Laptop Compaq Presario 2700 Keyboard & Mousepad lost at all

I had a problem with the heat sink of my Compaq Presario 2700. Heat sink detached from motherboard. Well I just got 4 screws, push them from outside thru the plastic case under the motherboard and thru some ALREADY made holes to attach them to the heat sink. (Just in case... I didn´t made any holes or breaked or pushed the motherboard) Well at the end PROBLEM SOLVED. The heat sink works great, smoothly and no noise at all.

BUT NOW my keyboard and mousepad doesn´t work AT ALL. Drivers are OK, No problems reported at the Device Manager List. For Windows XP SP2 everythings is OK... BUT the fact is that my keyboard and mousepad doesn´t work at all. Not even from the very very start. I am not even posible to enter BIOS. The only way I can work with the laptop is to plug a USB external Keyboard & Mouse. There was when I discovered that when entering the BIOS (with the external USB keyboard & Mousepad) the BIOS post an ERROR 0222: Keyboard Error. Can anyone help me with this problem please ???

    Same problem. Fixed the heat sink problem, but then no pointer or keyboard functionality. I don't see how it could be related to a third layer in the MB as it was a metal post that went through the MB and was soldered in place.

    I am anxious to know if the plastic screw thing worked.

I read somwhere that most motherboards have a third layer of conductors laminated in the middle of board.It could be possible that you are shorting out something there. Take the screws out and try it without the heatsink for a minute or so. Most big DUI stores sell plastic screws in their hardware areas. These will work no problem.

INSIDE A COMPUTER OR THE HEAT SINK FOR YOUR COMPAQ COMPUTER?

The "CPU" or central processing unit, otherwise known simply as "the processor," is the primary "brain" of the computer. Processors are very finely engineered components that are not repairable. But replacing a failed processor is an option for the owner of any model Compaq Presario desktop computer. Just check with HP/Compaq for the correct and speed of processor for your motherboard before purchasing a replacement.

Turn off the computer and disconnect all cables. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Remove the cover. Lay the computer down flat. If there is a plastic hood covering an exhaust fan, remove it by pressing in on the indicated release tabs. Examine the processor assembly. The processor is a square chip that is covered by a metal heat sink with fins. A fan will often be mounted on top of the heat sink; unplug its connection to the motherboard. Two clips usually secure the heat sink assembly to the top of the processor. Gently press down and slightly away on the flat end of a clip to release it. Avoid using a screwdriver to release a clip; a slip could scratch the motherboard. Release the clips and gently remove the assembly. The heat sink should separate, leaving the processor behind in the chip holder. Clean the bottom of the heat sink. Use a paper towel and a dab of solvent cleaner to remove the old thermal paste. Set the clean heat sink aside. Lift up the lever to unlock the old processor and remove it from the pin mount. Insert the new processor chip. Align the pins on the processor to the "cut off corner" or dot on the pin mount. The processor should drop into the pin holes easily. If the processor won't drop in easily, check the pin alignment. Once the processor is inserted correctly, pull down the lever to lock in the chip. Apply thermal paste to the bottom of the heat sink. Apply enough paste to cover the area of the small gray rectangle on top of the processor. Apply the paste with a spreader made from a piece of flexible plastic. Spread the paste evenly to a thickness of two sheets of paper. Check the heat sink mounting alignment and lower the heat sink onto the top of the processor. Reinstall the mounting clips. Reattach the heat sink fan to the motherboard if necessary. Plug in the computer and monitor and boot. If the machine won't boot or it emits warning "beeps," unplug the power and monitor, and troubleshoot your work until the computer boots successfully. Shut down again and replace the exhaust fan hood. Close up the computer and reboot. Hope this helps.

I want to get to the motherboard. how many screws are there?


