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??

  • Gregg Gustin Apr 04, 2011

    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.

My HP Pavilion a000 is turning on, but has a black screen. I looked at the possible problems, and sure enough, some of the capacitors were leaking. Problem is, how do I replace these capacitors? Do I...


we are fixya not HP, so.... why ask here? and not HP real>?
OLD DESKTOP?: a000 is not the real model , only part.'
is this PC ,13 years old. ?
not even the word desktop stated once, wow.
my wild guess is it is a DT, due to super easy motherboard viewings. if not , say so please..

no full service tag stated, it has model and full p/n on it.
See my photo at end. (long post) lacking that.
HP made VAST pc with A000 , as part of much larger P/n
tag line 1 ,3 and 5 tells the helper what is REALLY there.
it even tells us if the parts are for USA. are you?

NO OS STATED in your post.
a000 is a very old PC and has the CAP disease, the china clone caps classical failure.. (well known) 1999 to 2003
https://en.wikipedia.org/wiki/Capacitor_plague
so many questions, who fix it, why not just buy another newer PC, that has w7 on it already, the one that is not a virus magnet like XP. (or VISTA junk) W7/8/10 years.

you will not replace the caps easy, (takes special tools) {I can}
there are no new motherboards, HP does not sell things this old.
that leaves used, or (omg NOS) motherboards with the same useless China noname caps in it, why go there? avoid this and run from the box. (I would)

the unstated OS , is problematic here, XP will not let you change the mobo, and MS stopped taking calls in XP and VISTA>
so cant force activation that way, why go down this path.?
what I'd do is buy a usde PC with W7 coa sticker on this side
or newer' (COA is the OS license from MS)

for $100 or near, i can find a PC desktop. that is
vastly better that yours.
but if compelled to run bad motherboards same year.
then if I had your service tag , i could in fact point to them sold used, and be a match , exactly, the HP parts surfer lets me do that.(ask)_

first tell what OS is there? of the 14 used.
then post full service tag for 10x batter answers.
in 2006 HP added the new F11 key. started the year 2006
so if PC is that or newer the F11 recovery key works and you dont need any
HP (unstated) OS(unstated) install media (CDs)
see? how that service tag is magical?

what I'd do is get a newer PC. I bet yours is 2003 or older, i do.
here is the best solution for an upgrade.
id never buy any MOBO with those caps onboard. EVER.
here are some great whys to get a better machine
and not go broke.

LEGACY PAIN: my wild guess , is yours is here.?
off the HP legacy page? if use scrap it.

what is your 1,3,5? only this matters, first. and unstated
next is OS, what OS is running any PC from HP runs 6 or more OS
sold new, even linux ,freedos and P/S2 ! and w95 up
tag_service1-1iohaobt0khnrlk3utl25c3h-4-0.jpg tell more and get x10 better responses !
Like do you need mobility?
do you need W10 or 64bit support. (be wise)
do you want the PC to last 10 more years? or 1 week.
what APPS do you run if any, or only use IE6 the virus magnet.
do you use the internet (LOL)
do you need the MS CLOUD.
the list is endless but this is basic.
did you ask friends if they have a used PC they don't want
or would sell for $10?

My Hp Pavilion dv2700 has a display error, it boots and then it starts to flicker, freeze and then again unfreezes. and sometimes it even goes blank. this is the third HP laptop i have seen with so much...


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
