I got a new battery from the supplier. All is ok, no flashing orange led. The battery gets charged. I'am glad, but the error code Battery voltage is over the limit. makes no sense at all, when given to a new, but defect battery. Thanks for helping Jürgen Schöll

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 Doesnt 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 iconPower supply status ===== Lights green DC power is being supplied from the AC adapter Blinks orange Power supply malfunction*3 Blinks green Stand-by state Doesnt 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 computers 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 12 3 45 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 == === 10hBattery voltage is over the limit 11hBattery charge current is over the limit 12hBattery discharge current is over the maximum allowed limit when there is no load 13hBattery voltage is under the limit [X] B5V,VCC output == Error code Meaning == === 20hVCC voltage is over the limit 21hVCC voltage is under the limit 22hVCC does not start up when power supply is turned on [X] B3V output == Error code Meaning == === 30hB3V voltage is over the limit 31hB3V voltage is under the limit 33hB3V does not start up when the power

I had the AC plug in my 50CT fail just a few weeks back. I wonder if you're having the same problem. I pluged in the AC cord without the battery inserted, and the system started to boot, but then suddenly shut down. I looked into the Libby's AC socket, and found that I could move one of the metal connectors. I took the system apart, and found that the plastic socket had broken into 2 pieces. I just haven't gotten around to epoxying the two halves back together. I wonder if what you're seeing is the same broken AC connector that sometimes makes a connection with the power cord, and sometimes doesn't. The batteries then sometimes getting charged, and then going dead and causing the blinking LEDs??

Yesterday my beloved libretto suddenly crashed. Everything went dark, the battery led was dark, only the DC-IN led flashes. The libretto was connected with the AC adapter to the wall socket, a 2600 mh battery was in the libretto. The led flashes an error code - I suppose: After 2 seconds off at the start, there are 4 short flashes, then comes 1 long flash (1 second) und then follow 3 short flashes. Then again 2 seconds dark, 4 short flashes and so on. It looks like 1 000. Is this a binary signal? What is the meaning? The AC- adapter seems to be ok. It gives 15,08 V and I can use the libretto with the small batteries (1300 hm). The charging of this small batteries is ok. I can use the libretto without any battery, only withe the AC-adapter. I tried a totally new battery (2600 mh), all went dark, I can't charge it. I tried a small older battery, everything seemd to be ok. Today morning I retried an older 2600 mh battery, which caused yesterday the same faults. Now the charging led lights orange, everything seems allright. When I insert another older battery, which produced the evening before the above mentioned faults, everything went dark, only the error code flashes. When I insert the new uncharged battery (2600 mh) nothing goes, the DC-in led flashes the error code. When I unplug the libretto, replug ist and then insert an 1300 mh battery everything goes. The batteries, which work, have a voltage of 12,5 V at the most outward contacts and 11,97 V between contact 1 and 3. The batteries, that don't work have slightly different voltages: 12,53 most outward, 12,03 between contact 1 and 3. I don't think that matters. I have no idea, what is wrong. The contacts of the batteries are ok. Not all 2600 mh batteries are broken. The AC-adapter charges (but only small batteries). Cheers Jürgen __ Do you Yahoo!?

I also tested the socket; it's ok too. The status is now, that 3 batteries (all are older ones, two 1300 mh and one 2600 mh) work. The libretto works fine, when with these batteries in or out. It crashes immediately and the damned error code appears, when I insert the newer 2600 mh batteries and the libretto is plugged in. When the libretto is not plugged to the AC adapter and I insert the above mentioned batteries it is not startable. Everything stays dark. When I plug in and try to charge the error code 1 000 comes. Is this the error code indicating bafterie failure? Or indicates it, that something ist wrong with the charging unit in the libretto? But I can charge the other batteries! At the moment I think, that the unprobable has happend: 2 batteries crashed at the same moment, one old, one totally new. I would like to believe this, but is there anyone, who could confirm this by translating the error code?
