Pavilion dv7-3078nr: replacement of the fan of HP Pavilion dv7-3078nr - party?

Cooling fan does not work.  Receive 90b error message.

I plan to order a new fan, but must determine which party to the order number.  By manual:

  1. P/N 666527 - 001 (for use with computer models equipped with an AMD processor and a graphics subsystem with discrete memory)
  2. P/N 666526 - 001 (for use with computer models equipped with an AMD processor and a graphics subsystem with UMA memory)

How do I know if my laptop uses UMA or discrete memory?

The laptop has a graphics chip from ATI Mobility Radeon HD 4530 Series.  I understand that it has 512 MB of GDDR3 memory on the card.

This, I suppose that this system is considered as having discrete memory and so I should replace the fan with the part number 666527-001.

Please confirm the use of this part number or otherwise.  Thank you.

Sorry, missed his discreet

  • DV6 - 6b79el: replacement of the fan

    Hi all!
    I would like to fix my pc.

    The fan does not work, I cleaned it but still no airflow coming out.

    So I guess I'll just open the pc and just replace it, someone can help me to get the numer of replacement? Where can I order it? (I am in Italy). Or anywhere to buy a suitable fan for pc on the net.

    If it isn't too much a hassle and expensive I would substitute the battery (saw some for €50, of skirting on the official page of the HP €100, how do I get that are compatible and which not?) and so the micro, which stopped working earlier.

    Can someone show me where to find replacement numbers and order all those? (Where to get cheap options of all those suggestions are welcome).

    (I found the battery through the HP Wizard: http://support.hp.com/us-en/product/HP-Pavilion-dv6-Entertainment-Notebook-PC-series/5145688/model/5... )

    Furthermore I modernize the drive HARD and SSD, putting an 850 250 GB samsung evo, do you think that there will be compatibility problems (SATA is II on my pc, but still I see a huge gain from now and would suffice).

    Card of my pc:

    Product: A6N83EA #ABZ

    Model: dv6 - 6b79el

    I do not understand what DV6 subtype is the case, any suggestions?

    Thanks in advance to all

    Hi mate

    All Toshiba laptops parts can be ordered from the responsible ASP in your country!

    This link leads to the global database of ASP.
    http://EU.computers.Toshiba-Europe.com/cgi-bin/ToshibaCSG/generic_content.jsp?service=EU&ID=ASP_SUPPORT

    I presume that it s not possible to get only the singles the touchpad buttons, so if you want to replace the buttons, you will need to get the whole touchpad, but before you order parts you should take notice of the ASP.

  • Pavilion dv7-6c60us: issue of replacement to the Pavilion dv7-6c60us cooling fan

    Hi, so I was very sick, and having a TON of medical procedures made and until they are made my phone is my lifeline and my entertainment, etc.  So a few months back I started getting the dreaded cooling fan error 90 b at random, but now it's every time you start, I built workstations for 3D animation and editing of film/TV (which I do) from scratch and I replaced my previous laptop motherboard Dell, but it's been a while and I'm mixes returns on the research of some saying that it is easy to just replace the fan, pop the switch out, replace it and you are made to these step by step guides, saying: he basically have to go all the way to the motherboard to replace just the fan.  I wanted to just go straight to the horses mouth so to speak and know, because given my health unstable and "convalescent" until I got better in VERY VERY RURAL NC it is now a doubtful 'authorized repair shop' which is little far from me, I wonder if it is only involved should I just let - keeping in mind , I have medical bills piling up and a lot of know how myself, but maybe not the stamina, or should I hard outside - year how "hard" is to just replace the fan.  The left side of the laptop last week became really hot to the touch, whereas before there were 90 b but there was no significant difference and the unit still works, and that's all that I have here PC / computer wise and cannot not simply run out and purchase all replacement until after I'm better that might be 4 months or more? Help?

    Replace a fan in a book involves a complete disassembly of the laptop.

    If you don't have the patience and thoroughness to disassemble and reassemble then the laptop to a State because of your physical condition, I would recommend having a shop to do it for you. Consider cloning hard drive to a storage device before you leave the shop to have it.

  • How to disable or change the settings of the fan check rpm at startup?

    Hi all...

    My system features:

    HP p6180t

    Prod #: AV129AV #ABA

    Processor Q9550

    8 GB RAM

    Card mother IPIEL-A3

    Updated:

    PSU Corsair HX650W

    ASUS GeForce GTX560

    My original processor cooling fan has stopped working recently and I chose to replace it with a heat sink better while I was home. I used a Cooler Master Gemini II M4 because it was the only cooler increased capacity that would fit in my current case.

    After the installation, I got the "error: CPU fan does not, the computer now shuts down to prevent damage to the CPU." Etc... »

    My guess is that the motherboard don't like the new fan supplied with the new heat sink. The fan is bigger and I am sure that laps at a RPM lower than the stock fan. I checked my BIOS settings and do NOT have the "Hardware Monitor" section under the "Advanced" tab My BIOS is a newer level than the HP site will provide updates (mine is):

    BIOS Version/Date American Megatrends Inc. 5.09, 19/08/2009).

