A Little Advice

Hey Computer Forum,

So I have this laptop for a customer - an HP Pavilion dv9000 (dv9205us to be exact).

It doesn't turn on. He bought a new power adapter for it, still nothing. When you hit the power button, the LEDs come on for a split-second and then turn off.

I tried removing the battery and trying it, then I unplugged the CMOS battery for 30 minutes and tried it, no luck. I took the whole thing apart and put it back together - everything looked fine (no discoloration, melted wires, etc).

All I know to do is to replace the board. I sent him an email and told him to order this one:

But now I'm wondering "what if I put the board in and it does the same thing?"
I guess I could return it for a restocking fee, but meh...


What do you guys think? Should that work? Is there something else I should have tried?

The power port on the board isn't loose is it? I know that on my mom's old HP, that is what killed it.
 
No, the blue light around the port stays on the whole time it's connected. It's a very solid connection, and it "tries" to come on every time you hit the power button exactly the same - It seems like it's getting a "kill" signal from the mobo the instant it gets power... I dunno... guess I'll just wait on the new board and cross my fingers. I can't think of any reason why it <i>wouldn't</i> work, but I guess we'll see...

Yeah, well good luck. And in case you missed it, you used the wrong bracets for the italics. ;)
 
*bump*

I was hoping to maybe hear from johnb35 or some other repair gurus on this... or is it that I've just exhausted my options and I'm trying the only feasible thing left to try...

The guy went ahead and ordered the motherboard, so I guess it doesn't matter now... just keep my fingers crossed. I just found out that before it quit turning on, he was having problems with it booting up and the wireless going out - both problems are symptomatic of a hot mobo. So I guess what I'm worried about now...

Do you think the processor may be fried, not the mobo? What would be the symptoms of either problem?

Will replacing the motherboard work?

Do you just use regular thermal paste on laptop processors? (I've tore apart hundreds of PCs, but I try to avoid lappys... I'm kinda a "noob" in this area...)
 
I know HP has had problems with some of their laptops and the wireless going out on it. I think there was bad airflow and it kept burning out the wireless cards or something along those lines. Motherboard and wireless card changes worked for awhile but same problem in the end. So the new motherboard may or may not work.

This would be the only info I can contribute at this time.

I'll see if I can't find what model numbers they were having issues with and post back.
 
I know the dv6000s were on recall for that very problem - I fixed one a while back. If the dv9000 crashed because it was running too hot, then that means the board is faulty by design, so even if I replace it, it may go out again. What do you think I can do to keep it cooler? I was thinking of putting some sort of "feet" on the back of the laptop so that the fan can breathe, and I was thinking of wrapping electrical tape around the wireless card for a little insulation against the hot board. Any other ideas?
 
Not on the list. But the problem was likely heat-related. Any other ideas on how to keep it running cool (or cooler at least?)
 
Yeah, I thought about that - it's kind of like suffocating it really. Well, maybe with some fresh Arctic Silver and proper airflow (these things basically sit right on top of the fan - engineers were smoking dope?) it will run cool enough. If the board isn't overheating, then it shouldn't fry the wifi card. And I may find some other way to buffer the heat from it...
(and it is on the list - I missed it. But chances are his warranty is long expired - I think these computers came out 4 years ago, and the "free repair" is only good for 24 months as far as I can tell. Same thing happened to the dv6000 I had to do work on - she missed it by 6 mos.)