1 Wear an antistatic wrist strap before you start dismantling the notebook. Doing so will prevent static electricity from damaging internal components.
2 Shut down the notebook, and remove its AC power cord and battery. Turn the laptop over and remove all marked screws from the bottom. Raise the plastic shells covering the hard drive, memory (RAM) and wireless card slots, and uninstall the components by lifting off the base. You may have to release locking clips to free the RAM module from its slot.
3 Turn the laptop around and detach the keyboard panel. Using a flat-head screwdriver, push inward on the four small latches holding the keyboard in place to disengage them. Lift the keyboard to remove it, and disconnect its flex cable. Remove the five screws from the exposed landing. Do not undo the screws securing the heat sink and CD-ROM drive.
4 Split the notebook casing open. Insert a pointy or flat-tipped implement between the top and bottom parts of the casing, and maneuver to detach the locking mechanisms holding the two parts together. Work your way all around the perimeter to detach and remove the top casing. Do not apply too much force, or you may break the plastic parts.
5 Remove the hinge covers holding the LCD panel. Unscrew the two plastic hinges to loosen the display assembly and its enclosed LCD screen. Locate and pry open the CMOS battery---a flat, circular component resembling a watch battery---from the motherboard. Disconnect the LCD cables, and detach the panel from the laptop by lifting it up from its position.
6 Undo all securing screws from the chipset and heat sink. Remove the components by gently raising, checking to ensure that you've disengaged all attachments. Remove the CD-ROM drive by unscrewing its attachment and detaching it from the notebook. With the optical drive off, disconnect the speaker's connecting wires and remove the speaker assembly.
7 Unscrew all points of attachment to release the motherboard from the notebook's chassis. Locate and undo all locking mechanisms, such as clips or hooks, to free the motherboard. Remove the plastic inserts for the modem, as well as the PCMCIA and SD card slots, and detach the motherboard. Move the board around a little to release it, and lift it off the notebook.

My old heat sink and fan have screw in attatchments and the new on has the plastic pop in and 1/4 turns. Help?


Your old heat sink and fan probably works just as as good or better than that stock Intel fan and heat sink. If your computer case does not allow access to the rear of the motherboard you are going to have to remove the motherboard to pull the back plate that was used to attach your old heat sink and fan. To install the Intel fan turn the pins until the screwdriver slot is perpendicular to the fan shroud (the tip of the arrow is furthest out), then push in any 2 opposite sides at the same time into the motherboard. You will here them click in. Repeat for the other 2 pins.

My Compaq Presario F730US keeps overheating the fan does not run properly what docking station do you recommend me to buy


I would recommend cleaning out the vents and geatsink grills with compressed air. I would then remove the heatsink unnit and replace the thermal grease on the heatsink and processor. Most laptops do not need any additional cooling if thier heatsinks are free of dirt, dust and debris. The compressed air can be bought at office supply chains. Just use short bursts of air and clean all the compartments including the cd tray. Just make sure to power down the laptop first and remove the battery.

Heat sink fell off processor


Go to your local Staple,Radio Shack or Best Buy and get a new heat sink and fan assembly, if you are lucky it will thread through the motherboard so you can reset it onto the processor chip. DO NOT PUT SUPERGLUE ON THE PROCESSOR.

I was adding a 512MB card to a Compaq Presario that has an ASUS K8S-LA (or Compaq motherboard: Salmon-GL6E) and discovered what looks like a heat sync loose inside the case. I can see where is was...


The ASUS K8S-LA main board has a variety of chips on it, however only the CPU is large enough to justify a dedicated heat sink.

The most likely location that your rogue heat sink is came from is your video card's processor. I'm lead to believe this for 2 reasons- 1) you say that the CPU heat sink is still in place, and it is the only heat sink on the main board, and 2) the location you described as to where you found the heat sink would be consistant with it falling off the video card (located in the AGP slot, directly below the cpu with the external ports facing left).

Below is a link on the HP website to the layout / photos of your main board which were referenced in this solution

This is actually very serious if it is the case as it could lead to rapid failure of your video card (or whatever card it goes to if that is the not the location). There are several guides available on the internet for "cleaning" heat sinks which will serve your purpose of reinstalling yours once you find the location.

Hope this information was helpful, please don't forget to rate my solution.
