Toshiba Satellite Laptop Power Failure (A105-S1013 System Unit)

I own a laptop computer, Toshiba Satellite A105-S1013 System Unit. I experienced a complete power failure while watching a DVD movie around 1 hour into the movie. My laptop was plugged into the AC adapter at the time because the battery was holding a charge for less than 30 minutes. My laptop is almost 2 years old so I assumed that the battery was just almost worn out. It was only while reading forum posts in an effort to determine the potential cause of my current power failure that I realized a BIOS upgrade is available on the Toshiba website that may have potentially fixed the battery problem. Could that have something to do with the power failure? Anyway, I am sure that my AC adapter is working properly because I took it to the shop and they tested it. I read that some Toshiba Satellites have had problems with the power connectors losing their contact with the motherboard (MB) via worn solder connections. I took my laptop apart to see if this might be the problem. The power connector on my laptop is fitted in a slot on the back of the laptop case and connected to the MB via a small power cord that is plugged into the MB. Upon a visual inspection this connection seemed okay. I did not disconnect it to examine it further. Should I disconnect it and clean the contacts and try reconnecting it? Should I then solder it? Should I purchase a new power connector and try replacing the original one? When the laptop is plugged into the AC adapter no power indicator lights come on. I have tried this with the battery in and with the battery removed. As suggested in a previous post, I have also removed the battery and disconnected the laptop from the AC adapter, pressed the power button for 20 seconds, plugged the laptop back in to the AC adapter and then tried to turn it on again – with no result and still no power indicator light coming on. Could my problem be a RAM chip that has gone bad? Any other suggestions would be greatly appreciated before I must resort to taking the laptop to a repair shop.

Respectfully submitted,

Max

This relates to A100-756 Sattelite, just suddenly died and when AC connected the battery amber light flashes 11 times and that it, no power, no noise just battery amber light. Remove the AC Adaptor and nothing - No amber light - so please can you advise what I should do, warranty has expired, bought this 17 months ago and Toshiba technical support want to colect from my work address and claim they will find the problem, quote me and fix if acceptable but I am not sure if this is the best thing or should I give to a local Lap top guy who can fix?

    i am having the very same exact problem

  • woaikonglong Dec 11, 2008

    I have the same problem and it is not the first time, either. The first time I took it to geek squad and was told that the motherboard had slipped and it would need to be replaced and that the cost would be ~$600 dollars. Since this is the cost of a new computer, I wanted a second opinion and took it to a Toshiba support center three hours away, turns out the powercord was failing which killed the battery. Now I am having the same trouble and don't know which to assume, but if you get one answer, and don't like the price, seek a second opinion!

How handy are you with a digital multimeter? If the laptop is still disassembled, find the solder connections on the motherboard where the mini power cable enters the board from the jack. Plug the AC adapter in. Check to make sure you have the proper DC voltage at those points (should be about 19V, although the AC adapter should say what it's DC output is).

If you don't get any DC voltage (or too low), check the DC plug of the AC adapter. The inside of the plug should be + and the outside should be -. If you are getting voltage there, but not the motherboard, chances are it's the jack or the mini power cable on the motherboard. These can be replaced, it just depends on how confident you are about doing it yourself :).

Toshiba a105 on start up screen is red, then goes black


The Toshiba A105 notebook computer is made for mobile computer users who need optimal processing power. The LCD screen is a 15.4 diagonal widescreen with TruBright technology. The laptop has a fast hard drive access rate that is in the 3ms range for the paging and access of data. There are problems that can occur with the Satellite A105 that can be solved by knowing what to look for when troubleshooting the system.

Black Screen Problem Black screen problems can occur when the Satellite A105 backlight is burned out or the inverter is not working correctly. The backlight can be replaced with a new LCD bulb manufactured for LCD screens. The inverter is a housing unit that controls the voltage to the LCD screen. The inverter must be replaced by a compatible A105 Satellite inverter unit. Power Problems b> During the power-up phase of the laptop, the Satellite A105 will quickly turn off without signing into the Windows Operating Screen. The problem can be due to a faulty power adapter that is not supplying the right amount of voltage to the system board. You can also check to see if the unit that houses the power plug is loose, which also indicates lack of voltage or electricity going to the board for power up operations. Hardware Conflict Problems b> Hardware conflicts can cause system errors or "freezes" by loading a new hardware component into the same hardware I/O address. The Satellite A105 has designated input/output addresses for peripheral devices, such as hard drives, video drivers and other hardware functions. To solve hardware conflicts, use the Control Panel "Hardware" device function to see which hardware I/O addresses is not being used. b> Audio Not Working Correctly b> Loading a new audio program can cause the audio codec for the Satellite A105 not to produce sound. The audio codec can be restored by loading the "restore system disk" for the A105 laptop. The restore menu provides options on certain components that you want to restore. If you pick the option for audio, the program will restore the audio to its factory settings. b> On-board LAN Switch Not Working b> The Satellite A105 is automatically configured to detect T Base 10/100 Ethernet networks. If the laptop does not recognize the on-board LAN switch, check the system setup to examine if the LAN switch is on. If so, a firmware update may be needed to upgrade the BIOS.
