HP ZBook 14 G2 Mobile Workstation approx. 4 years old and out of warranty. HP Product Number - J8Z77ET Laptop boots into Windows 10 okay and O.S works fine. Mainboard will not charge any batteries - tried several batteries and chargers from working laptops, likely charging circuit fault. Also needs new bottom casing as corner has broken off. Please provide quote for repair and if it is worth repairing? Thanks, Dave
