@Carlos Porto informei o modelo errado e o Inspiron 15-5547 A20

@Carlos Porto

pasta **bleep** onde ta essa pasta ? e para eu criar ?

@claudio cortez você esta afirmando que atualização e funciona pro caso da tela escura black ligth ou esta perguntando ?

@Carlos Porto essa bios que enviou serve para o modelo do meu notebook ?

Chegou a tela nova ficou do mesmo jeito testei com um cabo novo ficou do mesmo jeito também, alguma dica ?

@zazulak Beleza vou esperar ele parar novamente e posto aqui.

@zazulak Raspbian

Eu acesso o Raspberry remotamente pelo windows, mas o Raspberry e físico não e virtual não .

apenas o blynk para, consigo acessar o raspberry normalmente pelo vncviewer, o que seria a saída dmesg ?, poderia me explicar o que e ese estouro de memoria, sou iniciante ainda.

Boa noite, estou utilizando o Raspberry pi3 e montei um servidor chamado Blynk nele, porém o mesmo depois de alguns dia fica offline sozinho ai tenho que reiniciar o rasp para o servidor subir novamente, alguém esta passando por isso ?

A resina de dentista você só conseguira usar ela e deixar firme se possuir um fotopolimerizador.

2 opções que tenho para te indicar, se não tiver com pressa pode usar araldite , se tiver com pressa usa super bonder e depois joga sal encima que aonde tiver super bonder vira pedra, espero ter ajudado.

Qual o problema do tablet ?
