If your laptop has a modular battery, remove it, examine for any damage, or see if it needs cleansing around the contacts and inside the battery compartment.
Flicker is amplitude modulation of the light output that may be induced by voltage fluctuations in AC mains, residual ripples in the output current offered to the LED load, or драйвер для светодиодных светильников incompatible interplay between the dimming circuits and LED power supplies. Flicker may cause other temporal gentle artifacts (TLAs) which embrace stroboscopic impact (the misperception of motion) and phantom array (pattern appears when eyes transfer). Slide it back in and fasten the screws as soon as you’ve found out what sort of PSU you could have. How Do I Exchange My Energy Supply?
