Fan replacement CQ56-115DX

I need to replace the fan on my HP/Compaq Presario CQ56-115DX Notebook. I have tried to open the case. I removed all the screws from the back. I removed the battery, the memory cards, the disk drive and all screws in these compartments. The edges of the keyboard will unsnap with fingernail pressure and I can lift it a half inch or so all the way around. But there appears to be some kind of screw or other fastener close to the middle of the computer. I looked diligently but can not see where this fastener is. I used a moderate amount of force, but do not want to crack anything.
How do I loosen this final fastener so I can get into this laptop? 
I could not find an appropriate forum for this question. You need a mechanical forum for the laptops.

Here is the Service Manual:

Look particularly at page 47 which shows the screws holding down the keyboard.

  • Can I replace the keyboard of CQ56-115DX?

    Hi,  I have a brand new CQ56-115DX. It comes with a non-standard keyboard which makes typing quite inconvenient---I am used to the standard keyboard and frequently hit the quick  launch keys when I need to use "Tab", "Shift" and "Ctrl".
    This is very annoying to me.  I would like to replace the keyboard with for example: the keyboard for CQ61.
    Can you let me know if the CQ61 keyboard would be compatible?   If not, is there any other compatible standard keyboard that I can use?   I know how to replace the keyboard just need to find compatible parts. Thanks.

    You can find list of compatible parts for this model over here

  • New hard drive install on compaq cq56-115dx laptop

    the 250gb hard drive on my compaq presario cq56-115dx failed after 3 years.  i have installed a new hard drive and used the compaq recovery disks 1-4 to do a system install option.  everything ran fine during the installs of the disks and even prompted me to remove disks so the rest of the configuration could take place.
    right now, the laptop has been on over an hour with the lcd screen lit up but it is blank.  the fan is running and i have yet to see the indicator light flash for the hard drive. 
    i cannot tell if anything is going on.  really nervous about this.
    how long can this go on? 
    how will i know if the recovery has failed in any way?
    is there anyway to restart the process over again?
    what are my options?

    I have a Compaq Presario CQ 56-115DX that has just turned 3 years old and the hard drive apparently has gone bad . I'm trying to fond instructions on how to install the new upgrade , and where the best place close to me would be to find one would be ! I'm in central Florida in the 33880 area code . And what about the installation ? I can't seem to find anything on this pc . I really like the pc and want to keep it ! I hate Windows 8 ! Sheesh

  • Compaq Presario CQ56-115DX Problems

    Hello,
    I have a Compaq Presario CQ56-115DX Laptop. It is still under warranty. Within the last week the power of the laptop has been messed up. When I have the laptop unplugged, which I don't very often, the laptop shuts down after an hour without any warning. So I plug back in the laptop and it still shows anywhere for 40-70 percent battery left. Why is it doing this?
    Thanks

    Hi,
    First of all, shut down the notebook, unplug the AC Adapter, remove the battery, and then hold down the Power button for a full minute.
    Now, plug in the AC Adapter without the battery inserted, start the notebook, open windows Control Panel, open Device Manager, expand the entry for Batteries, right click on and the Microsoft ACPI Compliant Control Method Battery and select Uninstall - do not uninstall anything else here.  When the uninstall is complete, shut the notebook down, unplug the AC Adapter, re-insert the battery and then start the PC on just the battery.  Windows will automatically reinstall the driver - leave Windows running for a few minutes. Shut down the PC again.  Now plug in the AC Adapter ( with the battery still inserted ) and start the notebook to see if this has helped the issue at all.
    If the above has not helped, download and run the stand-alone battery test utility available on the page below and see if this reports any problems with your battery.
    http://h20239.www2.hp.com/techcenter/battery/battery_ts.htm
    If this reports a problem with the battery ( or even if it doesn't, but the problem is still occuring ), contact HP and arrange to have the battery replaced/notebook repaired under warranty.
    If you live in the US, contact HP Here.
    If you are in another part of the world, start Here.

