Re: how to dissassembled IBM thinkpad 570
The keyboard is held by two screws on the bottom of the machine, then you just need to work it up ay one side and off. I've had a few that the keyboard was stuck, and had to pull a little harder to get it off. When separating the plastics, there are a few hidden screws under black sticky pads, 4 at the front of the machine that I can think of right off hand, make sure you get these. Once you get the keyboard off, just take your time and be sure to remove all visible screws. Here's a link to some IBM service manuals. Couldn't find one for the 570, but the T series have the same basic design. Look over the manuals, they should be able to give you a better idea of hoe they come apart.

You can find the Hardware and Maintenance Manual here, which gives all the details on removing the keyboard. But this model ships with the standard memory under the keyboard (in a single DIMM socket). Optional memory (again, just a single available socket) is installed from the bottom of the computer. You don't need to remove the keyboard, just loosen one screw that secures the cover over the memory socket. Page 71 in the manual shows the location.
Hi You'll probably need to take it to a reputable repair person or check my website www.micromend.com. The reason is that a program such as ERD Commander needs to be used to eliminate the password and then to restore the laptop is a 10 cd set with Windows and all the drivers. Good luck
If you have forgotten your BIOS or system password, there are no software tricks or magical gimmicks that will get the password cleared. Laptops are different in that they are designed to not work with “backdoors” etc. for security reasons. There is one true way that works most of the time and that is hardware.
The Cmos (RTC) battery that is mounted on the motherboard in most cases holds the key, if your motherboard has the battery that is connected to the motherboard by using a two wire socket that plugs into the MOBO, then here is the procedure.
On the motherboard where the battery plugs into, you will see two pins sticking straight up, these engage the plug on the battery side. These two pins have to be “shorted” and then the motherboard powered up for approx. 30 seconds, then power down the system and replace the Cmos battery and reboot. Your password problem should be cleared up. The best way to “short” the pins is get another cmos battery and cut the wires from the battery part, bare the ends and twist together, this will short the pins. Make sure you tape the connection good on the jumper you just made….don’t want to touch anything else with powered up bare wires. Good luck.
The IBM error 301 POST code means the keyboard is not responding correctly.
You could have a stuck key, or the keyboard cable is faulty and not making proper electrical contact.
You could have a faulty keyboard controller.
You may have a faulty keyboard which may had some fluid spilt on the keys.
Try clean and reconnect the keyboard cable.
If this doesn't work try connecting an USB keyboard and see if this keyboard functions correctly.
If none of these work you have a motherboard problem. The Thinkpad 600 is a very old laptop and it would not be worth fixing. I suggest putting your money towards a new laptop.
Check the connections and the drive settings (jumpers) to make sure its set to "Master, Stand alone". The IBM PC's autodetect's the HDD installed so if it doesn't read the HDD, there is a hardware problem. Maybe is the Thinkpad interface faulty and the HDD you replaced is fine.
