SOLVED.X1 Yoga Gen 1 wont power on

[Glitchy]

Hi, i have Lenovo ThinkPad X1 Yoga gen 1 and it wont power on.
It was low battery i powered it on and it died ... now no signs of life.
Did reset button but nothing.
If i plug in charger - battery charges.
Any ideas?
Actual battery does not look inflated.
Thank You.

SOLVED by unplugging cmos and battery then plugging battery back and powering on without cmos.
Kinda strange ... anyone knows why ?
