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.

Nirajan,
It’s hard to say what is wrong, it’s necessary to test the laptop with a known good battery to narrow down the problem. I think you might have a problem with the motherboard.

I have had a Toshiba TE2100 model PT210A-006QT
for 4 years. This the 5th laptop I have owned. IT has been the worst performer in terms of failure of the keyboard, screen and power supply (incl external power supply). All these have been replaced. The most consistent problem is the screen which flickers. After many returns during the warranty period for “repair” it is now out of warranty and I will have to repair it myself. Once again the screen flicker has become an issue and (thanks to the advice on this thread) I am buying a new FL inverter. The part I ordered was V000010160. Due this being out of stock, the part I have been offered is P000327640.
Can anyone tell me if I should wait for the original part or is the alternate better?
Does anyone know why the inverters fail? Is it heat related? Would more ventilation help?

tecra 9100, over-temp problem. I’ve seen three machines go like this in as many weeks, & I’m not even a pc engineer- my experience is with broadcast equipment. but these lappies were going to be scrapped so I had a go at the problem…. first, it looks like the cpu fan has failed. you can’t hear it or feel it & the machine shuts down or freezes with a message about being too hot.
well.
the fans are fine. it’s the little IC near the fan connector- you can follow the trace back to it on the pcb. this is supposed to run the fan at full or half speed, depending on cpu temp. when it fails, no more fan. so I rewired the things & now the fan runs at full speed all the time…. happy laptops again.
hope this helps someone.
duncan.

all is fine now - i am writing this with my TE 2100. maybe this is important for those sharing my problem: make sure the power board is not only cable wise connected to the motherboard but also plugged in with the connector on the other side of the board (a connection similar to the vga board slot)

Dear CJ,
I am pretty desparate - TE 2100 - no warranty - Boot problem -(power board - mainboard). ordered a new motherboard - still the same problem.
it would be great if you contacted me via email to help.
problem: pc crashed often and was finally dead. at least though, it gave me a green LED when connecting to AC. Now I have two motherboards and power boards (the old ones and the new/used ones that I ordered). both fail to show a green light when connecting the motherboard to the power. both do not boot. can you help?
thank you so much!

Paul,
Sure, you don’t have to remove all these stuff, go straight to the step 23. It shows how to remove the power board.

My TE2100 is having the same problem of not booting up and the power light flashes orange. I’m in the process of disassembling it to reseat the power board to the system board. Just finished step 18. Just wondering, after step 18, can I skip some steps to go straight to reseating the power to the system board? Which step number actually reseats the power board to system board?
Thanks!
