Battery InformationProper care will improve the performance and extend the life and cycle life of your battery. Please

follow these simple guidelines to get the best use out of your battery.

Power lossWhen not in use, a battery will gradually lose its power, this is normal. The rate of power loss

depends on the battery type and is approximately:

2% / Day for a Ni-MH Battery0.2% / Day for a Li-Ion Battery

Battery storageOutside the computer

If you are going to store a battery outside your computer for an extended period you must:

· Charge the battery to at least 40% capacity prior to storage.· Follow steps 1 through 3 approximately every 30 days:

1. Completely recharge the battery.2. Use the battery until it is fully discharged3. Recharge the battery to at least 40% capacity.

Inside the computerIf a fully charged battery is stored inside the computer and the battery is not used for more

than 30 days, you must follow these steps:

1. Completely recharge the battery.2. Use the battery until it is fully discharged3. Recharge the battery to 100% capacity.

(In this case it doesn’t matter whether or not the computer is being used)

Note: An empty battery will become damaged if stored too long and by following thesesteps the battery cycle life and the battery life will increase.

Battery TestingTesting a battery while its temperature remains high could possibly cause inaccurate

measurements, therefore we strongly recommend:

· Waiting 30 minutes before testing a battery that has just been fully charged.· Waiting at least 30 minutes before recharging a fully discharged battery.

Note: All battery testing should be done on a fully charged or fully discharged battery.

12

Battery alarmThe battery alarm is activated by a program and will sound when the battery power is low.

Note: If a fully discharged battery has been charged for less than 3 minutes, this program willnot be activated.

This happens when these 3 steps occur:

1. The computer is being used and the low battery alarm sounds.2. The AC adapter is connected to charge the battery while the computer continues to beused.3. The adapter is unplugged within the first 3 minutes of charging.

After this sequence of steps, the computer will eventually shutdown without the low batteryalarm sounding and you will lose any work you have entered and not saved.Therefore you should make sure that the AC adapter is firmly plugged into the computer whencharging the battery.

Installation ProceduresInstalling/Upgrading a processor

The notebook computer supports an Intel Pentium !!! processor of 500 MHz, 550 MHz, and 600MHz core frequencies.

Two CPU types are suitable for this machine, FC-PGA 370 and PPGA-370. The processors varyin height and depending on the processor type you may have to replace the 4 hex studs on themainboard.

The mainboard can support a FC-PGA370 type processor without adding the new hex studs.If you would like to use a PPGA-370 type processor you will need to add new hex studs which is

explained in this chapter.

Note: Remember to wear an antistatic wrist strap when adding or replacing the processor.

The 5 basic steps to Installing/Upgrading a processor are:

1) Remove the heat sink2) Remove the existing processor3) Replace the HEX STUDS (if you are installing a PPGA-370 type processor)4) Install a new processor5) Install the heat sink

28

Removing the heat sink

1) Unscrew and remove the CPU cover.2) Remove the four screws which hold the heat sink in place.3) Lift the heat sink out of the computer.

CPU cover

Heat sink

Note: If the thermal pad on the heatsink is broken, please change the thermal pad. Otherwise, it willcause CPU temperature too high.

29

Remove the existing processorAt this step you should have successfully removed the heat sink and you are now looking at the

CPU dock with processor.

Place the CPU tool (jig) on top ofthe CPU

Align the CPU tool (jig) over the CPU

Remove the Zif plug from the CLOSE side ofthe CPU dock.

The CPU dock with the Zif plug (lock) in place.

30

Place the screwdriver into the open slot on the CPUcaseHold the CPU tool (jig) in place and move the screw-driver in the towards the CPU. (this will unlock theCPU from its dock)

Remove the screwdriver and theCPU tool (jig) and gently lift theCPU out of the dock.

31

Hex studs

CPU (processor)

Replace the HEX STUDS ( if you are installing a PPGA-370 type processor)There are two heights of hex studs which can be used in the mainboard, 6.5 mm and 7.7 mm

(the 6.5 mm hex studs are gold and the 7.7 mm hex studs are black). If you are going to install a FC-PGA type processor you will need 6.5 mm hex studs. These hex studs come with the mainboard soyou don’t need to do this step.