  • Compaq Laptop Model: CQ56-115DX versus Toshiba Netbook Model: NB505-N500BL

    I'm looking to see which one of these is best on performance only since I know the laptop is bigger then the netbook. Both are the same price. It seems like the Compaq would be a no brainer until you read the reviews on each. Toshiba has better reviews by far even though the Compaq looks more powerful from the specs. This would mainly be used for web browsing and facebook gaming. Any help would be appreciated. Thanks.

    Hello,
    Best Buy has brought your posting to my attention as you would like to purchase from Best Buy the HP CQ56-115DX versus a Toshiba netbook.   I am pleased to know that you are interested in purchasing an HP notebook.  HP is very proud of its line of products which its reps are encouraged to promote without criticizing its competitors.   The two products are different.  Do want a notebook or a netbook?  Redwyv provides a valuable posting of the pros and cons in:
    http://www.forums.bestbuy.com/t5/Computers-Home-Networking/Help-What-laptop-is-right-for-me/m-p/2815...
    You will see in the above link, the similarly priced HP Mini Netbook, Model 210.
    And as Redwyv has stated in this posting, you do have 14 days to return the product to Best Buy. 
    Based on your posting, I probably shouldn't distract you from your two choices as it appears you have already done your own research and have narrowed down your choice based primarily on price.  I am sure you have noticed the significant difference in screen size and memory.  You mentioned doing some Facebook gaming.  The fact that you specified "Facebook gaming" indicates you are aware of the requirements for more "intensive" (for lack of a better word) gaming.
    You do comment that the HP laptop is certainly more powerful, but you have read negative reviews.  There are also some very strong reviews for the CQ56-115DX.  You can find a summary of reviews at:

  • Idle Fan speed 4400 RPM after fan replacement

    Several months ago the left side fan on my MBP died as the result of a worn bearing. The computer is covered under Apple Care so I sent it in to have the fan replaced. Ever since the fan was replaced the idle speed on both fans is in excess of 4K rpm even when the CPU shows minimal activity. SMC fan control is set to 2K rpm. iStat Nano widget displays temperature at 120 Degrees Fahrenheit and fan speed at 4500K. I took my MBP back to my local Apple authorized service center and told them what was occurring since having the fan replaced. From Hardin Apple service center in Arlington my MBP was shipped to Houston Texas where Apple Service Technicians replaced the Logic board. I have since reset the PMU by removing the battery and holding down the power button for 5 seconds. I have also run the Apple Hardware Diagnostic test using the install disc which showed no hardware malfunctions.
    With the CPU 95% idle the fans should not be running anywhere near 4K. Despite two trips to Apple Service my MPB still has a fan probably which is not only annoying because of the increased noise but it is affecting my battery life as well. If anyone has any ideas as to how to fix this problem which I have not already attempted please post them. I am hesitant to send my MBP back for more service at this time due to their failure to fix the problem the first time or check the results. They were aware of the problem when I sent it in for service and when they returned it to me the same problem persisted. This type of service does not inspire customer confidence.

    I'd be inclined to try an "archive and install" of the OS, Jason, and leave off any third party "add ons" like SMC fan control for the moment.
    Alternatively if you have an external HD then you could try installing a "clean" copy of the OS on this and using it as the boot drive, to see if this overcomes the problem
    There are OS software elements to the process of fanspeed control and if these are corrupted then the fans are likely to run at "failsafe" speed.
    Another possibility may be that a temp sensor hasn't been properly re-connected, again resulting in "failsafe" sped operation.

  • T43p Cooling Fan Replacement

    Hi all,
    Have a noisey cooling fan on my T43p-2686-DHU.  So, have puchased from Lenovo part 26R9074 "long fan 24".
    Before, I open my Thinkpad for the first time.  Was wondering if someone has instructions on how to do this repair, pointer to pitfalls, or comments.
    Thanks in advance,

