Re: power supply problem

You can get from the manufacturer, however many retailers carry universal power cords, ie radioshack, best buy, circuit city. To get just an end to splice on to your existing cord that would be from the manufacturer as those are proprietary. Just a word of warning if you are going to replace the cord you're lookin at about 80 bucks for a universal, as laptops use odd voltages at high amperage. Bring it in to retailer or bring the model number so it can be matched up properly. Good luck, hope this helps.

It's possible that the power supply is broken, which moves power from the battery/power cord to the rest of the computer. This requires soldering to repair. However, there are a number of things which could be wrong with the computer, almost all of which will require a technician to repair.

The laptop might still be under warranty, if you don't have that choice then you need to go to a computer repair store where they can sub your power supply with a universal one to find out which problem you have, and they may not even charge you, but this is a quick sure fire method and you can decide which way to go.

Seems more like a problem with the power receptacle where you plug the power cord into the laptop.In order to fix this problem, you will need to disassemble the unit to get access to the motherboard & replace the power receptacle with a good one.

Power wont come on

Either the power supply has a loose connection or is faulty.
You can try removing the battery pack, press and hold power button for 3 seconds and then put battery back in and see if it corrects the problem. You can test power output from the supply to see if it is putting out the voltage it states it should on the label of supply.

I have an acer aspire 5570z and it wont power on, at all the. battery is fine and the charger is fine i have tested both any help is much appreciated

Hello there:
This could be the result of a couple of different things
The power connector where you plug your power into the computer could have a piece that is broken in there
or you could have a bad power converter on the board it'self that could be bad
and you might even have a bad power supply in the computer
First i would remove the power cord and battery and press in the power key to discharge anyesd that may be stored and hold it in for 10 to 20 seconds andthen connect the power cord and see if any lights come on
showing that you are getting power if not i would start troubleshooting the connector piece for the power cord but if their is power showing now try to start the computer if all is good than you should be able to turn it off again and reinstall the battery and try it again but if still nothing than you will have to troubleshoot the motherboard or the power suply ok If you have a warranty on this you may consider using it
I hope that this is very helpful for you
best regards Michael

Power cord

You can buy a power plug and solder it to the wires. You need to be careful so that the polarity of the plug is correct for the laptop, if you reverse the wires you can damage the laptop. If you are not sure, get a computer service techo to do the fix.

The pin that the power cord goes into has broken off

Is the cord broken in the computer, or the monitor or the pin broken and stuck in the machine? If it is in a desktop it goes into the power supply. Which you can change the whole power supply fairly cheap. that is if it in a desk top computer. 4 screws, 4 or 5 connectors and ta da new power supply, All you need is readings off power supply such as wattage. Good luck

Possible mishap with the power?

Three possible reasons why this has happened
1 - The power supply cord has a faulty or broken wire somewhere and needs repairing. Take a good look and see if you notice anything out of the ordinary (UNPLUG THE POWER CABLE FROM SOCKET AND COMPUTER BEFORE ATTEMPTING TO LOOK)
2 - There could be a physical problem with the plug or socket for where it connects to your laptop and needs to repaired or replaced
3 - The computer has short circuited with the power cable socket in your laptop preventing any power for the Laptop

Hope this helps
