Toshiba Satellite 3005-S303 POST code beeps

Posted on 2004-09-17

I just finished replacing a keyboard on a Toshiba Satellite 3005-S303 and when I went to power it back up, I am now getting a POST code beep sequence of 1 long, 2 short (long-short-short).  What does this sequence mean and is there anything I can do to troubleshoot it?  I checked all the connections from when I had the keyboard off and everything seems secure.

It most likely means that something else (not necessarly directly related to the keyboard) got disconnected or jarred loose.

I would take the keyboard completely out first.  Then I would look for all ribbon cables and socketed cards/daughterboards and firmly push them back in place.  If you have to, pop the clip up for the ribbon cables, then push the cable back down, then pop the clip back in place.  Then while the keyboard is still off, try powering it up (a laptop can work fine without a keyboard, this is just for testing purposes).  If it works, then add the keybaord and test again.

Also check the memory to make sure that the memory chips didn't get jarred loose.

I have seen that the long-short-short code can be related to video.  If this laptop has a seperate video card daughterboard, make sure its firmly seated (pop it up, reseat it firmly).

Before I saw your response, I took the keyboard out one more time and reseated the connectors. Now, I am getting different behavior. The computer is booting up without the beeps, but we're still not seeing any display. I know it's working properly because it's plugged into our network and I used XP's Remote Desktop Connection to connect to it. However, since it's a terminal session, I cannot tell if the keyboard is actually working. I will try your suggestion of booting it with the keyboard out, and I will also check for loose memory and/or any other cards.

FYI - I also tried plugging in an external monitor, and I get nothing from the external output either.

I did notice the following entry in the XP Event Viewer:

The following boot-start or system-start driver(s) failed to load:

Not sure what device that is referring to, but I'd have to guess it's referring to the keyboard or touchpoint?
Portable, direct connect server access

The ATEN CV211 connects a laptop directly to any server allowing you instant access to perform data maintenance and local operations, for quick troubleshooting, updating, service and repair.

Okay, after checking on this, I don't think SYMTDI has anything to do with this problem. That's just Symantec Antivirus.

Its got to be a video daughter board or ribbon cable that isn't seated properly.  I would tear it down once again and maybe even tear it down further than youi did just to get the keyboard out and reseat everything (loosen clip, remove cable/board, reseat cable/board, secure clip).  Then test again.

The reason why i say that is because i remember some toshibas had video daughterboards (and some dells too as well).

I cannot locate  daughterboard, but I'm not exactly sure where to look for it. Once I've got the keyboard off, there are only so many more compartments and none of them look easy to enter. I did try booting without the keyboard, and still had no video (got the long-short-short beeps). I also tried reseating the connectors of the keyboard and trying again, still no luck (no beeps, but still no video). I did find out that this laptop has had a history of problems with video not always working, so there is probably something loose in there somewhere. It's a shame Toshiba does not make repair diagrams available for out-of-warranty computers because it would make this so much easier.

It must have been something not seated properly. I tore it down a third time and reseated everything and now it's working. Thank you very much for your help!
