I fixed the memory problem on my Tecra 8100 it was 6 pins in slot B that solder had come loose 3 pins on both of the outside.

Other problem is AC power. I have to put pressure on the cord for AC power to work. I resoldered but no success. I may try again later.

As for your screen going blank, I’m not to sure. Usually it’s the inverter board other times its the lights. I’m trying to fix an LCD monitor thrown out at work and the invertor section of the board is gone. Couple of diodes blown and some failing capacitors and transistors. I know which ones, all I need is to find the time and the parts to do it. Best of luck! I’ll see if I can come up with something.

This has been very helpful, I also have a tecra 8100 which is exhibiting similar screen problems, only the screen is premanently black, I can however see a faint outline in the right light when I turn it on.

I have tried replacing the inverter board, but this has not worked. Can you advise what else may be the cause of this problem?

Grateful for any tips

One was thrown out at work and I grabbed it.

It works somewhat, but I think it was dropped. Sometimes it freezes up during startup then goes to blue screen and says stop: 0×0000007f then the rest 0x… are zeros (which means hardware failure somewhere). Anyways I loaded knoppix (live CD) and ran the memtest right from prompt and it seems to run fine until I push near/around the top left of the keyboard (I think right above the processor) and then the memtest starts continuously listing off errors as it runs the test until I push in that area again, but it’s intermittant and mostly gives errors. Couple of times I did manage to get knoppix fully loaded but as soon as I tapped that left corner the screen blanked and it froze up.

Anyways, how do I take it apart so I can look to see if the processor is seated properly. I can’t seem to crack the cases in half. I’ve removed screws, hd, battery, modem, dvd drive as shown in the toshiba 8100 field service manual but it doesn’t give any direction on how to split the two halves to, say, change a processor. I’m kinda stuck.

Any hints or tips would be greatly appreciated. Maybe the best tip is to just get rid of it but I would hope someone would have some type of skill to help me out.

Again, greatly appreciated if anyone could.

I have a problem with my Tecra 8200 where the AC adaptor LED (left most LED) is flashing amber. I suspect a problem with the internal PSU but I cannot get access to it. Does anyone know how I could dismantle this machine further to gain access to this?
Thanks very much in advance,
Peter

Mike C,
First of all thank you for your generous donation to http://www.irisvista.com
Now regarding your problem.
There is no simple answer but I would definitely run diagnostic tests on memory and hard drive.
For testing memory you can use Memtest86+.
For testing the hard drive you can use Hitachi’s drive fitness test.
I linked to both utilities in “Useful Links” on the right side of the website.
Also, make sure you have the latest BIOS installed. Update the BIOS if needed.

Excellent instruction and guidance – thanks! Your info quickly solved 2 frustrating problems with my wife’s Tecra 8100 (intermittent LCD backlight and a loose lid), thereby postponing the cost of a replacement and restoring marital harmony!

But 1 issue remains. When returning from standby, a “resume failure” error frequently (but not always) occurs, forcing a system reboot. Any ideas of what’s going on here? Marginal RAM maybe? BTW, battery condition is fine. I ended up disabling standby and forcing hibernation instead, but it’s not ideal.

Any help would be much appreciated!

Cheers,
Mike C.

I bought a Tecra 8100 with the same problem: screen turned faint frequently after 5 min. However, I did not change the inverter. From a web, I got an information that you just need to pull out and plug in the power connector to the inverter for five times. It is quite unbelievable but I tried and it worked like a charm. Five months have passed the computer has worked perfectly.
