IBM ThinkPad 340CSE

    Hello habrazhitel!

    Today I will lead my story about - IBM ThinkPad340cse,
    originally from the distant nineties.

    Caution, a lot of pictures!


    To my shame, I do not know the exact year of manufacture of this model.

    Characteristics of this laptop:
    Processor: IBM 486 SLC2 (66 Mhz!)
    RAM: 4 MB (expandable up to 12 MB)
    Hard disk: 200 MB
    Video chip from Cirrus logic
    There is a built-in floppy drive
    PCMCIA slot, port LPT, COM, VGA, PS / 2 for an external mouse
    Weight is about 4 kg, you can fight off in the gateway :) Comparison of the thickness of this laptop (Bottom) with an IBM ThinkPad 560X laptop (Top) Rear view, left to right: PS / 2, power, reset button, COM, PCMCIA , LPT, VGA

    Getting down to disassembly



    We remove the cover (There are no fastenings on the screen, it rests only on loops) One loop is broken, so the screen does not work (Someone tried to repair it by soldering.) By the way, the contrast and backlight controls are located on the screen. We do not need a screen, we remove it. The keyboard, as you should have noticed, is German. To remove it, you need to move it towards the loops until it clicks, and then raise it :) And it connects with three loops. Remove the keyboard. On the left is a floppy, on the right is a two hundred megabyte Toshiba hard drive, in the center there is a place for a battery. Well, remove them too :) Oops, the bios battery prevents the motherboard from being removed. We turn the case over and climb into the battery compartment, which is hidden next to the battery. Remove them.

    Finally, remove the motherboard (Together with the heat sink) Unscrew the heat sink. Here we see the processor (the one on which something gray is pasted) IBM 486, above it there is a video chip and on the bottom and sides there are 8 Toshiba RAM chips (Each chip is 512 KB) - only 4 MB Video chip Cirrus Logic CL-GD6245 And finally, the processor : IBM 486 SLC2 :)

    Instead of a conclusion


    The plans are to replace the cable and put in place of DOS 5.0, which now costs Windows 3.1.
    The battery is almost dead, holds no more than 30 minutes.
    The trackpoint is completely alive (For me, it was a shock when I found out that you can move the mouse with the help of the trackpoint in BIOS!)

    PS I apologize for the terrible photos :(

    UPD: I added photos of the BIOS. A
    duck, a thermometer, a screwdriver, a flag are all mouse cursors that By the way, not static, but animated - a duck when you move it flaps its wings, the screwdriver rotates, the flag flutters ...