  • Compaq CQ56-115DX Recalled Power Supply & Dead Motherboard

    Hello,
         We currently have a Compaq CQ56-115DX in our shop that we are diagnosing. Currently the computer turns on and sits at a black screen while the caps lock light blinks repeatedly. Upon further research we have found that it may have an issue with the bios. We are unable to get anywhere past that black screen so we cannot update the bios. We have tried pulling the CMOS battery and letting it sit for a bit in hopes that it might reset the bios. Unfortunately that didn't work. We believe the motherboard is bad. Looking at the support page for more resources I saw that there was a recall on the power supply for this machine. I went through the confirmation pages and the adapter is one of the affected models. Is there a possibility that the power supply could have caused the motherboard issue?
    Thanks,
         ST

    It is actually a recall on the cord from the power supply brick to the wall plug, not the brick itself. If that goes bad you just get no power at all so the power supply is not the likely culprit. Is there any evidence of melting or arcing on the power supply at the place where the wall cord plugs into the brick? Does it put out power to specs? I would agree with your motherboard diagnosis, by the way. 

  • R61i fan replaced, now goes into standby every 20 to 25 minutes

    First post on this forum. Having paid a tech ($$$!) to come to my home to replace the fan, I've had the additional issue of standbys occurring at least once per hour which are without a clean power down option, only unplugging the machine actually works. The tech denies that this issue is related to the fan replacement. Friends (non R61i users) say it's overheating or possibly the heat sink is not correctly positioned. Is this machine worth trying to repair? Yes it's old and an XP but my situation is such that I need guidance as to my next step. Any help appreciated.

    I have replaced the fan on my R61 myself 3 times. It failed the first time when it was 4 years old, and each time I replaced it with a used fan bought on EBAY. Maybe they were too used. All you need to do it yourself is a copy of a few pages from the Hardware Maintenance Manual, a tube of thermal paste, a screw driver and about 30 minutes of your time.
    The last time it failed, I did not replace it. I bought a can of compressed air, and blew it over the fan blades, which were heavily coated with dust, and it has been working fine since then (although I do have a spare waiting to be used just in case).  
    I am thinking that possibly, the thermal paste was not reapplied correctly. You cannot have a heat sink not correctly positioned on an R61 as the fan and heat sink are one unit, and fit tightly in position. There are many vidoes on the internet that will show you haw to change a fan.
    Good luck.

  • Do I need my fan replaced?

    My fans recently have started making a much louder, more scratcy noise. It is not the macs fan simply speeding up as it happens even at low rpms around 2000. I am not sertain on this but I think my fans need lunbricating or replacing. Is this covered in the 1 year warrenty that came with the macbook pro. And on a side note does anyone know if apple would repair it even if I have bought it from John Lewis (somethink like best buy for you amercans).
    Thanks for your replays in advance.

    Your one-year warranty is good at any Apple Store or AASP. You may need your fans replaced if you've already blown them out. I wouldn't try any lubricant - just take your unit into your local Apple Store and let them 'hear' the problem.
    Good luck,

  • Portege 3490CT - Fan replacement

    My portege has started freezing after about 10-15mins of use and the internal fan doesn't seem to be kicking in any more.
    I am assuming it's the fan that is causing the problem as the screen stays the same (i.e probably not graphics problem) and there are no odd blue screens or errors and CTRL ALT DEL does nothing..
    I've had the laptop apart and checked for dust and the fan connection and it all seems ok.
    Is it possible to pickup a fan assembly on it's own, or does it come attached to the heatpipe (it's back together now and can't remember what it looks like!)
    Do the entire 3400 series use the same fan assembly?
    Apologies for all the questions but i really need my little laptop working again
    Many thanks :)

    Hi
    It seems that your notebook hangs or shuts down because of high temperature inside of notebook. Mostly this issue happens because of dust and dirt. The fans cannot work with the full performance. I dont think that you need to replace the cooling module. Maybe the full clearing of the module and fans will solve the problems. Check also the settings in the power saver.
    Im not 100% sure about the fan replacing on this unit because I dont know if its only a fan or the whole module which must be removed. But the best way to find it out is to contact the Toshiba service. There you can also order the new and compatible parts.

  • Laptop Fan Replaced But Fan isn't working

    Hello Hp forum members, a few months ago my laptop's fan suddenly stopped working (the cause was probably lack of cleaning so the fans were clogged and ended up destroying its own motor) and I received the error messages on startup. So I got my fan replaced but now the error messages are gone but my fans aren't even on so I still have an overheating problem.

