Reducing Heat Inside the PC
Reducing Heat Inside the PC
___________________________________________________
Heat buildup can cause problems for any computer. This document can help prevent heat related problems from occurring.
Some problems heat can cause include:
Games stop responding while being played.
Windows stops responding while being used.
When starting the computer, it sometimes stops at a black screen and does not open into Windows (Windows will usually stop responding when it does open).
Mouse and keyboard stop responding.
Computer unexpectedly restarts or provides a blue fault message (Windows Vista, XP).
or
Frequent Fatal Exception, Illegal Operation, or General Protection Fault error messages occur in several different software programs (Windows 95, 98, and Me).
These errors will not be predictable. If these errors occur only in one software program, the problem is probably related to that software program and is not heat related.
Causes of excessive heat:
Dust inside the computer. Dust problems are made worse if the computer is on a carpeted floor.
A new component, like a hard drive, has been added. The extra component causes the power supply to work harder and generate more heat. Extra heat also radiates off the new component and adds to the temperature inside the case.
Some cooling fans may slow down and wear over time, depending on the usage of the computer.
High ambient room temperature.
Before you begin
WARNING: Children and pets should not be in the area due to the hazard of electrical shock.
WARNING: The edges of metal panels can cut skin. Be careful not to slide skin along any interior metal edge of the computer.
CAUTION: This product contains components that are easily damaged by electrostatic discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a computer.
Make sure you have the following items:
Philips or slotted screwdrivers
Canned air (available from most computer repair and electronics stores)
Small flashlight
Safety goggles
Dust mask
Step 1: Testing the PC with the cover removed
Remove the side panel from the computer to see if the heat related problems go away. Doing so also prepares the computer for other procedures used in this article.
Turn off the computer and unplug the power cable.
Remove the side panel screws
Figure 1: Examples of panel screws
Remove the case panels or cover to expose the inside of the PC by sliding it off.
Plug in the power cable and turn on the computer.
CAUTION: Keep any items away from the internal area of the computer to avoid damaging the PC.
With the case cover removed, open a software program that is known to stop responding frequently to see if any problems still occur.
If the problems go away, excessive heat is probably building up inside the computer case. Use the steps in the rest of this document to help reduce the temperature inside the case.
If the problems do not go away, they are probably not being caused by heat. Refer to the Related Support section for further assistance.
Step 2: Verifying fans are operational
With the power on, look inside the computer and find the cooling fans. Look for the fans near vents, around the processor, and around the video card. You can use a flashlight to help find the fans but do not put anything inside the computer.
Figure 2: Fan locations
If a fan is not moving or is making a loud growling noise, turn off the computer and replace the fan. Do not use the computer when a fan is not working properly because the high heat can damage other important components.
Go to the next step after all fans are found to be working properly.
Step 3: Cleaning the computer
Dust may have built up around some of the internal components. Dust clogs the small air passages between metal surfaces, acting as a blanket to keep in heat. Use the steps below to remove dust:
WARNING: Wear safety goggles and a dust mask when using canned air to remove dust to protect eyes and nasal passages from dust.
Turn off the computer and disconnect the power cord.
Clean any exterior vents, especially around the power supply.
Figure 3: Power supply vent
Use canned air to blow the dust off the internal parts of the power supply.
If a small vacuum cleaner is available, use the suction end to remove dust from vent holes.
CAUTION: Do not use a vacuum cleaner to clean inside the PC. Doing so may damage the PC.
Remove dust from inside the computer. Use the canned air to clean off any dusty parts inside the computer.
After the computer has been cleaned, replace the case cover.
Plug in the power cord and turn on the computer. Use the computer as normal to see if any heat related problems still exist. If any problems continue, go to the next step.
Step 4: Placing the computer in a cooler room
A small difference in temperature may be all that is needed to prevent a component from failing. Move the computer to a cooler room in the house or office. If this is not an option, continue with the next step.
Step 5: Installing an extra fan
Case fans are available for purchase from most local computer supply stores. One type of fan that works well in home computers is a slot fan. These fans can be installed into a slot next to the video card. The hot air that surrounds the video card is drawn out through the slot fan lowering the air temperature inside the case.
