My notebook wont turn on and i noticed the power light isnt turning on either. It was working fine last night but wouldnt turn on this morning. Any help is appreciated. Thanks in advance.
How old is your battery? It may need replacing. If the battery is fairly new, I would try: Making sure that the charging cord is secure in the laptop, outlet, and the adapter box in middle of the cord.Plugging the laptop into a different outlet.Trying a different charging cord for the laptop. 4. Replacing the DC connector port where the charging cord plugs into the laptop.
Hi, Use a Voltmeter to check that there is 19.5V DC on the output plug of the charger to prove that is supplying the power to the laptop. If the charger is OK then you need to open the laptop and check that the DC-In jack is OK and that there is continuity through the jack to the motherboard. Sometimes the centre pin of the connector breaks internally. They cannot be repaired, they have to be replaced. Here’s the maintenance and service guide for the laptop, taken from this webpage. Go to p.89 to view the necessary pre-requisite steps and then the procedure to remove the power connector cable. You initially don’t have to remove it, just disconnect the power connector cable plug from the motherboard and then use an Ohmmeter to test the wires for continuity between the jack and the cable plug. If the jack is faulty, the spare part number is 719859-001. Search online using the part number only in the search term of your browser, to find suppliers of the part that suit you best.
The first and easiest thing to try is the power adapter. Does it have a light on it, and if so is it shining? Ask around and see if you can find someone with a similar HP. If it has a plug which fits your laptop it should be compatible. Take the battery out of yours and try it with their adapter. If still no joy then it’s not going to be easy. I take it there’s no spash screen, or even a faint glimmer from the screen when you press the power button. And the power button hasn’t lost its click or feels any different to usual. That would indicate there’s a fault in the circuitry close to the power inlet. If you can disassemble it, (see this disassembly guide - marked as Diffficult, but it really isn’t) look very carefully for any signs of overheating or burning in that area of the motherboard. If so, take some close-up photos of the area and post another question
