My HP Pavilion DV 6000 wont start

saraocallaghan

Hey guys,

I have a question/cry for help. As mentioned above my HP pavilion dv 6000 won't start. When I press the power button the blue lights under the screen light up, there's a clicking sound from the disk drive and the fan runs for about 3 seconds before powering off. There is no life from the screen, nothing.

I was wondering if anyone has had any experience of this or knows what to do? Or is my beloved laptop dead and gone. I'm not particularly techie minded but I'm looking for a light at the end of the tunnel.(oh I run Linux and XP on a partition, I'm not sure what service pack of XP I'm running)

Thanks for your help.

Have you tried turning it off and back on again.....?

She's f**ked as far as i can see, check the battery/plug it in

I've tried turning it off and on again. I've tried turning it on while plugged in and also when unplugged and the same thing happens.

Sounds to me like it might be a dead hard drive. One cause of ticking is when your hard drive dies. Maybe try removing the HDD and see can you boot into bios without it installed.

If it's just the HDD then you will only need to buy a new one which won't be too expensive.

Quite possibly graphics chip is faulty. Caused by overheating. Seen this many, many time with same symptoms!

That happened to my laptop three years ago. The same laptop as well. They told me it was a faulty motherboard.

It was under two years warranty so got it fixed for free. Working fine ever since.

The cooked graphics chip was such an issue on these DV6000 machines that HP extended the warranty for an extra year to cover the problem!

This problem can also cause the wireless card to overheat and fail!

Check your laptop specs, if you have nvidia gpu then probably this is the case. It can be fixed under 100 euro but if not done right it will fail again.

That's the graphics card that I have. I really hope that is the cause. Thanks for your help everyone.

Totally agree, dodgy nvidia chip

Got my board swapped in the first year too. It's a fine little machine but it's bruised and beaten from me dropping it the first time (the only time!) and taking it apart to among other things replace the screen, upgrade the RAM and clean it thoroughly from the inside out.

Aside from the GPU issue which wasnt really HPs fault it's not a bad laptop. My only complaint with it now is it just had it's 4th birthday and now the Display inverter has shown signs it could die any day now. Having said that though, that inverter has been sick for over a year now. Or it's the damn LCD cable, which sucks, because the inverter is a $10 fix and the cable is a $50 fix.

saraocallaghan please post exact model of your laptop.
If you have nvidia GPU, ONLY right way to repair it, is replace faulty chipset with brand new manufactured after 2009.

The model of my laptop is a HP Pavilion DV 6000.

I fix them regularly, one every month or two. Replacing GPU with newer version is the best solution but usually uneconomic. Cheaper (under 100e) solution to the problem is:

1. Reflow (proper reflow, not ovens or gas torches)
2. Slight modification of cooling unit to increase heat conductivity
3. BIOS upgrade
4. Use cooling pad
5. Lower CPU voltage with RMclock (this also helps to keep GPU cooler as both CPU and GPU in this laptop uses the same heatpipe)

saraocallaghan - You should have white sticker on bottom of your laptop, and exact model should looks like dv6285eu

Reflow should never be method of repair and I can give many reasons for it.
I have already wrote in other thread why replacing chipset is the only proper way to fix nvidia issue. http://www.boards.ie/vbulletin/showthread.php?t=2056370785

What kind of modifications?

3. BIOS upgrade

By doing this, fan will work more frequently, to keep temp more stable. For example- instead of 55-65C it will keep 58-61C due to lower thermal expansion of chipset. But we are talking about laptop that is not booting up, so even if you take BIOS chipset and program it using external programmer, problem stays.

In what purpose you want to put broken laptop on cooling pad?

It is great solution to decrease performance and maybe some kind of prevention.

Only first solution might bring machine back to life for short while. Rest of your points (except second because I don't get what you mean) are good advices for somebody, that have never had problem with graphic chipset.

No stock on the board sadly but this site has the list of all the parts on the DV6000 right down to the screws. Something to keep in mind if you break your charger port: it can be replaced for $12.

PapaSierra

What kind of modifications?

HP decided to use high thermal conductivity foam between GPU. It wouldn't be a bad idea if not a problem with overheating nvidia chipset. I replace it with a copper shim to increase thermal conductivity.

By doing this, fan will work more frequently, to keep temp more stable. For example- instead of 55-65C it will keep 58-61C due to lower thermal expansion of chipset.

Update BIOS after successful reflow

In what purpose you want to put broken laptop on cooling pad?

Again, after successful reflow

It is great solution to decrease performance and maybe some kind of prevention.

It significantly lowers CPU temperature and in case of DV6000 (I own one myself) also GPU temp. I can't see how lowering CPU voltage can lower performance? CPU voltage specified by manufacturer is a average voltage on which average CPU works fine increased by a safety margin. Undervolting is nothing else then finding a minimum voltage on which your particular CPU stays stable. It doesn't affect CPU performance.

In general I agree with you, reflow on it's own will not completely fix the problem as the chipset will still have the same faulty design. As a result of this chipset will keep producing more heat than it should and finally causing the same cracking of BGA. But if you take all the extra steps to prevent overheating ,like copper shim, bios update, thermal pad and lower cpu voltage the problem should't repeat.

And finally 2 additional advises to DV600 users:
1. Make sure you clean the fan and radiator in your laptop regularly (every year or so) with air duster to prevent overheating (actually that's a good advice for all laptop users)
2. If you use DV6000 for gaming STOP!!! Sell it immediately and buy another laptop or desktop PC. Playing any games other then minesweeper on DV6000 will kill it sooner rather then later.

PapaSierra you wrote in first post that solution is reflow and some modifications and it cost €100 or less.
Now you are saying that it will not fix the problem, but extra steps will prevent it.

So as a customer I pay €100 and:
- I need to install and config extra software
- buy extra cooling pad
- I can not play any game
- hear that "the problem should't repeat."
-
- enjoy my repaired laptop

Problem with nvidia has nothing to do with BGA balls.

PapaSierra

As a customer you pay €80 and I install and configure that software for you. Then you buy cooling pad for under €20. And yes, you shouldn't play games on that laptop not only after my repair but even before it when laptop was new and that's not my fault, please complain to HP.

Problem with nvidia has nothing to do with BGA balls.

So can you, please, explain or provide a link to detailed explanation of the problem? As far as I'm aware badly designed nvidia chipset produces too much heat and that heat causes failures of lead free solder underneath the chip (lead-free solder is known to be more brittle than lead-tin solder). Right or wrong?

themonic

I did. I've paste link in second post in this thread. There you will find my explanation and link to article.
Leaded solder is more durable, flexible, reliable and more resistant for cracks and oxidation than lead- free solder.
Leaded solder (actually Pb and five other elements) is prohibited for manufacturing due to RoHS regulations adopted in February 2003 by the EU.
