Question about HP Pavilion dv9000z Notebook

1 Answer

No Power This laptop has been driving me insane! It was overheating and caused all sorts of issues, finally I braved it out and did some work myself after paying way too much money for no help at all! I cleaned a clump of debris in the fan, put everything back together, and it worked just fine! Except the mouse pad didn't work. I was tempted to just live with an external mouse, which worked just fine, but of course I was too stubborn to stop while I was ahead. I opened the laptop again, and here's where the old phrase ''you learn from your mistakes'' is making a lot of sense to me, I turned on the power and started the laptop, all while I was looking at the motherboard and seeing which LEDs lit up and which didn't. I'm not sure what I touched or what happened, but the laptop turned off. But the power light was still on, so I held the button down until it shut down completely. I decided to put everything back together and try again. This time when I plug in the AC cord, the blue light circling the AC input on the side of the laptop lights up, but the little blue LED on the front left side indicating that the battery is charging, is no longer lighting up. I try the power button to boot the machine, and I get nothing. Any bones you can throw me ? I'm afraid I may have fried something by messing around with the power on. How do I diagnose ? How can I tell if the motherboard died, or if something else happened ? Also, I noticed that the display Lid Switch module circuit has some damage, which I plan to replace. Would this cause the problems I'm describing ? If I replace that, do you think it may fix it ? Thanks for any help! (sorry for the long post, I'm venting. :-))

Hi there! Venting is good! It lets out all bad aura from you... Anyways, moving on, try this simple step first:

Remove the battery and unplug the ac adapter then press and hold down the power button for about 10 seconds to drain any power from the system. Then set the battery aside, plug the AC adapter in and power up the system. If the system turns on, you need to replace the battery. Battery life is only 1-1 and a half years only. you're lucky if the battery is still usable if you reached 2 years.

If it doesn't power up, then try to replace the reed switch. If nothing still happens then you got a fired motherboard and you need to replace the mobo or better yet, look for a new laptop.

Just my 2 cents...

Hope it helps!

^_^

I have a horizontal white line going straight across my laptop, and I only got it a few days ago. Is there anyway that I can sort this out myself. Thanks x


Hook a external monitor to the video output on the back of the laptop, if it works! you have a laptop screen issue, possibly caused by a loose video cable that connects from the motherboard to the LCD screen, if the monitor has the same problem it is a motherboard issue. Doing anything to the laptop "dis-assembly" will void the warranty, best to take it back for exchange.

Tip

Dealing with Laptop Overheating Issues


To minimize the chances of laptop overheating, you may follow these steps:

Always place your laptop on a flat, hard surface like a table etc. that allows for free ventilation.

Don't place your laptop on blankets or other soft surfaces that can block the fans and air vents on the bottom of the laptop.

Clean the ventilation slots of your laptop at regular intervals with compressed air to free them up of any deposits of dirt, dust etc.

The machine will perform much better in climate controlled environment like Air Conditioned rooms.

Regulate and optimize the power management settings suitably so that the heat generating parts – such as the LCD and storage disc drives – get into the low power state if they are not accessed for a defined period of time.

Install monitoring applications on the laptop that enables you to track the temperatures of processors, hard drives and other
system components. Knowing the root cause will help you to manage the machine more effectively.

If find necessary, you should use a laptop cooling device or a stand for raising your laptop to minimize the chances of heating.

If you are facing overheating issues and the laptop is covered under warranty from the manufacturer, report the problems so that the issue can be resolved.

This should help in managing the overheating issues to a large extent.

I have been having trouble turning on laptop. I push and push on the power button but it won't turn on. Then the next time it will finally turn on. It keeps getting worse each time the laptop is turned...


Yes, this is a power switch that is not working properly and neeeds replacement. Contact your Dell manufacturer and see if it can be repaired. I not familiar with the B130 but I have worked on some other Dell models and they seems to have the same issue for power on . the micro switch just gives out and the switch usually has to be replaced.

My pavilion dv7 is saying "boot device not found". It is saying there is "no hard disk". Any suggestions appreciated.


I would want you to tell me if your Laptop feels hotter than usual.

If so... this in combination with the Boot device not found message means you may have two problems.

1: The hard disc is failing

2: Your cooling fan isn't working

Either one could cause the other to fail. If the hard drive is overheating the cooling fan may not be able to keep it cool enough to function properly,


If the cooling fan isn't working properly or the cooling vents are clogged the hard drive and/or the intergrated circuitry could be overheating

If you do not sense any over heating.

You hard drive may have crashed, if you have another one you can put in the laptop to see if it is recognized.

Would help to have some sort of disc you can boot off of that would recognize a hard drive such as a Linux live CD or Hiren's boot CD or some sort of PE disc. Maybe a Windows install disc. to try and find out the cause.

Good Luck

Will not turn on as error code no 14


simple answer. Little resetable fuse on power board, F5 as i remember. It causes the display board to go insane as it doesn't provide enough power to the board. Solder a 2amp one across it. I nicked one from an old computer motherboard USB fuse(usually mounted next to each usb socket). SORTED! was an issue with 2007/8 fridges, especially if you had solar panels fitted tgo your caravan!!!! :)

Overheating issue - looking for service manual


I had the same problem. And i believe my method has the fix.

On the bottom side of the laptop, unscrew the door to access the CPU Fan....(closest to the power supply)
Make sure the system is OFF and not plugged in or no battery in.

You will see 2 tabs on the copper heat sync that holds it down to the cpu.
Unscrew both the visible tabs.
Bend Both Tabs upward to where when you screw it back down there will be resistance.
What that will do is secure the heatsync to the die of the CPU.

replace the CPU door, and start her up.
Hope this helps ya'll
