Tried to install fresh copy of windows, but installation fails. Tried to replace memory chip in back, but didn't help. Tried to remove memory chip in back and run on built-in memory, won't boot. Ran bootable CD memory test, and it indicates built-in memory failure. Opened case to look for internal memory can see all motherboard components, but no obvious memory SODIMM inside.

You'll need to assign the CD drive (which should show up as USB devicein BIOS or setup) as first boot device, if capable on your model/Computer. After you press power button, you should see a menu or dialog that shows something like 'press F2' or 'Delete' to enter setup. Once in setup, you should navigate thru until you find boot options or something of that nature. Select 'Boot from CD' or ' USB Device'. You should now insert your XP CD into the drive, close the tray, then choose 'Save'. It should now let you boot from the XP CD. At the first screen, you should select 'R' for repair console. It will then ask you to select an installation, type a '1' and then press the 'Enter' key. Next line will ask you to type an Administrator password. If you have one, type it, then press Enter. If no password, just tap the Enter key. Now, at the prompt, type CHKDSK C: /r as in (C: a space /r). then tap the Enter. It shoild now attempt to repair your Windows 2000 installation. When it finishes, reboot, go back into Setup and change first boot device to hard drive. Select Save and reboot LT. Have fun!

That would be verry difficult to find. A service diagram of this model is imposible to be found, at least over the internet. However here are some tips you may find usefull. If you have acces to a multimeter or at least a current-voltage measuring device, try to turn on the laptop and measure the voltage on those pins where the resistor is missing. If you find something smaller then 10 volts you can try the following method.
Buy a 1 mega ohm resistor along with other smaller values like 100kilo ohm, 10kilo ohm, 1 kilo ohm, 100ohms, 10 ohms. These resistors don't need to be smd tipe, regular ones are good at least for this testing stage as long as you can solder them on the motherboard. Begin by using the larger values (1 mega ohm) and check to see if the problem is solved or something is different. Then decrease step by step checking each time how the problem evolves. When you reach to 1 kilo ohm, don't solder the resistence like before, instead mount an amper-meter in series (not parralel !!! ) with the resistor. Check to see how much current is passing through the resistor. If you find more then 100mA stop here, because by following this metod down to smaller values of that resistor you may damage the board if the current exceeds certain levels.
Try this simple tests and please notify my of the results. You may ask further questions if you need more details on this matter.

I couldnt get the boot menu to come up either, so i had to disable the hard drive from booting in the BIOS, so the system had no choice but to boot to the cd-rom. Worked great!

Connect your external CDROM to the laptop. I think it is a USB CDROM. Enter your bios setup. In the boot device section, try to find any option which says First Boot Device -> USB CDROM. If you can set this things then the computer will be able to boot from your external cdrom.

The Purpose behind the guide to you is emulate your exploit disk, instead of using the disk you use, you're storing the exploit files themselves to your memory card ie. you're ps2 menu and HDloader and any other .elf file. Then you're using the PS1 (retail) game to cause a buffer overflow exploit to load the elf files stored on your memory card, once this is done you get that modified PS2 menu. As I said in the first clairication request the swapping stuff doesn't pertain to you becuase you have a mod chip installed. The main purpose for you to use what i posted eariler was to give you your modified .elf PS2 menu back (cuz all of your tools were stored before on your exploit CD wich is a non retail burned copy) this gives you a way to boot up with things that are native to the PS2 (memory card and retail PS1 game) from the .elf PS2 menu you should be able to see better what is going on becuase you can access each disk type contents from that menu and should be able to launch the game (if your laser lense is functioning enough to read retail PS1 games) from the menu itself. Or if you've been using HDloader plop that .elf onto the memory card (explained on my site) and just navigate to that via the .elf PS2 menu and you'll at least be able to load games stored on your hard drive. This is just something you can use till you get your new PS2 chipped out.
Of coarse this is all speculation. If your PS2 can't even read retail PS1 games none of this will even work.
Sry I don't know anyone that does the chipped stations nemore. I'm sure someone on this site still does though.
