4 year old Lenovo Flex4 1570 won't power on
My 4 year old Lenovo Flex4 1570 laptop won’t power on.
The battery led would blink amber lights. I tried unplugging the battery and holding the power button for 30 secs as suggested in some forums to get it out of sleep mode.
That didn’t work.
I figured then that the battery was done for and bought a new battery and replaced the old one. It’s charging now and I see blinking white lights indicating the new battery being charged. I tried powering on the laptop but I get the white power light to come on and then it goes off. Laptop does not power on.
Should the laptop power on when the new battery is charging? Or is it some other problem causing the laptop not to power on? CMOS battery?
I’ve seen some forums where the motherboard needs to be replaced. Not sure what to do at this point.
Thanks,

Ist dies eine gute Frage?

I unplugged the CMOS battery and the laptop battery and let it sit for a few minutes unplugged. Plugged them back in and the laptop restarted and was able to boot to Windows. Date and Time are off but otherwise I was able to get the laptop to work.
However, the battery won’t charge. This is a new battery bought from ifixit. So, is it possible that if the CMOS battery is dead it will prevent the main laptop battery from charging? I’ll try replacing the CMOS battery and see if that fixes this problem.
I haven’t seen a good logical explanation for how the CMOS battery can cause all these problems. My understanding is that the CMOS battery is used primarily to ensure the BIOS changes are preserved. Anyone have any thoughts on this?
