The original LCD 1024x768 resolution is kinda low. This guide will show you how to fit HV121P01-100 or 101 into PowerBook G4 12".

Adım 1 LCD panel upgrade  ¶ 

Some HV121P01 are IBM/Lenovo/Thinkpad parts. Comes with Wacom Digitizer and front shield. Remove the Wacom Digitizer first. 1. remove the 4 philips screws in red circles. 2. use some thin object, like a knife, to separate the 2 double sided tapes in red rectangles from the white plastic back.

  • Some HV121P01 are IBM/Lenovo/Thinkpad parts. Comes with Wacom Digitizer and front shield. Remove the Wacom Digitizer first.

  • 1. remove the 4 philips screws in red circles.

  • 2. use some thin object, like a knife, to separate the 2 double sided tapes in red rectangles from the white plastic back.

  • Remove the 2 small metal parts in the red rectangles.

Adım 3  ¶ 

You need to extend the CCFL High Voltage cable, if it is not long enough to reach the inverter. You'd better get a electronics friend to help you. Should be very easy for him. If it's done wrong. Leakage or shock may happen.

  • Please measure and calculate the cable length precisely. There is not enough space for wires which are too long. In this pic, they ARE 25mm/1" longer than needed. Reworking them is painful.

Adım 4  ¶ 

Remove all the extra parts from the PCB, metal frame, and white plastic back. There are 9 of them. Use knife or other cutting tool to cut the plastic. Use cutting tool to cut PCB. Use Diamond impregnated files to cut the metal frame. It's very hard and stiff, you cannot cut it with knife or wire cutters. Or, you may hurt you tool or even the LCD GLASS!! That's a game over" Please be ALWAYS VERY CAREFUL and patient, DO NOT HURT the citcuit or the LCD glass (through the entire upgrade). Smooth all sharp metal edges. Should be 6 of them.

Adım 7  ¶ 

Drill four 1.5mm~2mm(1/16"~5/64") diameter, 3mm(1/8") deep holes at the left and right side of panel at the position corresponding to original LCD panel. Do NOT drill the glass!!. 2 will be drilled on metal and then plastic, 2 on plastic. As said before, the metal is very hard! use high quality drill and be patient and avoid overheating, or you'll burn your hand or the plastic and LCD glass.

  • In these pics, the upper LCD is the original one, the bottom one is HV121P01.

Adım 8  ¶ 

Remove the front shield, if any. It's positioned by double sided tape. Should not be very tight. But, still, be very careful about the LCD glass. if you have to break some thing, it should be the shield or tape.
