If it is part of the plug side that goes into the wall then it is not worth fixing. You can replace this pretty easy. On the front or back it will tell you what the input and output voltage are as well as the amperage. It will be 120v input and most likely a 12v output. Could be less like a 9 or 6 but that is the number you need to match. You will also need to match the amperage as well. It will most likely be in the milliamps. There are many universal adaptors that would work for you available at Walmart, Target, Best Buy etc....

Male power port is loose hard to chasrge unit


The port is female with a center pin, the male portion is on the charger.
If you damaged this pin and it is loose you will need to replace the plug on the charger. Since these are very similar to some laptop charging ports, having a broken laptop around with same size charging port would be a bonus, or a friend with one too, but they are relatively cheap, I fix broken ones on laptops several times a year and can find a pair of them shipped for under $10 typically.
Sometimes you need to solder them on, sometimes they connect with a dongle, should be easy enough to take apart and peek inside.
Other wise, if that is beyond your expertise, does the charger have a cigarette lighter, you could likely charge it through that port, or with a trickle charger directly on the battery cables on the unit if need be.

OW TO GET MY ACET ASPRE ONE IT STOP BLACK SCHREEN NO POWER


Step by step troubleshooting.
Verify power outlet is good
Verify power adapter is good
verify connection to computer is good
fully charge battery
test
=======do this
Check power source, plug known good light into AC receptical.
If AC cord has connector to power block verify it is properly seated.
plug adapter into AC outlet
Verify Power is present at power connector with another similar computer or voltmeter. (12V to 20V)
When plugged into computer, charge (not power) indicator MUST light either red, amber, or green. If not, connector on computer may be broken.
leave overnight or until charge light is green
turn on normally.

most likely causes:
- loose connector
- broken wire from power adapter
- broken power plug on computer.
- anything else is probably beyond ur capabilities to fix.

Blue light on ac adapter no lights on the Eee nothing when pushing the power button


Check the voltage on the power output of the adapter.
Even if it's right, it could be failing under load, but then the LED usually goes out.
Try running the unit with the battery removed, but my real guess is that the power input jack has come unsoldered.
Move the power input in small circles and see if there is a position where the charge light comes on in the Eee.
If that happens, you need to resolder the power connector on the motherboard.
If not, I would strip the unit to the motherboard and check the pico-fuses and SMT mosfets around the power input area.
If that is beyond the scope of your abilities, I would go to www.SuperTech-IT.com and schedule a repair for the unit.

My screen went out on my 50'' nak ...how much to replace it


If your diagnosis is correct and you have a broken plasma screen unit then it's beyond economic repair as a new panel costs more to supply and fit than buying a complete replacement tv.

If the tv has simply gone into protection mode due to a failed cooling fan or if a transformer, relay or circuit board has failed then it's normally a straightforward and cost effective repair but definitely not a DIY job. Fans and relays are the cheapest repairs, typically labour for one hour plus the (usually) cheap parts, transformers and circuit boards are typically one to two hours labour but the parts can be very expensive but the total repair is typically far less than the cost of another 50" plasma tv.

NOT CHARGING CANT TURN ON


The modern adaptors are 'switched mode' that allows them to accept a wide range of input voltages (typically 100-240 VAC). Unfortunately, they have some components in them that are critical to their operation and on these, many mfrs. like to cheat on quality. This causes the early demise of the supply.
I saw Acer supplies offered at <$20 US searching on Google so I suggest you replace the supply. Note; this may not fix your problem anyhow as most laptops have a bit of circuitry inside to control the input from the pack and choose whether to use the battery or not. If that fails, the unit may not receive input from either.

absoloutly not!!!!! if the pin has broken in the external power cord and not inside the PC itself then all you have to do is replace the PSU ( power supply unit ) and the lead, this should cost you no more than £35 and its easy to replace yourself

Battery charging


When you initially used the unit was it with the battery or not? If it was with the battery was the AC hooked up also? You need to remove the batteries from the equation to find the problem. Hook the camcorder directly to the AC unit and see what it does. Also you do not mention how you know that the AC unit has power at the lead. Checking with a DMM does not garantee it. I have seen units which have the correct voltage until you put a load on the AC adapter. At this point the AC adapter could be bad, the battery could have a memory or be bad or the input jack could have a bad solder joint. If you have a DMM and know how to use it check the AC adapter for proper output. If it checks OK you will have to assume that it does not have the problem I mentioned. I have only seen that one time. With no battery on the camcorder, plug the AC adapter in and try the unit. If it does not work you probably have a broken input jack. If you are good with tools, have jewelers screwdrivers, magnifying glasses, a steady hand and lots of patience remove the covers to expose the jack and repair the connection. This should solve your problem. If you are not capable of the repair you will need to find a good reputable repair facility to take care of this. Cost should be less than $100 US. Good luck.
