Hai assalamualaikum warahmatullahi

wabarakatuh berjumpa kembali dengan saya

Restu Febriana dan di video kali ini

saya mau menunjukkan permasalahan di

komputer dan disini untuk komputer nomor

9 yang ada masalah ya ada masalah mati

ya Jadi ini teman-teman bisa cek ya ini

kabel powernya sudah tersambung itu

untuk monitornya nih normal ya untuk

monitornya

Hai nah

Hai tetapi ini ada permasalahannya di

CPU ya Nah ini jika saya tekan tombol

power

Hai m cetakan Nah itu tidak ada respon

Ya ini yang harusnya si lampunya itu kan

menyala ya Nah di bagian ini

Hai itu kan harusnya menyala tapi eh di

komputer ini tidak nyala sama sekali ya

di lampu-lampunya itu Nah jika saya

tekan tombol

Hai ke tidak menyala

Hai dan untuk permasalahan seperti ini

Hai untuk komputer yang tidak menyala

sama sekali itu

Hai diakibatkan karena biasanya

diakibatkan karena power supply atau

Facebook Nah jadi untuk teman-teman yang

belajar menservis komputer dengan alat

yang sederhana ya tentunya

Ayo kita bisa membedakan permasalahan

antara kerusakan dari sebuah RAM

harddisk kemudian power supply dan

prosesor ya jika si komputer mati total

seperti ini

Hai itu salah satunya ya salah satu

permasalahannya itu bisa diakibatkan

karena power supply yang sudah mati

ataupun lemah ya tapi biasanya power

supply yang mati yang mengakibatkan sih

komputer ini tidak bisa menyala itu

karena pada saat kita menekan tombol

power atau sesuit power ini itu yang

seharusnya ada respon Ya dari power

supply ke motherboard dan disini

dikarenakan power supplynya yang tidak

bekerja maka si kompos ini Ati Ya

intinya seperti itu temen Jadi kalau

misalkan si komputer kalau kita tekan

tombol powernya itu tidak ada respon Ya

sebelum ke power supply kita bisa cek

dulu tentunya di bagian belakang nah nah

di untuk bagian belakang CPUnya itu kan

ada yang Powers naikan power supply Ya

ini yang

di blog ini ini adalah power supply jadi

power supply pun ada yang menggunakan

saklar ya saklar on-off disini yah di

bagian ini ataupun di bawah itu bisa

dicek tapi dahulu Apakah saklar power

supplynya sudah on atau belum gitu ya

kemudian ini sih kabel powernya juga di

cek juga Apakah ada listrik ya yang

mengalir ke power supply tidak enak jika

normal ya jika normal maka

Ayo kita bisa menyimpulkan bahwa power

supply lah yang Nah ini kan power supply

the bahwa power supply yang bermasalah

gitu jadi untuk permasalahan power

supply itu itu saya mendeteksinya jika

saya menekan tombol power

Hai itu si komputernya tidak menyala

sama sekali ya kan biasanya ada

indikatornya yang menyala sini ya

Lampunya itu menyala itu kalau normalnya

Nah itu biasanya kalau di bagian power

supply tapi kita juga bisa cek sih

bagian dalamnya ya di bagian kabel eh

kabel ini ya kabel front panel nya gitu

kan itu biasanya ada atau swh delete ada

reset gitu kan Nah itu juga bisa dicek

di bagian perkabelan nya yang ada di

dalam CPU ini tetapi sih Eh jika itu

sudah sudah tepat ya untuk penyambungan

jalurnya Nah itu biasanya memang yang

paling sering ini yang saya temukan itu

permasalahannya adalah di power

supplynya yang sudah mati kita jadi

kalau saya tekan tombol powernya itu

tidak ada respon sama sekali gitu Nah

itu diakibatkan karena power supply yang

mati

nah kemudian jika permasalahannya ada di

bagian RAM ya kalau orangnya yang

bermasalah itu temen-temen pada saat

menekan tombol power itu tetap menyala

si komputernya terpenjara tapi sisi

punya itu sudah menyala mati udah mati

nyala lagi mati lagi saat seperti itu

jadi mati nyala secara berulang kalau

permasalahannya di bagian RAM Kemudian

untuk di bagian RAM juga kalau misalkan

ada masalah CPO tetap menyala tetapi di

sininya ada tulisan no signal ya Atau

Mati hitam seperti ini dan kemudian

untuk blank hitam seperti ini Ya intinya

tidak ada tampilan sama sekali kita bisa

cek bagian ram-nya sudah bagian RAM juga

mungkin hardisk nya Baterai CMOS dan

prosesor yang kita cek kita Nah jadi

untuk membedakannya seperti itu kalau

permasalahannya di power supply maka ini

di bagian lampu indikatornya tidak

menyala sama sekali kalau di bagian RAM

cimos

sore itu biasanya menyala Ya tapi kalau

prosesor biasanya menyala tapi akan

langsung mati lagi gitu nah sama seperti

ram ya Jadi kalau permasalahnya

dieramkan kemudian batere CMOS itu

Hai CPUnya menyala tetapi nyala mati

secara berulang gitu ya kemudian kalau

batre cmosnya biasanya ini menyala biasa

tapi dianya nggak ada tampilan ke jadi

permasalahannya seperti itu oke

mudah-mudahan video ini bisa bermanfaat
