TOSHIBA ERROR CODE LED

Toshiba Laptop Error codes (Power flashing led) 东芝机器-蓝色板遇到好几个a10，都是闪灯，不知道怎么下手，google了一下，发现这个，希望对大家有所帮助我找到了自己板为40h，下一步还没找到，但总算有点希望了。

看电源灯闪烁，共8次，组合出一个16进制数，然后根据他在查下面的东西
灯闪1秒代表1
4 C: h& I3 ?) ?灯闪半秒代表0

1 L8 J# z7 y9 X# M我的8次为

' v/ f7 e# ]8 M2 b% N在转换为16进制数为40h
在查下面资料为

S3V voltage is not more than 3.14V when the computer is powered on or off.

粗略翻译为没有更多的3.14v电压在计算机开机和关机时。
这个s3v还不清楚是动态的3v还是静态的。

Hi Luciano, great discovery. Too bad that now Toshiba has denied access to those manuals, however those pages are still in Google's cache as today. Who knows how longer will they be? For those who will need this after us, I may say that I learned that if DC power led is flashing an error code, it means that there is a problem with the power supply. Now what problem? That will tell the code, but anyway most likely you are facing a dead motherboard.

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:

1 A5 ^5 ^  s; ]- ^- {8 ^- I' H6 KMake 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).

( Z9 M  [, V* eAfter checking the connection, perform the following:
