Here is a picture of the label for the riser card on the bottom corner of the motherboard. Doing a Google search reveals that the riser card is for the dial-up modem. |

In this picture the following is visible: Realtek 10/100 LAN controller chip, Texas Instruments PCMCIA Card controller chip, and the BIOS chip soldered onto the motherboard.

Here is a picture of the CPU/Northbridge/Southbridge with the old thermal compound cleaned off. The CPU is a Dothan-based Celeron M 370 (90nm) running at 1.5ghz (15 X 100mhz), mPGA-479M package, 1mb L2 cache, and a voltage of 1.245v (according to software). The chipset is a ATI Radeon Xpress 200M chipset composing of the SB400 Southbridge. I could not identify the Northbridge since the text is so tiny. |

Besides reapplying thermal paste such as Ceramique made by Arctic Silver, what else can be done? How about a little bit of overclocking fun? With the help of this technical guide and this photo guide I was able to overclock the Celeron M 370 CPU! The pin-mod forces 100 MHz bus socket 479 CPU's to run 133 MHz bus speed. With the pin-mod the new clock speed is now 15 X 133 MHz = 1995 MHz, a 500mhz overclock! Pictured are before and after screenshots of CPU-Z. As with any type of overclocking stability cannot be guaranteed so proceed at your own risk! My CPU was able to run Prime 95 Large FFT Test for 24 hours without any instability as pictured. If your CPU cannot run stable at the overclocked speeds, you WILL have to take apart your laptop and remove the wire. TIP: if you do perform the pin-mod, make sure the CPU is seated in the socket all the way. The pin-mod might slightly elevate the CPU from not being inserted into the CPU socket all the way because of the wire. If this happens you can push down on the green part of the CPU to force the CPU into the socket all the way. |
