Re: IBM Lenovo Thinkpad X61

Some laptops dont have a buzzer to produce error codes. If you plug a PS2 keyboard into the laptop (if you laptop has a PS2 connector) it should flash the NUM, CAPS, SCRL lights in a pattern, if you can find an error code chart for this laptop you might be able to locate whats wrong in the laptop. Could be bad RAM or even the CPU or NB.
