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.

Hi
I have a Toshiba Te2100.The weirdest thing happened around 2 weeks ago.
My Daughter started up the laptop and she said something was wrong with the laptop
When I checked it out, the screen was full with vertical lines and won’t boot up only in safe mode. So I restarted the laptop and see what’s wrong, but when the laptop restarted, I couldn’t read the dos text because this time it had horizontal lines and the monitor is flickering. I connected it to an external monitor but it was doing the same thing.
I forget to mention it on boot up no beeping sound. So I disassemble the laptop to see maybe a lose connection but I didn’t find anything. I start removing all the parts one by one so maybe I can hear some beeping sound so that can point me which part is not working in my laptop but no beeping sound, unfortunately I stuck on this point and I really need your help to work it out what can be a problem with my laptop.
Thank you, for you help

shocdoc,
I believe Toshiba Satellite Pro 6000 has video card integrated into the motherboard, that’s why you cannot find it.
Test your laptop with an external monitor. Connect the monitor to the laptop via VGA port and set the laptop to output video on both screens. Wait until the laptop fails. If video on the external monitor fails too, most likely you have a problem with the video card.
Check the fan, make sure it spins. I think this problem could be related to heat issue.

Sorry, the above post concerns the 6000, not the 6100. I don’t see a particular video card, just a thin chrome plate where the video card is on the 6100. Thanks.

I have looked through the above posts and think I have a pretty good idea of what may be wrong with my Toshiba Satellite Pro 6100; however, I want to describe the problem and see if you have any other thoughts besides taking it apart (which I am doing right now) and re-seating everything. The machine starts fine, loads Windows fine, etc. The screen looks fine with no lines or anything. It looks totally normal. Then, after anywhere between 5 and 60 minutes or so, all of the sudden the screen goes white with blue vertical lines about a quarter inch apart. The machine keeps running, meaning that the hard drive and fan do not stop humming at all when this happens, but I can’t do anything when this happens. I turn the machine off and then it absolutely will not turn back on for 10 or 15 minutes. I tried the holding the power button for 10 seconds, but that does not cause it to turn on any faster. After it decides it is going to turn on, it goes through the disk check, which I let it finish, and then turns on and runs fine until the screen goes white again. Any other thoughts than re-seating all of the power connections and such? The reason I ask is that if you think it is more likely a motherboard or video card issue (or some piece of hardware that needs to be replaced, I just as soon do it right away. Thanks in advance.

Alec Numa,
You see the same line on the external screen, right? Most likely this is a problem with onboard memory module (soldered to the motherboard). I don’t know if it will allow you to run memory test, but you can try it. Run Memtest86+ and most likely it will fail.
Here’s my post dedicated to Toshiba Satellite A60 and A65 problems. Read through the comments.

Correction to previous post:
The screen featuring “TOSHIBA” is diplayed for 2 seconds and has VERTICAL black discontinued lines all over.

Satellite A60 PSA60E with Windows XP Home Edition:
System does not start at all and I have gone through most suggested procedures.
The screen featuring “TOSHIBA” is diplayed for 2 seconds and has horizontal black discontinued lines all over. The Toshiba logo looks as if it has cracks in it.
What is the problem.
Thank you for your help.

Continuing the above problem , the error code is 82 which reads as BGVSNS voltage is not more than 1.02V when the computer is booting up….
