Hi, I have a Latitude 7350 which comes in 2 parts - keyboard attached to tablet. Everything was working fine up until 2 nights ago, it was left plugged in in my office and when I went to boot it up yesterday morning absolutely nothing is happening.
When I power in to the keyboard I cannot even get the charging light in the top left corner of keyboard to light up. When I disconnect the tablet from the keyboard and power in directly to the power connector on the bottom of the tablet the LED on the top right beside the power button flashes Orange 4 times then white, it repeats this cycle - searching online I cannot find what this pattern means.
I have tried 2 power adapters which were definitely both working. As I look at it now the power status indicator on the tablet is solid white - should I maybe just leave it for a few hours before I start opening the cases up?
