Power wont turn on..battery led flash orange


Remove battery. Maybe faulty? Try another cord/charger with the EXACT same specs. Reseat the Memory Mods. has the AC jack been damaged by pulling on the cord? Try plug in and at the laptop's AC jack "wiggle" the AC jack plug. Any change?

!!!no reaction on plugging the ac adaptor.!!!


Sound like the LCD screen's inverter is causing an short/overload and the power adapter is shutting down (thermal cutout).
Remove the LCD screen and connect an external monitor, power up the external monitor first and the boot up the laptop. The video should automatically on the external monitor. If the display on the external monitor is OK then the fault could be the inverter which is located at the bottom of the LCD screen between the hinges.
LCD screens and Inverters for your laptop maybe available from this WEB site.www.lcdparts.net

HHello there,\r\n I have a very strange problem


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:
  1. 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. here the picture of the power jack:

Does the toshiba satellite a105-s4547 have a built in mic


Hi, As to my own surprise: no. This laptop doesn't have a built-in microphone, though it does have a microphone connection. You can buy a cheap mic and plug it into the mic jack.
Cheers, Ed

Toshiba Satellite A105 - S4547, screen goes black when using the battery (not plugged in)


check your control panel/video to ensure device driver is current. use driverguide.net.since when on battery no pic suggests that the battery life span is shortened. Recharge and check how long the battery level lasts when doing normal internet or document reviews. Video playing drains the battery at a high rate, when battery is already low, virtual memory tries to assist.

sounds like you have an intermittent problem with your AC adaptor or dc input jack. Does the light on the AC adaptor light up when you plug it in? If it does then your dc input jack may be faulty. If the light on the ac adaptor does not light then replace the ac adaptor. Good Luck!
