Dead Compaq Armada 4210T Laptop
Hi,
My brother gave me his "dead" Compaq Armada 4210T laptop to repair. I normally service TVs and other stuff. With fully charged battery, absolutely nothing (no hard disk spin or floppy disk drive noise (with a boot floppy), no "beeps" or lights of any kind) happens when you turn it on. If I connect the external power (plugs into AC), the only thing that happens when you turn it on, 4 of five LEDs (power, caps lock, scroll lock, number lock) light up (the battery charging LED is off). However, you can't turn it off to make the LEDs go off unless you unplug the external power source. I opened the unit and found a tiny 5A fuse, but that tested good (not open). I examined circuits for bad solder joints. Also checked for loose connections of any kind. If you ever had this experience, please tell me what you did to fix it. Thanks in advance, Brad Before you type your password, credit card number, etc., be sure there is no active keystroke logger (spyware) in your PC. |
