Masalah pada laptop toshiba Satelite L200

[Tiffani]

Aku ada problem dengan laptop ku, ketika dihubungkan ke listrik layar otomatis hang. terkadang juga timbul garis-garis hitam. bagaimana cara mengatasinya?
pernah ku coba cas laptop toshiba yang lain, tetapi tetap saja seperti itu.
kalau dicabut baterai dan di cas, laptopku langsung mati.
jadi sekarang kalau aku mau cas harus dalam keadaan sleep atau di shutdown dulu.
bagaimana sebaiknya yang aku lakukan?

I think it has something to do with the screen, so I advise you to check your laptop at a specialized service. Maybe the charger problem by not providing enough power.

check your charger with a meter ,Toshiba`s require 24 volts instead of the normal 19v that most laptops use ,if its kicking out around 24v then chargers good ,but Toshiba`s are well know for power issues especially the satellite & equium range

if its well under 24v then its under powering the laptop

i think the major problem is the "immediate stop", if we properly analyze this symptom we can get the solution. when we plug the AC/DC adapter to the laptop, it shuts down; so there are two major causes:

OVP protection problem (Over voltage protection)

the 19V of the adapter is not properly regulated; we need to replace te AC/AC adaptor
2. OCP protection problem (Over current protection) if the power jack is broken, it cause a bad metal to metal contact, in this case the transient current increase fastly, the power managment IC go to the standby mode; to protect all other device ( cpu, memory, graphic controller etc) , only two voltage are present: 3.3V always on and 5V always on, we can charge the battery. to solve the problem, we need to replace the power jack located on the laptop motherboard.
