I have owned this laptop since 2007. In the meantime I did some repairs: I epoxied the broken hinge mounting point (common problem) and replaced the capacitors on the inverter module (also common problem). The casing is rubberized and it is becoming sticky, especially on the bottom. This is also a known problem of lots of devices from the 90s and 00s. Another thing I did, is I removed the old leaky cells out of the battery case, I did that in around 2012/2013. This saved the battery contacts and internals of laptop from corrosion. I included the schematics diagram of the how the cells were wired if someone wants to rebuild the battery at some point. The CMOS battery is still original (CR2032 cell) and it holds perfect time and date.

It came with MS-DOS 5.0, I later installed Windows 3.1 on it.

Charger is not included, but it will work fine on any 19V/20V laptop charger with a standard size barrel jack.

Original charger was 20V 1A

The laptop is fully working, but due to its age I can't provide any warranty for it.
