wait for about 5 minutes while the power led is steady on, until you hear beeps once you hear beeps it means that LCD has problems. try then connecting laptop to an external monitor if it shows display there. press on Fn + F8 to toggle the display from LCD laptop to the ext monitor. if no display replace the motherboard. if it has display replace LCD.

Discharging Battery


hmmm..try to run it with battery out completely, just from the power cord.

also, does the battery have one of those surface charge indicators, with the sliding scale?

also, plug the unit in overnight, off, and see if the adapter will charge the battery.

sometimes, you get voltage, but no current, and when the computer/battery come on line, the load will drop the adapter.

does the adapter light stay on, when connected to computer?
