Take a look:
Power Status Check
The following LEDs indicate the power supply status:
q Battery LED
q DC IN LED
The power supply controller displays the power supply status through the Battery and the DC IN LEDs as listed in the tables below.
Table 2-1 Battery LED
Battery LED Power supply status
Lights orange Quick charge.
Lights green Battery is fully charged and AC adapter is connected
Blinks orange (even intervals) The battery level becomes low while operating the computer on battery power.*1
Flashes orange The power switch is pressed on when the battery level is low.*2
Doesn't light Any condition other than those above.*1 Low Battery Hibernation will be executed soon.
*2 Low Battery Hibernation has already been executed.
Table 2-2 DC IN LED
DC IN LED Power supply status
Lights green DC power is being supplied from the AC adapter.
Blinks orange Power supply malfunction*3
Doesn't light Any condition other than those above.

When the power supply controller detects a malfunction, the DC IN LED blinks and an error code is displayed.
-------------------
Error Code Check
If the power supply microprocessor detects a malfunction, the DC IN LED blinks orange. The blink pattern indicates an error as shown below.

---------------------
In the case of error code 10h or 12h:
Make sure the AC adaptor cord and AC power cord are firmly plugged into the DC IN 15 V socket and wall outlet. If the cables are connected correctly, connect a new AC adaptor and/or AC power cord, if necessary.
In the case of error code 2Xh:
Make sure the battery pack is correctly installed in the computer. If the battery pack is correctly installed, replace the battery pack with a new one.
If the error still exists, the system board or the battery board may be disconnected or damaged. Disassemble the computer and check the connection between the AC adaptor and the system board and connection between the system board and the battery board (if there is one, in my case it was integrated to ths system board).
After checking the connection, perform the following:
Check 1
Replace the AC adaptor with a new one. If the AC adaptor is still not functioning properly, perform Check 2.
Check 2
Use a multimeter to make sure that the F8800 fuse on the System board is not blown. If the fuse is not blown, go to Check 3. If the fuse is blown, go to Check 6.
Check 3
Use a multimeter to make sure that the F1000 fuse on the Battery board is not blown. If the fuse is not blown, go to Check 4. If the fuse is blown, replace the Battery board with a new one following the instructions in Chapter 4.
Check 4
Make sure that the Battery board cables are firmly connected to PJ8820 and PJ8821 on the System board and to PJ1000 and PJ1001 on the battery board. If they are connected firmly, go to Check 5.
Check 5
The Battery board or System board may be damaged. Replace it with a new one following the instructions in Chapter 4.
I hope this helps many people with the troubleshooting. Details may vary as models vary, but most if it is the same for every Toshiba

you may have a faulty motherboard connection, but try connecting the power adapter in without the battery and see if it runs, then replace the battery back in the compartment.

if the check toshiba power saver ( start-- control panel--toshiba power saver, see if any settings refer to make the system standby after 1 minute.. I think you will find setting refer to that.

Motherboard repairs are often poorly done and they are expensive except for the simplest jobs like replacing the DC jack. And new motherboards are also generally very expensive. And cheap way out of this is buying a used battery charger or a used working motherboard. eBay is usually the best place to start. Good luck!

you will need to find out what BIOS chip is on the mobo...
hope this helps you out, when mine did it, it was much easier than this i found a bad connection at the power plug.

I have the same problem with my toshiba. I am convinced that is the motherboard. I am still trying to find a solution or a way to connect the battery direct to a dc source but not sure how that will work out. I am thinking that there must be a sort of AC power controller on capacitor that can be changed.....
symbol just to the right of the Start button. This allows all open windows to be suspended properly, with current data saved. When you startup the next morning, your open programs will still be running in the background. Clicking on your logon will have your right back where you left off.
, click and leave the computer alone, because it will be in the process of installing important updates before shutting down.595 views
