Question about HP ProBook 4730s Notebook
Hello.The most common reasons for power issues are the battery, power jack and power adapter/cord.Power off and remove the battery. If the laptop powers on with just your hp probook 4730s adapter connected, your battery is faulty.If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.If no change, the power adapter is probably faulty and needs replacement.Hope this helps.

If you have tested the power adaptor with a multi-meter to confirm it is OK or the other adaptor is also OK assuming that it is the correct voltage and at least the same current rating. Then the fault is most likely the power connector in the laptop.
To confirm this, power up as normal with the power adaptor connected and switched on, when the blue LED dims wriggle the power connector where it connects into the laptop and if the LED comes on or blinks, that means that you have a faulty power connector, it couls be a dry solder joint at the power connector.
It is possible that the power adaptor is shutting down (thermal overload) due to insufficient current capacity, Check the Amp rating of the laptop, it is usually on the lable on the botom of the laptop and check it against the power adaptor, the adaptor should be equal too or greater that the laptop's current rating.
To fix a faulty connector, you can dismantle the laptop and with a fine tip temperature controlled soldering iron, resolder the power connector and hopefully this will fix your prolem.
