Well... from what I can figure out from the service manual, that sequence of blinks should indicate a battery pack problem where the, "Battery voltage is over the limit." To determine the error code, the sequences have to be converted from binary to hex. It seems your series of blinks would calculate to 10h. Though I'm not up on the very technical aspects of things. Neil just posted the URL to his copy of the 50/70 manual here: http://www.nbarnes.easynet.co.uk/libretto/li50_70ct.pdf So have a look in there. Here's what I copied from the pertinent section: ========================================================== 2.3 Power Supply Troubleshooting The power supply controls many functions and components. To determine if the power supply is functioning properly, start with Procedure 1 and continue with the other Procedures as instructed. The procedures described in this section are: Procedure 1: Power Status Check Procedure 2: Error Code Check Procedure 3: Connection Check Procedure 4: Replacement Check Procedure 1 Power Status Check The following icons indicate the power supply status: q Battery icon q DC IN icon The power supply controller displays the power supply status through the Battery and the DC IN icons as shown in the tables below. Table 2-1 Battery icon ====================== Battery icon Power supply status ============ =================== Lights orange Quick charge *1 Lights green Battery has a full charge and the AC adapter is connected Blinks orange The battery level becomes low while operating the computer on (even intervals) battery power*2 Doesn’t light Any condition other than those above. If the battery becomes too hot charging will stop and the battery icon will go out even if the AC adapter is connected *1 One of two battery levels becomes low. *2 AutoResume Off will be executed soon. Table 2-2 DC IN icon ==================== DC IN icon Power supply status ========== =================== Lights green DC power is being supplied from the AC adapter Blinks orange Power supply malfunction*3 Blinks green Stand-by state Doesn’t light Any condition other than those above *3 When the power supply controller detects a malfunction, the DC IN icon blinks and an error code is displayed. To check the power supply status, install a battery pack and connect an AC adapter. Check 1 If the DC IN icon flashes orange, go to Procedure 2. Check 2 If the DC IN icon does not light, go to Procedure 3. Check 3 If the Battery icon does not light orange or green, go to Procedure 4. CAUTION: Use only an AC adapter that is manufactured specifically for the Libretto 50CT/70CT. If you use a different AC adapter, the computer’s power supply may malfunction or a fuse on the system board may be blown. Procedure 2 Error Code Check ============================ If the microprocessor detects a malfunction, the DC IN icon blinks orange. The blink pattern indicates an error as shown below. [X] Start Off for 2 seconds [X] Error code (8 bit) "1": On for one second "0": On for half second Interval between data bits: Off for half second Error codes begin with the least significant digit. For example: Error code 12h (Error codes are given in hexadecimal) <----------------Read---------- On: ------| |-| |--| |-| |-| |--|_|-|_|-|_|-| Off: |____|0|_|1 |_|0|_|0|_|1 |_|0|_|0|_|0|___ Start^ -------------Order-----------> Bit 0 1 2 3 4 5 6 7 [X][X] Check 1 Convert the DC IN icon blink pattern into the hexadecimal error code and compare it to the tables below. [X] DC power supplied through AC adapter ====================================== Error code Meaning ========== ======= 01h AC adapter voltage is over the limit (16.5 V) [X] Battery pack ================ Error code Meaning ========== ======= 10h Battery voltage is over the limit 11h Battery charge current is over the limit 12h Battery discharge current is over the maximum allowed limit when there is no load 13h Battery voltage is under the limit [X] B5V,VCC output ================== Error code Meaning ========== ======= 20h VCC voltage is over the limit 21h VCC voltage is under the limit 22h VCC does not start up when power supply is turned on [X] B3V output ============== Error code Meaning ========== ======= 30h B3V voltage is over the limit 31h B3V voltage is under the limit 33h B3V does not start up when the power supply is turned on [X] Power supply microcontroller ================================ Error code Meaning ========== ======= 50h Firmware or program error [X] CPU environmental condition =============================== Error code Meaning ========== ======= 80h CPU temperature is outside the allowable range 88h CPU overheat (The CPU heat sensor has detected overheating and has automatically shut down) [X][X] Check 2 If error code 01h displays: [X] Be sure the AC adapter is firmly connected to the computer DC IN socket and to the power source. If these cables are connected correctly, go to the following step: [X] Replace the AC adapter with a new one. If the error still exists, go to Procedure 4. [X][X] Check 3 If error code 10h displays: [X] Make sure the battery pack is correctly installed in the computer. If it is, go to the following step: [X] Replace the battery pack with a new one. If the error still exists, go to Procedure 4. [X][X] Check 4 When 88h displays, it indicates that the CPU temperature is outside the allowable operating range. Do the following: [X] Leave the computer in an area that is about room temperature until the CPU’s internal temperature is within the allowable operating range. If the error still exists, go to Procedure 4. [X][X]Check 5 If error code 11h displays: [X] Go to Procedure 3. [X][X] Check 6 For any other error, go to Procedure 4. > ----- Original Message ----- > From: "Matt Hanson" <[EMAIL PROTECTED]> > To: "Libretto" <libretto@basiclink.com> > Sent: Thursday, February 10, 2005 7:47 AM > Subject: Re: [LIB] Charging problem on 50ct Error code > > > > Date: Wed, 9 Feb 2005 22:45:06 -0800 (PST) > > From: Matt Hanson <[EMAIL PROTECTED]> > > Subject: Re: [LIB] Charging problem on 50ct Error code > > > > Jürgen...
