They try to power on the laptop with other power supply.
Now when you plug it's own charger you hear a noise from a delta electronic component with no sp0134-4r7, 0433w.?. The laptop does not power on or charge at all.
if you please can sent me the power schedule diagram for this model.
please reply to email@example.com

Try Resetting the CMOS on your Motherboard. Turn off the Laptop and unplug it Remove the battery undo the RAM cover Remove the RAM plug the laptop into the power Turn the PC on and listen for some beeping noises If you hear the beeping noises turn the laptop back off Unplug the charger Replace the RAM into the RAM slots Replace the the battery Plug in the laptop and power it up.
if you get video output, that's Great, if not, it's possible that you have a faulty screen
More than likely your power supply has failed. Your computer probably ran on the remaining battery power when you noticed it. If you have another power supply to try you could determine that. Also, the plug in on the computer takes a beating on laptops and that could have failed as well.
More than likely your battery is in good shape, it just hasnt been charging due to the poor charger.
try diconnecting the charger and holding down the power up button for longer, then try plugging in charger- turn on charger at wall then hold down power on button till power button on key lights up, i hope this helps you out ;)
Ok A few things to try 1.) Check the laptop on an external monitor, do you get a picture 2.) Is there power to the laptop from the battery and the charger? Try to see if the charger indicator lamp is blinking green rather than steady green 3.) Can you hear hard drive / fan noises and are there any lights on the laptop?
If the charger is blinking, indicates that power is not making the circuit, check tightness of charging port, if tight, assume fault on motherboard / blown main fuse
If picture on external monitor and not on laptop, assume backlight on screen dead or possibly the inverter
If no noises from HDD or Fan and No lights on laptop, then fault with motherboard
If you do get fan noises etc, but get BLINKING lights on laptop, assume possible fault with graphics chip, repost with details of blinking lights / colour and specific model of laptop
The problem might be the power supply charger that plugs into the laptop, unplug the charger and run the laptop on battery power, is the high pitch sound there when you power up? if this solves the problem, it is the power supply charger that is the cause.
OK unplug power supply from back of laptop, remove battery, insert power supply, if NO light, on laptop, power supply is broken..Replace. IF it is OK, hold power button ON for a while, or until, the PC starts, if/when it starts, shutdown, with power ON key, and then take out power supply, replace battery, replace power supply, turn laptop on, now should be OK.
Are you sure the charger is the correct specs for your model? Check the label on the laptop and on the charger to be sure they match. The voltage and amps should be the same. Most importantly check the polarity which will be a graphic that looks something like this:
What that is telling you is if the center of the plug is positive or negative. The only thing that matters is that the pictures are the same. If you switch your polarity you will almost always blow out your power supply on the system board. Does the laptop power on or has it not worked since you heard the noise?
If it has not powers on odds are the specs are wrong on your charger and you might have damaged the laptop. If the laptop still works then it is possible the charger is providing too much power or malfunctioning. A laptop will work with a more powerful charger sometimes, but it is never recommended as it will create more heat and reduce the life time of the laptop system board.
