Jess :

Hi, thank you for using JustAnswer.com. I am glad to assist you today.

Customer :

Thanks, XXXXX XXXXX really appreciate your assistance.

Jess :

We are not HP, we are from JustAnswer. We will try to sort out the problem

Jess :

Ok...

Jess :

When you plug in your power adapter, did you see the LED lit indicating the power adapter get power from the mains?

Jess :

We need to isolate the problem whether it is the laptop or the adapter

Customer :

The LEDs (all 3) are flashing when the adaptor is plugged in.

Jess :

Ok... Do you see the LED in the adapter itself? Just plug the adapter to the main do not plug it yet to the laptop

Customer :

The adaptor doesn't have an LED at all.

Jess :

Ok...

Jess :

Now, remove the laptop battery and plug the adapter

Customer :

Ok......done. No LEDs are lit.

Jess :

Ok... When the battery is removed, no leds are lit?

Jess :

Ok do this:

Customer :

Yes, that's correct.

Jess :

1. Remove the battery
2. Unplug the adapter from the laptop
3. Press and hold the POWER button for about 30 seconds

Customer :

Okay.........standby.

Customer :

Okay, I pressed the power button for 30 seconds. Should I reinsert the battery now and try it again?

Jess :

Ok. Insert the battery and do not plug the power adapter.

Jess :

Turn on the laptop in battery only

Customer :

Okay, done.

Jess :

the same problem?

Customer :

Yes, same problem when the AC adaptor is plugged in.

Jess :

No. Power it with battery only

Jess :

Same problem?

Customer :

The laptop won't power up at all without it. Yes, same problem.

Jess :

Ok... So the laptop won't run on battery? Can you confirm if this battery has been charged recently?

Customer :

Yes, it won't run on the battery separately. The battery was charged for several hours yesterday.

Jess :

Ok. Now when you turn on the laptop with the adapter, same thing happens? ALL LEDS are lit?

Customer :

Yes, that's correct. The LEDs are flashing and they never stay lit.

Jess :

Ok... This behavior is a sign of a faulty motherboard

Customer :

Some more info for you..........the laptop starts to power up for a fraction of 1 second and then it powers down.

Jess :

Yeah... this is a sign of a faulty motherboard... Is this under warranty?

Customer :

I believe that the warranty has expired.

Customer :

By the way, I also tried using another adaptor (same model) yesterday and I get the same result.

Jess :

Oh ok... I am very sorry but as to my knowledge, this is a motherboard fault. The motherboard needs to be replaced

Customer :

Okay. Is there anything else that I can try at this time?

Jess :

Nothing. Turning ON and OFF your computer can only hard the data in your hard disk

Jess :

But, you can try further but please remove your hard disk

Jess :

Try to:

Jess :

1. First, remove your hard disk drive
2. Remove your RAM. If you have 2 RAMs, remove 1 RAM and test

Jess :

But make sure the hard disk is disconnected for data safety

Customer :

Okay. I'll give that a try. Also, I'll check with HP about replacing the motherboard. Thanks a bunch for your assistance, Jess. I have another question..........

Jess :

Ok please....

Customer :

This is my first visit. My understanding is that I can utilize this service for the next 30 days for free (I chose that option). Hopefully I won't continue to be charged thereafter.

Jess :

Ok. I am sorry but I don't know about the charges here... You can email the moderators for this advise...

Customer :

Okay, I'll contact them. In all do respect, I would like to "accept" your advice in the Feedback section. However, I'm still experiencing the same issue.

Jess :

Yeah. I believe that your HP board really needs replacement. I myself did experience that with my Pavilion DV2000

Jess :

Same signs that you have now. All LEDs are lit and flashing. It start for a while and the nothing...

Customer :

Yes, same thing. The power cuts off in about 1 second.

Jess :

Yeah... The board could be shorted or something. I was watching movies then... 3 movies in a row... Perhaps that triggered the board to retire

Customer :

Bummer! Question about the $24 support fee...........Does this apply to my inquiry for today?

Jess :

Yeah... As I know, charges are per question basis

Jess :

But you can choose not to accept an answer if it is not helpful

Customer :

Okay, I guess that's all for now. Thanks again for your help, Jess, and have a nice evening.

Jess :

Ok... Thank you for using JustAnswer.

Customer :

Thanks again............I'll use this service again in the near future.

Jess :

Ok. I am glad for that.
