Question about HP Computers & Internet

1 Answer

I am changing the motherboard of my hp pavilion dv7 2173-cl but i've found that the old one was overheated and because of that it broke down. How do i check if the fan still works? besides the rubber (i think) separators have melt, it doesn't matter, or should i get new of those to assembly the laptop again? they separate the fan from the motherboard

Unfortunately HP has has an overheating problem with their laptops for years. Machines often get hot enough to melt the solder and other parts on the motherboard . This often results in faults ranging from system shutdown to audio problems to complete failure. They have not addressed this issue adequately.

It would be best to replace any parts that show heat damage. You can verify that the fan is working by hearing it run. Also your bios should show if the fan is operational. Alternately, there are several free utilities such as Mother Board Monitor that can monitor CPU temperature, fan operation and system condition.

Don't be surprised if even after replacing the motherboard, the system still overheats. Using a cooling pad and assuring the vents are clean and clear of obstructions may help.

    yes i've heard these laptops have that problem. My question is how can I replace that small square rubber piece and what is it for. It is on the microprocessor beneath the copper wires that take the heat to the fan. I live in argentina and it is very difficult for me to get the original part. Thank you for your answer!

    I read it is a thermal grease. where do i get that??

    Your best bet would be to contact HP on their website to see if the part is available. They can be expensive though. So you may just want to get their part number then contact small local computer shops who often have older parts available and will sometimes sell them very cheaply.

Honestly, try harder. If you've taken the thing apart, you're more than half way there. You probably just need to unscrew more stuff and pry more parts out.

Sometimes with HP laptops I have seen issues with the ribbon cable that connects the screen to the motherboard. It is quite a project to get to the connector but it is best described as a compression fit connector that the ribbon cable slides into.

The other issue with this model is cooling for the video card. Being compact and crammed in the laptop case the cooling fan may be clogged causing it to overheat. Check to make sure all cooling ports are clear.

The last item if it has been overheating could lead to a motherboard or video board replacement. If the unit has been overheating for some time it will cause the components to fail.

Will new micro atx boards fit inside of a hp 4550z case?


Yes i think you will be ok as i can see and your old motherboard is microatx but i strongly recommend you to change case because is not only about motherboard.You will need and better and new power supply and if you want to build a good system with air flow for not overheating your new cpu and other hardware i strongly recommend you to change and chassis!!You can find a "nice" case with $50-$70 bucks if you dont want to spend money on case,but you will need power supply for sure

Battery is not charging


Portable batteries are a consumable item and have an average lifespan of 300 to 500 recharge/discharge cycles.

If the computer is only 10 months old, contact HP for a replacement after following the instructions for the HP Battery Check HERE

HP pavilion laptop shuts down abruptly


It sounds like something is overheating to me. Also, it could be a bad motherboard. Try putting your laptop on a hard surface. I carnt stress this enough. Also, you can try cleaning out the laptops cooling vents with some compressed air (you can get it at pcworld). At the end of the day and it still wont work, send it in for repair. Good luck
