HP ProBook won't turn on

[whoamomma2]

Hello everyone,

So i have a problem with my HP ProBook 4320s, it won't turn on. Here's whats happening when i try to turn it on. When i have the battery in without the recharger and i try to turn it on, the orange LED light for the recharger blinks 8 times and same when i have battery in with recharger plugged in. Note, the orange LED light should stay on when recharger is plugged in and it's recharging the laptop. Now, when i have the battery out and the recharge plugged. The orange LED light doesn't even turn on at all. 

Now here's what i have done. I did a hard reset, which i unplugged the recharger and removed the battery from the laptop. I then held down the power button for 60 seconds and after that i plugged in the recharger without the battery and attempted to turn on the laptop. Nothing happens and the oranged LED light doesn't turn on. I then left the recharger plugged in and this time inserted the battery. The laptop still won't turn on but the orange LED light blinks 8 times. Now i've tried this with 2 different recharger and same result above. I can confirm that the 2 recharger is working because the 2 recharger works with my other HP laptop, meaning it was able to recharge my other HP laptop.  My other HP laptop also shares the same recharger as the HP ProBook 4320s by the way. 

What i've also done is, i've opened the HP ProBook laptop, took out the RAM and reinserted the RAM and tried the above and same result. I did this because someone told me this could've solve my problem but it didn't.

I don't know what to do now to get this problem fixed. Can someome please help me?

Hey, it's me whoamomma2. Sorry i had to create another account, i kind of forget my password to that account and can't seem to recover the account. So i created another account.

Anyways, i've read the two documents you sent me. The second document didn't apply to me at all because it was for Windows 10 users and needed the laptop to be turned on to follow the guide. The first document didn't really helped or answered my specific problem. It did mention things that were relevant to my problem like Battery power LED off, and Caps Lock/Num Lock off means AC adapter not connected or failure. But that didn't answer my problem because i said my 2 AC adapter were working because i tried both of them on another HP laptop and both of them were working because they both supplied power and was recharging the other HP laptop.  But when i tried the 2 AC adapter to the HP ProBook without the battery, laptop still won't turn on and the Battery power LED isn't turning on either. I've already tried switching to another power outlet and tried it with a power surge board, but still the same result.

 Is there anything else you can do to help me?

Hi,

Thank you for the reply back and the feedback. Yes, the articles are somewhat general and include lots of information and at least half of it is not relevant but users only need to find their part.

Your issue seems hardware - e.g. the power stuff/power button does not give power to the device OR the motherboard could be dead. I'm afraid this can't be diagnosed remotely as the machine is not powering up and is remote.

In this case, the only option is service (technical support) from HP Authorized Service Center.

If you know where such a center is located, you can bring the machine there or ship it.

If you are not aware, you can first contact HP support for assistance to locate the nearest for you.

If your computer is under warrantly, you need to first notify HP support.

Can i still get support (phone support/assistance) from HP even if the notebook warranty has ran out? The laptop was bought in 2010.

Hello,

I am not 100% sure because it depends on support policies, the country of purchase, etc. You can try to contact them and see. If it is with expired warranty, you will probably have to pay for the service at the HP Authorized service center or consider purchasing new computer (sometimes reparing an old computer costs more than buying a new one).
