• Remove the battery and the AC adapter from the WinBook. This is a must. Turn the Unit upside down and make sure the floppy drive is facing to the right and is closest to you. You will need a small #1 Phillips screwdriver.
• First remove the small Phillips screw locking the floppy drive locking tab (See picture below). Slide the tab away from the floppy drive and while holding it in this position slide the floppy drive out and away from the WinBook.

• You should now see the Hard Drive setting in it's retainer and the two screws holding it in place (see picture below). Remove these two screws and set them aside. At this point we need to slide the hard drive to the right until the 40 gold pins are completely free of the socket connector.

WARNING: Slide, do not lift he HDD because lifting will bend the pins

• After the Drive is out you will see that the hard drive is attached to the retainer with three more screws. Remove these screws and the hard drive will be freed from the retainer.
• Insert the new hard drive back into the retainer making sure to orient it as it was when removed. When looking at the pins head on the screw tabs will be on the left side of the drive. Reinstall the three screws making sure no to over-tighten them.
• Lay the drive assembly back into the cavity of the WinBook, do not try to insert the pins first, failure to do this will bend or break the pins. Once the drive in laying in the cavity, slide it to the left while lining up the 40 pins into the appropriate socket. It should line right up to begin with and may require a little force to make sure the pins are inserted fully.
• At this time the two hold down screws should be lined up perfectly with the screw holes. It is normal that the screw all the way to the left has the threads starting immediately, while the screw all the way to the right will seem to fall into a hole and will only be retained by a few threads.
• Lay the floppy drive back into it's cavity and slide it firmly to the left until it clicks into place and the retaining latch locks it into place Replace the latch retainment screw. At this point the replacement is done and the unit is ready to have the battery reinserted and the ac power connected if desired.
• If this hard drive is factory mastered the unit is ready to boot up into Windows 98. If this is a blank hard drive, then you will need to configure the hard drive to accept your chosen Operating System.