Installation of the fan depends on the type of fan that is purchsed. After installing the fan according to its instructions, replace the case cover, plug in the power cord, and turn on the computer. Use the computer normally to see if the heat related problems go away.

This document pertains to HP 65xx and 66xx Desktop PCs that came with the following case:
Introduction
The following steps and illustrations provide you with a basic overview of what you need to do to take apart and reassemble your computer.
Before you begin
WARNING: To avoid damage to the system board or power supply, do not exceed a total of 120 watts power draw.
CAUTION: Do not overload the power supply by installing add-in boards that draw excessive current.
CAUTION: This product contains components that are easily damaged by Electrostatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a computer.
Shutting down Windows
Before working on the system, you must properly turn off Windows and turn off the power to the computer, monitor, and any other peripherals. Follow the procedure below to shut down Windows:
On the bottom left corner of the Windows main screen is the Start button. Click Start once.
Click Shut Down. The Shut Down Windows dialog box appears.
Select Shut Down and click OK.
Wait a few seconds until the "It’s now safe to turn off your computer" message appears. You can turn off the power to the computer by pressing and holding the power button on the front of the PC.
Removing the system cover
Observe all Safety and ESD precautions stated in the Warnings and Cautions as noted above.
Turn off all devices that are connected to the PC.
Turn off the power to the PC.
Identify and tag all cables. Disconnect the cables from the system. Be sure to disconnect the modem cable BEFORE disconnecting the power cord.
Remove the 3 screws from the back of the case (1 on each side near the bottom and at the center of the top) on the back of the unit.

From the rear of the system, pull back firmly on the cover to release it from the tabs on the frame, then lift the cover straight up and off the unit.
Removing the motherboard access panel
To open the panel without removing it
The right side of the computer, while facing the front of the system, is the Motherboard Access Panel. The motherboard is mounted to this panel and the panel must be opened slightly or removed to gain access to the right side of the inside case. To open the panel without removing it, follow the procedure below:
Remove the 4 screws that secure the Motherboard Access Panel to the case. Two are on the right side, and two are on the back panel.
Figure 2: Access panel screws
Grasp the opening near the front edge of the panel and open it away from the case.
Figure 3: Access panel
Pull panel out about 3 to 4 inches (7.62 to 10.16 centimeters) from the front edge of the case. You will now have access inside the case to remove drive bay screws on devices and the tabs for removing the drive bay filler bezel and the Front Panel locking tabs.
To completely remove the panel
To completely remove the Motherboard Access Panel, follow the procedure below:
Remove the 4 screws that secure the Motherboard Access Panel to the case. Two are on the right side, and two are on the back panel.
Grasp the opening near the front edge of the panel and pull it slightly away from the case. The panel will pivot around an interlocking hinge point on the back panel. Pull the panel out about 3 to 4 inches (7.62 to 10.16 centimeters) from the front edge of the case.

Figure 7: Slot for access panel
Close the access panel, making sure the 2 parts of the hinge remain interlocked. Stop when the panel is at about a 45-degree angle from the side of the chassis.
Reconnect all cables to the motherboard.
fully close the acecess panel.
Secure the access panel using 4 screws.
Removing the front panel
To remove the power switch and front panel LEDs, you will first need to remove the front panel. Before removing the front panel, you will need to remove the device bay cover and the filler panel, which is below the CD-ROM drive.
Remove the 4 screws that secure the Motherboard Access Panel to the chassis and pivot the panel out to a 45-degree angle.
Remove the device bay cover by pressing down gently on the depression at the very top center of the cover, just below the CD-ROM drive. This will cause the cover to pop off.
With the device bay cover removed, you will have access to the filler panel. Remove the filler panel by releasing its 2 plastic tabs, one on each side of the chassis.
The front panel can now be removed. The front panel is held in place by 6 tabs, 3 on each side on the inside of the chassis.
Depress the bottom tab on both sides at the same time and pull the panel away from the chassis slightly, preventing the tabs from snapping back in place.
Depress the middle tab on both sides at the same time and pull the panel away from the chassis slightly, preventing the tabs from snapping back in place.
Depress the top tab on both sides and pull the panel away from the chassis.
Replacing the front panel
To replace the front panel, reverse the procedure for removing the panel.
