Back in 2018, I purchased a refurbished CF-19 Mk5 in hopes of using it as a backup to my laptop and also a place to store important documents. As such, I rarely ever used it and never connected it to the internet. All was fine until a few months ago when I tried to turn it on. The light on the ac adapter shown green, battery was probably dead or low, but no lights appeared on the front of the toughbook... more puzzling, i went ahead an purchased a new battery and power cable, and didn't skimp on either. Still no lights on toughbook and reseting CMOS battery yielded no change. What are my options now?
