Hi, Simply can't get these things..
go to jaycar or any electronics bit retailer and get a female plug suitable for your AC adapter and attach/solder it to the mainboard with a 2 - 3 inch long cable or longer (2 wires). polarity is very important - can't afford to make a mistake.
Leave that female adapter loose & flexible at the back of your notebook, that way you won't break it again.
You are not he only one, Stats = 20% of notebooks die this way.
I am a techy and I see then every day..
I have done many of them, this way..
Hope you can do it too.

My laptop is not switching it just lights up the battery led when i put in the adapter.and it produces some sound where you connect the adapter


Remove main battery and try again, if no! sub out the ram memory one at a time and test each, if nothing! remove the hard drive and power up, remove CD/DVD drive and finally the wireless card, if none of these work! the motherboard has major issues.

Hi my x58 won't start up, the light on the power adaptor just flashes when I connect the laptop to the power mains, please help


Hello.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Power off and remove the battery. If the laptop powers on with just the adapter connected, your battery is faulty.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

Hi i need help plz, i've my laptop do not power when i plug the ac adapter ther' is no ligth


You may have a DC connector problem:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

Acer 2480 2247 won't power up -no lights no nothing, pwr supply is not the problem,lid close switch isn't stuck ,pwr. on switch seems fine and power supply jack on motherboard is not broken


Remove the main battery and the power supply, allow several minutes to get rid of any residual charge, now plug the power supply adapter back in and press power "leave battery out" is there any change? if not! remove power supply, now! press and hold power for 60 seconds to reset the laptop. Next install main battery back in and the power supply adapter, power up! if no change, the motherboard is the problem.

Will not power up


FirewallAvat: Your problem is likely because your battery is dead and the adapter isn't charging it. This may be due to broken connections in the cable from the adapter. Flexing often causes the wire inside to break near the plug. Generic replacement adapters are available, or the wire can be cut back a bit and a suitable replacement soldered on. The cause might also be broken solder connections on the main board at the power jack, This is common from stress due to the power plug flexing. It is usually possible to open the computer and resolder these connections, although sometimes there's too much damage from arcing before the connection fails entirely.

DocBrown: Does the power LED on your computer come on when you connect the adapter? If not, try the adapter in another outlet anyway. Sometimes one outlet in a strip can go bad. Check the output of the adapter with a voltmeter. If it's bad, replace it or try repairing it as noted above. If the adapter is good but the light isn't on, you might have the bad power jack as well.

Check on the motherboard if there is a fuse. It may look like a diode or resistor.
Does it work on battery, if you have a charged one?