If you want to install a PPGA-370 processor you will need 7.7 mm hex studs. To add or replacethe hex studs simply:

1) Unscrew the existing hex studs.2) Screw in the new correct size hex studs.

Caution: You must use 6.5 mm hex studs for the FC-PGA 370 processor and 7.7 mm hex studsfor the PPGA370 processor. Failure to do this will cause the processor to overheat.

32

Install a new processorNow you should be looking at an empty CPU dock and you should have changed the Hex studs

if it was necessary. To install a new processor simply follow these steps

Gently place the processor into the opened CPU dock andpress it into place

The empty CPU dock without aprocessor module.

Place the CPU tool (jig) on top ofthe CPU

Align the CPU tool (jig) with the CPU dock.

33

Remove the screwdriver and the CPU tool (jig)

Place the Zif plug (lock) on the CLOSE sideof the CPU dock.

The processor is now securely lockedinto the CPU dock.

Place the screwdriver into the close slot on the CPU case

Hold the CPU tool (jig) in place and move the screwdriverin towards the CPU. (this will lock the CPU securely inplace)

34

CPU cover

Heat sink

Install the heat sink

1) Place the heat sink on top of the Hex studs.2) Tighten the screws on the CLOSE side of the CPU dock first.

(this will prevent the dock from unlocking accidentally)3) Tighten the two screws on the OPEN side of the CPU dock.4) Make sure the Heat sink fan plug is properly installed5) Replace and screw in the CPU cover.

Updating the Flash ROM BIOSTo update the FLASH ROM BIOS you must do six things:

A: Download the BIOS update from the Kapok website.B: Create a bootable Floppy DiskC: Copy you BIOS files onto the bootable Floppy Disk.D: Set the DIP switches for BIOS Update (On position)E: Reboot your computer from the FDDF: Set the DIP Switches to the original position (Off position)G: Reboot from the HDD

A: Download the BIOS update from the website.

1)Using your web browser go to www.clevo.com.tw2)Choose Kapok from the home page3)Choose Support at the top of the Kapok page4)Select Download Drivers5)Select the model number of your computer and download the zip file to your computer.6)Unzip the file into a suitable directory.

B: Create a bootable Floppy Disk.

Through Windows 981)Insert a Floppy Disk into your FDD. (This disk will be overwritten and all information erased, somake sure it has no important data on it!)2)Go to My Computer or Windows Explorer.3)Highlight the Floppy Drive icon and click the left mouse button, a menu will appear.4)Select Format.5)In the “Format 3 ½ Floppy Drive” window select:

Format type = QuickOther options = Copy system files.

6)Press “Start”. (This will create a disk which you will use to boot your system and update yourBIOS)

Through DOS1) Insert a Floppy Disk into your FDD. (This disk will be overwritten and all information erased,

so make sure it has no important data on it!)2) At the DOS prompt type: Format A:/s

C: Copy your BIOS files onto the bootable Floppy Disk.Take the Unzipped BIOS files and copy them to the disk you just formatted.

36

4) Locate the DIP switches (Drawing 4-2).5) Set SW1-1 and SW1-2 to the ON position6) Reinsert the keyboard.

E: Reboot your computer from the FDD1)Insert the newly formatted disk with the BIOS files into your Floppy Drive.2)Restart your computer.

Note: When your system boots from the floppy disk it will automatically update the BIOS sinceone of the files your copied from the website is an executable file.

D: Set the DIP switches to ON1) Turn off the computer.2) Press the two keyboard latches to elevate the keyboard from its normal position. (refer toDrawing 4-1)3) Carefully lift the keyboard assembly out to expose the mainboard.

F: Set the DIP switches to the OFF position1) Turn off the computer.2) Press the two keyboard latches to elevate the keyboard from its normal position. (refer toDrawing 4-1)3) Carefully lift the keyboard assembly out to expose the mainboard.4) Locate the DIP switches (Drawing 4-2).5) Set SW1-1 and SW1-2 to the OFF position6) Reinsert the keyboard.

G: Reboot your computer from the HDDRemove the Floppy disk from the drive and restart your computer like you normally do.
