No power,adaptor light on when i connected to laptop the light flash and off

Take out the battery and start up using the mains connection. If it doesn't startup the problem may well be your mains adaptor.

Sounds like your power cord is no good.

the laptop will work with just adaptor plugged in and the battery removed

however your issue could be an issue the adaptor causing the battery to discharge as there is no charge getting to the laptops battery or it could be an internal issue with the motherboard

try just the adaptor if that works then replace the battery

hoping this will work

1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
4. The motherboard could be defective & needs to be replaced.

Just check the power connection from the AC going to your laptop if the power adaptor of your laptop are working. Note; you only know that the power adaptor was working if the LED (Light Emiting Diode) was light because the power adaptor are have the LED to see it that they are working normally. If the power adaptor working normally their was a problem of the power supply inside your laptop and need to be repair by the electronic service center. But if the power adaptor are not working the problem are in the power adaptor. I recommend that you replace your power adaptor and bring it to the computer store to check its type and model it is because only same type or model of that power adaptor to be replace.

Your battery might be completely drained. Remove your battery and and plug your laptop directly to the power outlet using just your laptop's AC Adaptor. If should now work with the battery being bypassed.

If it won't work in this way (connecting to AC Power with the battery removed), there must be something wrong with your laptop's board.

thanks for using fixya!!

Please do and observe the following:

1. Uninstall the battery pack.
2. Then, connect the AC adapter, we will try to use the power coming from the AC, then turn on your laptop.
3. Observe what will happen.
4. If still doesn't work, install again the battery, then connect the AC adapter, check if its going to work.
5. If not, perhaps you have a problem neither with the battery or the AC adapter.

I suggest that you bring your laptop to a service center. Good luck!

pls rate me positively! thanks!

Sounds like the power jack is damaged or faulty.

Sir,
you remove your Laptop main battery and adaptor for aprox 10 min then fix again battery and adaptor then on power button m/c is on.

Bad DC IN (probably after last repair)
One side of the DC Jack is not getting ground connection.

This happens when one of the negative leads are not connected. Simple fix for skilled tech
