HP Pavilion g6 laptop not powering up

[o_ahmad]

Hi all.

I have a HP pavilion g6 laptop which won't power up, and I think the problem is with the laptop. I tried pressing the power button without the battery and adapter in it for 15-60 seconds, but no luck. Using the battery without the adapter was likewise unsuccessful. I noticed the AC adapter worked with another laptop, so the adapter is fine. The light next to where the adapter plugs into no longer displays like it used to, so I think something is wrong with the motherboard. If one of the capacitors, integrated circuits or dioides has blown, could that stop a laptop from turning on? Also, does this specific laptop have a fuse inside, near the power jack? If so, could this be the cause? If not, what else inside the motherboard may possibly be the cause? Or could a faulty powerboard possibly stop a laptop from powering up?

Thanks!

Hey there! @o_ahmad, Thanks for stopping by the HP Support Forums!

I understand you have issues powering on your laptop.

Don't worry I'd like to help you out.

Did you make any hardware or software changes on your PC?

Have you tried checking with a different battery or adapter?

Please provide the product number of your laptop to assist you better.

Check if the pin inside the DC (Charging) port is bent or broken.

Try plugging the adapter into a different wall outlet and check if it helps.

Please try the steps recommended below.

To perform a power reset on a laptop with a removable battery, use the following steps:
Turn off the computer.
Remove the computer from any port replicator or docking station.
Disconnect all external connected peripheral devices such as USB storage devices, external displays, and printers.
Unplug the AC adapter from the computer.
Remove the battery from the battery compartment.
With the battery and power cord unplugged, press and hold the Power button for about 15 seconds to drain any residual electrical charge from the capacitors.
Insert the battery and plug the AC adapter back into the laptop, but do not connect any of the peripheral devices.
Press the Power button to turn on the computer.
If a startup menu opens, use the arrow keys to select Start Windows Normally, and then press the Enter key.
After Windows opens, reconnect each peripheral device that was disconnected, one device at a time, until all devices are reconnected.
Your laptop has been reset. After a power reset, it is a good idea to run Windows Update and HP Support Assistant to update all device drivers. 

Also, refer this article to further troubleshoot no power issues with your laptop.

If the issue still persists after trying out the steps. It is a hardware issue with your laptop.

Please contact HP support for service options.

Hope to hear from you soon!

Have a great day! 🙂

Thank you MrRobot for your reply!My product ID is:QC170EA#ABU. The model is: g6-1196sa.

Could you confirm the laptop has a motherboard fuse as asked before, to ascertain whether or not to rule it out as a possible cause, please?

I already tried plugging the adapter into a different wall outlet and power reset, but to no avail. The problem is not with the charger or battery, as the charger worked with a different laptop and the battery won't power it on, hence the laptop must be the issue.

I made no hardware or software change before it became inoperable. When my laptop was last working, I put it on hiberate and don't recall if I switched it off from the mains just before it officially went into hibernate or afterwards. If before, I'm not sure how this would cause something in the laptop to be affected.

The pin in the charger is fine which is expected, given that as aforementioned, the charger works in a different laptop. I have posted some photos of the power jack port and it seems fine to me.

If the power jack in the laptop was faulty, I don't think this would stop the battery from powering it on. Since my battery has no effect, can you confirm a broken power jack would not preclude the battery from switching it on?

Tried the article advice already but no luck. I noticed there a very silent sound from the AC adapter when plugging it into the laptop. Whenever attempting to power on the laptop, the sound changes in pitch until I release the button. Does this indicate something significant for troubleshooting purposes, namely, that the power jack is working, so the issue is probably the motherboard?

If the motherboard is an issue, how much on average do you think it would cost to fix a faulty fuse, capacitor, integrated circuit, MOSFET chip, dioide, etc? Also, for which of those motherboard items would the repairer likely need to purchase from HP if replacing any of them? That would give me a sense of how expensive it would be to repair, to determine whether or not it is worth doing so or buying a new PC. I live in the UK.

Thanks a lot!

@o_ahmad, Thanks for your quick response and time.

I appreciate your efforts for getting back to us.

As you mentioned you needed to know if your laptop has motherboard fuse.

I'm not sure what do you mean by motherboard fuse.

However, I have found maintenance and service guide for your laptop. Which instructs you to replace the system board.

You can refer the service guide to know more information.

Note: Refer page 73 for more information.

If the solution provided worked for you, please mark accepted solution for this post.

Hope this helps!

Have a great day ahead! 🙂

Hi,

Some laptop motherboards have a fuse near the power jack. Could you ask a more technical colleague to read my previous post and answer my questions, please? Then, I will be able to identify what item in the motherboard needs replacing which would be cheaper than merely replacing the entire thing (assuming the issue is with the motherboard, not power jack).

@o_ahmad, It's great to hear from you again.

I appreciate your efforts for trying out the steps.

As HP does not replace the components on a system board and we replace the whole system board if it is faulty.

I would suggest you contact HP authorized service provider get assistance.

Have a great day ahead!

Take Care! 🙂

Hi,

I did say in an earlier post that I plan on going to a shop to replace the faulty item in the motherboard, rather than the entire thing as I do not want and cannot afford to do that. I will ask someone else capable of answering my queries.

@o_ahmad, Thanks for getting back to us.

As I mentioned in the previous thread that since we don't replace any components on the system board.

However, I did some research and found the replacement part you are looking for.

The part you are looking for is called Power connector. Please find the part number listed below.

Power connector (includes cable) 641137-001

You can order the part from HP store using this link.

Hope this answers your query!

Have a great day ahead! 🙂
