the power light on the side stays orange while the light on the power button blinks blue. I re-adjusted the battery but nothing. Please help me out someone!

Have you tried unplugging the power, removing the battery, pressing and holding the power button for 30 seconds? Sometimes a blinking power button means that it’s charging the battery. Sometimes blinking lights might even indicate a hardware failure (for instance, a failed battery, or damaged motherboard, or some other issue). You would have to reference your laptop’s user manual for more information on how to interpret these lights. You can just do some troubleshoot to see if any of these works for you. https://www.minitool.com/data-recovery/f

Your laptop may be in sleep mode and needs to “woken up”. Try turning it on again by hitting the power button.Press and hold the power button until the computer completely shuts off.Then try hitting the power button another time to see if it boots normally.
