Hi everyone. lenovo e531 thinkpad edge cannot boot. the problem is it cant boot with battery only without connecting the charger, even though the battery is in good condition. Each time i press the power button an error e190 appears saying not enough power. When i connect the charger without battery it boots properly..please help
Try another charger, try another battery. If that does not work, then it's probably an issue with the charging circuit on the laptop, which is probably a motherboard swap. For that system you may think about just buying a working model of the same laptop and swap your drive into it, will probably be as cheap as buying parts to try.
