Spin 3 SP314 series won't power up; charge light blinks orange once - help!
I have a Spin 3 (SP314 series) that has recently stopped powering up for no apparent reason. Nothing happens -- no keyboard backlight, no screen display -- when I press the power button, whether for a moment or when I hold it down for 5-10 seconds. When I disconnect and reconnect the power supply, there is a 3 second pause and then the charging light blinks orange once and then stays off.
By way of troubleshooting, I've checked my power supply and it is delivering 19V. I've tried resetting the battery by inserting a pin into the reset hole on the bottom of the machine, holding it down for 5-10 seconds, releasing it, and reconnecting power, but I still get a single orange blink and nothing else.
Can anyone diagnose the problem and suggest a fix? I really enjoy using this machine and hope it's not gone for good.
Thanks in advance for any help you can offer!