  • Fan replacements/upgrade for MDD Power Mag G4-suggestions please!

    First, I apologize for again bringing up what has been a frequently discussed topic. (ad nauseum?) I tried to do some homework first but I'd like a little help if anyone has some recent experience.
    I am looking to change out the large main CPU heat sink fan and possibly the two power supply unit fans in my pair of MDD Power Mac G4s. The specs are Dual 1.25ghz (fw400) MDD G4. One has a 400watt actel PSU and another has a samsung 360watt PSU. Both large CPU case fans seem to be the original delta models installed by apple. Though essentially identical in specs, The 400 watt machine has the thick aluminum finned heat sink and the 360 watt machine has the aluminum heat sink with the thin sheets. The 400 watt machine is definitely louder, but I'm not using either of them for critical audio work, so its just a preference thing on having them run a bit quieter.
    Both G4s are pretty loud. The noise bothers me a little, but what I really want to do is to replace what must be now pretty old delta fans with newer, quieter fans that will help extend the life of these 2nd hand computers that I plan to use for a number of years.
    I scoured the web and read many articles about MDD mods and fan replacements, but many of the articles date back to 2003 and most of the fans that people have used seem to be no longer produced or available (such as the panaflow model referenced on xlr8yourmac.com I ran into many dead links! Maybe that's because there are better fan options now?
    If anyone out there has replaced or upgraded their fans in a MDD recently, could you please reply and let me know...
    Where you got them
    What size and model number(s) for the fans
    Whether you noticed any improvement in noise/cooling
    I saw a recent post about replacing fans on an AGP Power Mac...
    http://discussions.apple.com/message.jspa?messageID=11628216#11628216
    Would these fans be the same? I'm guessing that the MDD wind tunnel might need more cooling than a G4 (AGP) right? SOme places mentioned that the main fans were 119x119x25, while others mentioned that hey were 120x120x25. Is 1mm going to make a difference? I'd prefer not to have to dremel them if I don't need to!
    Lastly, if you have a direct link to a reasonably priced fan that you'd recommend, I'd appreciate it greatly!
    Thanks for any help!
    Dave C

    Thanks Japamac!
    Thanks for your replies! Those look very good! So many to choose...
    Exactly the info I was looking for. I was checking out the panaflow (I was a bit overwhelmed by the number of choices on the 'Performance-pcs' website... if you were buying, which one of those 34 would you get? Assuming a budget of 20 bucks per 120mm fan...)
    But a followup question on the Panaflo model you linked to. In the many web articles I read I recall that one being well regarded. ,IF I buy that one, I have a few choices on tail options...
    3 pin
    4 pin
    4 pin male molex with separate 3 pin rpm connector
    Am I correct that if I opt for the last option I can get the fan to run at a medium rpm all the time and have it be less likely to ramp up under heavy loads?
    Lastly, will this possibly be a problem I might have, simiar to what was noted by a xlr8yourmac fan modder -->
    http://www.xlr8yourmac.com/systems/g4mirrored_drive_doors/noise_reduction/g4_ddr_noisereduction.html
    "(Updated comments added 7/9/2009)
    I have an important update to that G4 fan mod note I gave you.
    I noticed that the 120mm fan wasn't pushing as much air as I thought it should, and I realized it was because the 2-pin fan connector on the motherboard wasn't providing enough power. +(3 pin connectors typically are for adjustable/variable speeds. But if it's a constant speed fan then maybe the 2 pin wiring was using only 5V vs 12V? (higher voltage = higher rpm fan speed typically)-Mike)+ I put the 3-pin connector back on and used a 3 to 4 pin Molex adapter adapter to connect it to the 4-pin hard drive power cables -- voila! Lots more air. So... Following the directions in the older article exactly may NOT work depending on the fan you get. Also, using a 3 to 4 pin adapter is much easier than modifying the connector from 3 to 2 pins as indicated in the article."
    This was confusing because I thought that there was just a 3 wire lead to connect or splice, with the yellow wire probably just not being used.
    Your thoughts?