Position the 6 tabs on the front panel with the chassis slots and press the panel forward making sure all 6 tabs snap into position.
Replace the top and bottom filler panel as appropriate making sure the 4 tabs, 2 on each side, snap into place in the device cage.
Replace the device bay cover, if appropriate.
Troubleshooting Power and Battery Problems
Troubleshooting Power and Battery Problems
___________________________________________________
In this document:
If the computer turns off immediately after it turns on
If the computer keeps beeping
If the battery doesn't charge
If a secondary battery doesn't charge
If the computer has a short operating time
If the Time Remaining for the battery is not correct
If the computer doesn't suspend to Standby mode as expected
If the computer doesn’t automatically hibernate as expected
If the computer turns off immediately after it turns on
Battery power is probably extremely low. Plug in the AC adapter or insert a charged battery.
If the computer keeps beeping
The computer beeps for 15 seconds when battery power is low. Save work, shut down Windows immediately, and insert a charged battery or plug in the AC adapter.
If the battery doesn't charge
Make sure the AC adapter is fully plugged into the power source and the computer, and that the light on the adapter is on.
If using a power strip, remove the AC adapter from the power strip and plug it directly into a wall outlet.
Make sure the battery is fully installed and locked in place.
Move the computer away from any nearby heat source. Unplug the AC adapter and allow the battery to cool down. If the battery gets too hot, it will not charge properly.
If available, try another battery and AC adapter.
If a secondary battery doesn't charge
The computer’s secondary battery won't charge until the main battery is fully charged.
Make sure the AC adapter is fully plugged into the power source and the computer, and that the light on the adapter is on.
Make sure the secondary battery is correctly installed and locked in place.
If the computer has a short operating time
Try conserving power using any of the suggestions listed below:
Plug in the AC adapter, especially while using a drive in the module bay or any external connections such as a PC Card or a modem.
Set the display brightness to the lowest comfortable level (Fn+F1).
Put the computer in Standby mode whenever it is not being used for a short while: press the blue sleep button for approximately one second or click Start, (Windows 95) or , Shut Down, (Windows 98 and 2000).
Put the computer in Hibernate mode whenever there is a need to save the current session but the computer will not be used for several hours. To do this press Fn+F12.
Set the automatic timeout settings to emphasize saving power. If the computer has a dual-speed processor, use the lower speed on battery power (the default settings conserve battery power).
If using an I/O PC Card, a PC Card having an external connection such as a network card, remove it when it is not being used. Some I/O cards use significant power even while they're inactive.
If working with an application that uses the serial port or an I/O PC Card, exit the application when finished using it.
Install a secondary battery.
If the main battery is rated at 11.1 volts (check its label), purchase a replacement main battery, which is rated at 14.8 volts.
If running an application that has an automatic save feature (such as MS Word), disable this feature or increase the specified save time to reduce hard disk access.
If the operating time has gradually become shorter and the battery is more than a year or two old, the battery may need replacing.
Heavy modem use can affect battery operating time.
If the Time Remaining for the battery is not correct
The Time Remaining is an estimate, not a precise value, and is based on the rate at which the computer is using power at the moment. This value therefore depends on the current task, and assumes that the power will continue to be used at the same rate until the battery runs out. So, check the Time Remaining while the computer is performing a task requiring a good deal of power (such as reading from a CD or DVD), the value will probably show less time remaining than it really has, since you will probably later switch to tasks that require less power.
If the computer doesn't suspend to Standby mode as expected
If using a connection to another computer, the computer won’t suspend if the connection is active.
If the computer is performing an operation, it normally waits for the operation to finish before suspending.
For Windows 95, if a CD-ROM drive is present, make sure auto insert notification is disabled (the default factory setting). This is not required for Windows 98 or 2000.
In Windows 95 or 98, view the CD-ROM drive properties in Device Manager.
If the computer doesn’t automatically hibernate as expected
For Windows 2000, make sure hibernate support is enabled. From Control Panel, open Power, then click the Hibernate tab.
Also, check the Power Schemes tab. Make sure the Hibernate timeouts for both AC power and battery power are not set to Never.
For Windows 95 or 98, check the Hibernate timeout in BIOS Setup.
