Boa,

A placa mãe do meu laptop não liga e quando conecto o carregador o led do laptop não acende mas no entanto há um ruído que se ouve na placa. Já limpei com benzina e já troquei a massa térmica e não acontece nada.

O que devo fazer agora?

HP ProBook 430 G2: Why power button and caps lock flashes once then turns off?

Wed, 22 Jul 2026 08:19:06 -0700

Good day, i have Hp Probook 430 G2 laptop. When i plug it in charging LED indicator lits but when i start it up the power and caps lock LEDs blink once and shuts down immediately together with charging LED indicator and the charging LED indicator turns on again. Already tried hard resetting it by disconnecting the battery and the charger and pressing the power button for couple of minutes. I tried different charger, recovery of BIOS using bootable flash disk but not responding also tried replacing and cleaning the RAM. What could be the possible problem? Thanks
