Tried with a new charger but it made no difference. Moving on to connector...

PS: the charger you linked to is 65W, but looking at specs for my laptop (and on my original charger), I got a 45W. Was your suggestion on purpose?

That is actually what the marketing information shows as compatible with your notebook. I will provide a link to the partsurfer information for your notebook if it is available and I have not already done so.

edit: Partsurfer does not show a listing for your notebook.

It will help with faster charging as well.

Hi,

So I finally received a replacement power connector and went through with the replacement. Unfortunately, I am afraid it's had absolutely no impact... The laptop is still not turning on, while the LED next to the power connector still blinks 3 times (white) went trying to turn the laptop on.

So I am back to scare zero in terms of figuring out what the hell is wrong with that laptop which was otherwise functioning perfectly fine...

Any other suggestions?

Many thanks

I found an HP document that decodes the beep/blink codes. Unfortunately, three blinks indicates a hardware failure.

That does not necessarily mean it is the system board.

Replacing the internal battery would the next logical step.

That isn't a terribly difficult task and is still not such an expensive part.

I will edit this and find UK prices on new battery for you. The replacement battery general price is about £40.00

Use the remove/replace video link that I provided earlier.

Hi,

Thanks for the continued support and help 🙂

If it's a battery failure, wouldn't the laptop work when I tried to run it plugged in, without the battery?

Thanks

(PS: haven't tried that after changing the power connector, I guess that's one more thing I can test)

Yes. It should.

That will let you know that the charging circuit on the system board and the power adapter is OK as well.

Performing hard reset would also be a good thing to try.

I tried running the laptop without a battery (just plugged in) before and it had no effect (except the LED wasn't even blinking IIRC). I will try and again with the new power connector and report in case it's a weird combo of the two.

Hard reset I've tried a hundred times already with no results unfortunately

Please don't confuse the DC power connector with the power adapter, which you like to call a charger. The DC power connector is where the power adapter's connector plugs into the notebook.

Take a close look where it plugs into the notebook to see if the pin is broken.

Watch the video labeled Power Connector adapter to see what I am referring to. R & R videos link below

No confusion here, I changed both the power connector and the power adapter (which I sometimes call charger indeed ).

I have now tried running the laptop (with new adapter and connector) plugged in with and without the battery inside. In both cases the laptop doesn't turn on, but without the battery the LED next to the connector doesn't show any sign of life.

erico · ‎09-19-2018

OK.

If the connector has not failed, it means that the system board is the most likely candidate for the failure.

I would check it if I were in your position because that is the last inexpensive troubleshooting step.

If the DC connector has been checked with a multimeter and shows continuity where it should, then it is not the problem.

Since the power/charge LED does not light up when a power adapter is plugged in that isolates the problem down to the charge/power circuit

Ok, could I get your help figuring out which system board I should buy? I am scared of getting the wrong one.

When you say "Since the power/charge LED does not light up when a power adapter is plugged in that isolates the problem down to the charge/power circuit" I am not sure I follow. The LED does blink when I try to turn the laptop on with both the power adapter and the battery plugged in. If I remove the battery but keep the power adapter, then nothing happens. Was that clear from my previous message?

I am still very confused how all of these issues could have started simply from the laptop running out of juice. In your experience is this something that can cause the types of failures we are testing for?