    Is there another way to change the speed of the fan RPM to avoid the error at startup in the BIOS?

    I am able to start the computer by using similar fan size 4 pins on the motherboard, while the proper size fan (actually mounted on the radiator) is disconnected. Even with no fan, the new radiator keeps the processor to 45 C or less through all 4 cores under load average.

    I guess I could always leave this small fan plugged into the motherboard for the BIOS to be happy and to power the CPU fan off (with an additional case fan) molex power. That would be a last option because I rather know if my CPU fan does not work...

    Any help is much appreciated, thank you!

    John

    I understand that your new fan is not detected as work correctly by the BIOS.  The BIOS does not provide all that many options to control functions such as the speed of the fan, and it's not a way to access this function to the best of my knowledge.  I'm afraid that the workaround you mentioned may be your only option with the existing fan do not have access to this setting in the BIOS.

    You mentioned that you have connected a fan of similar size to ignore the error.  Is there a RPM higher than the fan at the top of the heat sink fan?  See the pictures here, it seems that the fan is detachable and can be replaced by the fan who works with the BIOS.  It comes as the fan who gets past the BIOS will fit the heatsink.

  • DV7-6153er replacing the fan

    Hello! After 3 years of use, I found 2 cracks on the cooler fan blades. I need to replace the fan, but I need to know, to do for all portable computers dv7 series coolers are identical and compatible (for example - I found in the cooler shop for $ 4 and it is marked as compatible dv7 6000 series, it will be compatible with my dv7 6153er)?

  • HP Pavilion g6-2240sh replacing the fan

    IN BRIEF: Broken fan. A lot of noise. Hard to find part. Not made in the United Kingdom (where I live). Found supposed HP part dealer (http://uk.eetgroup.com/i/680551-001-HP-HS-FAN), do not know if its exactly the part I need. Confirm?

    If the fan on my laptop has started to make a lot of noise, to the point that even the laptop significantly sometimes vibrates. I am 100%, this is a problem of fan because I get messages that fan sometimes does not start on boot-up the top if I receive a message from the bios (click on the laptop around the exhaust Wizz it and thus he begins his work, for now). Its summer so to get a little more frequent recently. I just had this problem for a few days, closing of a week at the time of this announcement.

    I'm looking to get a spare part for the fan and replace it myself. I've never opened a laptop before, but I have a PC, a couple of times (sort of, dismantled my PC at home, updated several times, fixed things, replaced, etc. etc.). I found the service manual for my exact model and I am in contact with the person I got the laptop.

    I googled 'g6-2240sh of HP Pavilion fan' but has a lot of sites offering "HP pavilion g6-2240sh replacement fan" with no exact fan model, which is what I expected or you are looking for. So can someone tell me what it is? I was not able to find it and I don't know where is the best place to go (to the United Kingdom, I'm at Sunderland, so better order online I presume).

    P. S.

    Now, first of all, I can guarantee. 1 year international. I got in touch with HP about this, on the line to support UK. Due to my situation (student), I am quite dependent on my laptop. Unfortunately, I bought the laptop at home in Bulgaria. Then they told me that I had to their message and I more likely, logically, would have to send again, they could send somewhere else and who knows how long this may take. I know that HP has some policies on how long it may take, but my country is also, and those specific for electronics so... I found myself asked the guarantee out of the question.
    (Note: I don't know about auto repair Kits customer or whatever they were called, but after contacting the Bulgarian support line, waiting more than 10 minutes and spend a fortune on the call I left it).

    If at the end because of the time (and also a little financial forces is not able to communicate properly support at home (maybe I have to wait like an hour, but who live)) I resigned to fix myself.

    If all of the information that I could use?
    Something I am missing to tell?
    Is something not clear (his end at this time of writing, so sorry for the mistakes or difficult to understand parts)?

    Just mainly, I don't know which exact to get fan and hence, do not know what to look for on ebay/amazon/whatever.

  • Replacement for the DV7-1261WM fan

    Hey guys,.

    Recently, the top of the fan page on my DV7 grilled, or is released. I tried searching around the internet for a replacement, but I'm not really convinced on some of the websites I've come across.

    Heres the fan I do not speak of:

    Any ideas on where I can score a new fan? Thanks in advance guys!

    I think the part you want is number 488885-001, according to the guide of service (below)

    You can also try the Intel version...  480481-001. these can be found on ebay for as little as $5.  The HP parts store seems to suggest it would work too, they are listed as part of sale for your model.

    Manual service and repair procedures can be found at http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c01918142/c01918142.pdf

    Unfortunately, it's a pretty complicated process to replace the fan.  If you're not a techie or have experience in the repair of laptops, you can go to a repair shop authorized HP.
