20 Most Recent ASUS AC Adapter- Universal Notebook AC Power Adapter (NBACA407D2) Power Supply Questions & Answers

I've seen this issue on an HP computer before. For some odd reason, some models decided to use "cost efficient" housing around the AC power unit on the inside of the laptop housing. If you know how to replace it yourself, I would recommend just acquiring the piece and replacing it on your own. There are some sellers on eBay who do provide quality products which are assembled with the highest standards.

You have to check with a volt meter.

You need a replacement AC adapter, it's very cheap online.
1)Output Voltage is within +/- 5% of your old charger's output.
2) Output Current is the same or higher than that of your old charger.
3) Connector tip must fit securely into your laptop.

First check the wall socket make sure you are getting power, plug a lamp into it for instance. If there is no green light on the adapter then it is bad and you will need to order a new one from your computer manufactor.

Super cost-effective Universal ASUS AC Adapter with 1 year warranty sell in famed and old battery power charger store.

hi,

you can try to conect the laptop directly to the power outlet without using the battery just to verify if it the battery or the charger itself..If it still power up the laptop,that means that the adapter is still working,if not,well obviously,its the battery itself


thanks

1. the adapter may be ok but the unit battery that the adapter is charging may have a bad cell and not taking the charge or the power connector may need replacement .
Only a qualified tech can determine this by doing electrical checks with a meter and or diagnostic instrument.
Take your unit to a tech to do a diagnostic.
More than likely it is the battery.

Only a few things come to mind:

1. The plug on the MB is defective
Solution: Have the plug on the motherboard replaced

2. The universal power adapter is defective
Solution: Buy an ASUS power adapter and test it out. If it doesn't work, return it. If it does, then get rid of the universal adapter.

Good luck

Look for a program called Sound Booster or one called DFX. DFX is my favorite because it not only boosts the volume, but lets you add other effects to enhance you sound as well. There is a free version. but to get all the effects you have to upgrade to the paid. If audio is important to you, check it out.

Try going into sound select and test reinstall driver off Asus website..if you installed new windows or update drivers may not work right...see if you can roll back driver in device manager ..if not lookup your laptop model and reinstall...
