HP had lots of issues in the past with faulty power Jack. If you are inclined, you can also removed the motherboard and test the fuses to see if one is blown ( use a multimeter to see if there is one that does not allow power to pass thru). Otherwise you will need a new motherboard. It might also be the power button module that is not working or the cable that goes from your power button to your motherboard is either loose or disconnected. Let's go back to your motherboard if you plug in your laptop and the battery light does not come on even if battery is inserted, then the problem is with the motherboard.
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 the 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.
are there any lights on the laptop when its plugged in like the charging light , does the power ***** have a light on it that turns on if neither of those turn on then its hyour power adapter thats it. if they do turn on msg me back
1. Check the adapter
2. Check the processor
3. Check the motherboard if defective replace new one.
Note: You need to know the right spare part number of your motherboard e.i 443776-001. Here's a sample video
Yes, you can take the laptop apart and resolder the jack to the motherboard. I've never done it, but have read articles about it and watched a video on youtube about it. Go here and you will find a fast video about it, which will give you an idea about what you have to do (it's a fast motion video). There will be other videos to refer to, also. I couldn't find one for the xz148, specifically, but there are some for the Pavillion series. Sounds like you've identified the problem, the task now is to get it apart to get at the power jack solder points. Take pictures as you take it apart, to help you with any problems reassembling it. Good luck!
Test your voltage on your power supply...There should be a voltage amount on the sticker on your power supply telling the output.Make sure yours is putting out the right amount.If this test good,your probally looking at a bad dc jack.Jacks need to be checked by a certified repair person.....Goodluck......If this is helpful ...Be so kind as to give a testimonial.....Thank you
The BIOS battery is on your motherboard. It looks like a watch battery. Easy to identify and remove. The power jack, while you have your case open look to see if your jack you are talking about is souldered to your motherboard or is a card. Let me know.
