Why Toshiba Tecra TE2100 laptop locks up or will not boot at all?
One of our biggest customers use a lot of different Toshiba laptops and one of the models is Toshiba Tecra TE2100. We repaired many of these units and we noticed that some of them had very similar problems:
- Laptop locks up when you move it or sometimes freezes by itself. The video is still on, but the acupoint (keyboard mouse) and the keyboard itself do not work anymore.
- You can start the laptop, but you see CMOS (RTC) battery error on start up. After you clear the error, the laptop boots fine. After you reboot the laptop, you get the same error.
- Laptop will not boot at all. There is no power or power LED blinking. There is no hard drive activity. There is no external or internal video.
- When you press power button, laptop shows some activity, but there is no video on LCD screen.
At the beginning, when we just started working on this model, we tried to fix CMOS (RTC) battery error by replacing the RTC battery. Unfortunately, it didn’t help to fix the problem at all. We found that the main culprit of the problem is a poor connection between the system board and the power board (CMOS battery is connected to the power board). In some cases you can fix the problem by reseating the power board. Carefully disconnect if from the system board and connect it back. Turn on the laptop and see if it fixed your problem. If it didn’t help, most likely you have to replace the system board and the power board. Unfortunately, I cannot say exactly which one is causing the problem, the system board or the power board. The same story with laptop lock ups, try to reseat the power board.
You can fix a video problem by reseating the video card. We noticed, that over time the video board pops up from its connector on the system board and you can get video if you push it back in place.
Conclusion: before you start replacing parts, disassemble the laptop and try to fix the problem by reseating the power board and the VGA board. My disassembly guide for Toshiba Tecra TE2100 can help you to take apart the laptop.

Kevin,
Removing and replacing the FL inverter board from Toshiba TE2100 would be almost the same as for Toshiba Tecra 8100. The only difference would be:
1.Toshiba TE2100 LCD mask is secured by four screws. Two on the top and two on the bottom of the LCD mask. You’ll find these screws under the screw seals.
2. The FL inverter board in Toshiba TE2100 is secured by one silver screw in the middle.
That’s it.

Hi there,
Thank you very much for the disassembly guide for TE2100. Mine had the “fainted screen” problem. (you know, the screen blanks, and if you look really closely, it’s actually fainted). I’ve sent my laptop to the repair centre twice for this problem, and they’ve replaced the video board, but nonetheless the problem is still recurring.
After searching around the net, I’ve come across some articles pointing that the problem might be with the FL invertor. There’s a guide on how to pull out the FL inverter on TE8100. I wonder is that the same for TE2100? I’d appreciate it if you could answer my question.

[...] Toshiba Satellite Pro 6100 disassembly guide will help you completely take apart the notebook to remove and replace the system board, the power board and the video board. Toshiba Satellite Pro 6100 notebook has some known problems very similar to Toshiba Tecra TE2100. Overtime the video card pops up from the connector on the system board causing unpredictable video problems. If you experience a video problem try to press on the video board so it makes a better connection with the system board. Also you can experience a problem with starting the laptop. When you press on the power button the laptop will not start and the power LED flashes orange. Most of the time it happens because of a poor connection between the power board and the system board. In some cased you can fix the problem by reseating the power board. If reseating the board doesn’t help then the system board and the power board has to be replaced. One more problem – you can get the CMOS (RTC) battery error each time you turn on the laptop. If replacing the battery doesn’t fix the problem then it might be also caused a bad connection between the power board and the system board. Try to reseat the power board. [...]

CJ,
Guess what, last night I went for it with one last board and whalaa, a fully functioning A75 again. No lines, etc. The only thing was the AC seems to have a short or something. Could be the power cable, we’ll see. Functions beautifully on the battery. After all this trouble, I’m a happy camper. Thanks for all your help.

Joseph,
It’s a very weird problem! I would suspect the system board first, because it displays lines on the LCD and the external monitor. But you say that the board was replaced 3 times. Weird!!! You can try to take the laptop apart completely and assemble it on the bench, without the laptop case. With Toshiba Satellite A75 you will only need the system board and the CPU with heatsink and fans attached. The board already has an integrated memory module. After that connect it to the external monitor and turn it on. You should be able to get Toshiba welcome screen. If you still get the same lines then it could be the CPU problem. I have never seen before a CPU causing lines on the screen.

OK, Here’s what I’ve tried so far.
1. External monitor-lines
2. Boot in Safe Mode-lines
3. Boot in bios- lines
4. disconnect wireless card-lines
5. 3 motherboards-lines!!!!!
Wow, should I just dig a hole and gently place it in?

CJ,
Thanks. The external monitor test yields the same results: lines. How do I reinstall the driver? I only have a few seconds before it freezes up on me.

Hey Joseph,
Here are some tips on troubleshooting laptop video problems. First of all, if you experience the same problem with 4 different motherboards then I’m 99.9% sure that it is not a motherboard problem.
I would try the following troubleshooting steps:
1. Connect the laptop to an external monitor and see what video output you get on the external monitor. Is it freezing too?
2. Boot the laptop in the safe mode. If you get a good video output is the safe mode, then most likely it is just a software problem. You can try to reload the operating system back to factory settings from a restore DVD (backup all important data before you run the restore DVD).
3. Disconnect the display from the system board and try to start the laptop only with an external monitor attached. If you get a good video output, then most likely the display assembly is causing the problem.
4. Test the memory modules if you have any extra memory modules installed.
5. Try to start the laptop without the wireless card installed. Sometimes a bad wireless card can cause very strange laptop problems.
By the way, have you tried to reinstall the video driver?

HI.
I have a Satellite A75, out of warranty, of course. When it’s turned on, it begins to boot and can usually get to the desktop and then the screen freezes with colored lines. It usually stays on for >1 minute before this happens. Everything pointed towards a video problem and I have gone through 4 motherboards purchased on ebay trying to fix this! My computer tech. finds each one doing the same thing. What is going on???
Thank you very much,
Joseph Henson
