Tecra A2 is not powering up

Q: Tecra A2 is not powering up

The first three lights come on,when I try to start it . Nothing else happens no noise or anything. I have tried taking battery out,starting with external power only still the same.

Does it sound expensive to fix.

Preferred Solution: Tecra A2 is not powering up

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Tecra A2 is not powering up

Can you please post a bit more about this machine?
Have you bought it as used one and now you try to fix it?

Have you maybe tried to update BIOS and now you have this problem?

On this virtual way it is not easy to offer exact diagnostic but it doesn?t sound good to me. Maybe is BIOS screwed-up. Repair can be pretty expencive.

I have a Dell XPS 410 that randomly powers off and then won't power back on unless I jiggle it a bit.

I found this: http://forums.techguy.org/hardware/818967-dell-xps-410-shutdown-startup.html

Which indicates it can be the front I/O panel causing it.

How can I confirm this is the problem, and where can I get a spare?

When it isn't powering on, the mobo isn't receiving power either.

I possess a tecra A10 complete with Windows Vista Business installed (and backed up to an image file using Easeus Todo backup


However I also have access to a Tecra M10 which came with no operating system, although the COA sticker (product key) is likewise for a windows Vista Business.


My question is: would my Windows Vista Business back up from the A10 work on the M10 (ie would it load onto the M10 hard drive and then work properly

If anyone can advise on this matter I would be appreciative please

Best wishes

A:Can I use Tecra A10 OS disk to install OS on Tecra M10?

At first I must say that Toshiba recovery image is created for each notebook model separately and it is 100% created to work on specific model. Why?
Every notebook model has different hardware platform and all drivers, tools and utilities for certain model are part of recovery image. These recovery images are also tested.

Generally speaking if both models have identical hardware platform (hardware parts) it can be used.

First of all, hello techsupportforum.com . I am happy to be here and I hope you guys can help me.
Ever since a few weeks ago, my computer does not power up on demand. What that means is after I press the power button, it would start the cpu and psu fans(not the gpu) , which would stop after a few seconds. After turning the power supply off (by removing the power cable) and turning it on again, I can try to power up my pc again. After a few attempts, it eventually starts. BUT I'm not done yet. Monitor still displays no signal, I have to press the restart button until it finally works. Please note everything works normally (except for the random shut down) until I power it off again.

This is not everything, at random times the PC would just shut down itself and I would have to power off the psu and start it again.

I have replaced my PSU with no change in this behaviour.

My spec:
Psu activ 450w w8(new one)
Gpu gigabyte gt220
Cpu amd phenom ii x4 640
Mbu asrock 760gm-gs3

Dear forum
The above says it all really.

I see the two look similar, but one is smaller. Are these two models different in other ways please.

A:Difference between Tecra A10 and Tecra M10

Of course the both notebooks are different.
There are different Tecra A10 models and there are different Tecra M10 units.

For example:
Tecra *A10-13B* supports an Intel Core 2 Duo P8400 2,26 GHz CPU and Intel GM45 chipset.

Tecra *A10-1D2* supports an Intel Core 2 Duo T9600 2.80Ghz CPU and Intel GM45 chipset

You can find details about different discontinued notebook models here:

Possibly the PSU has an intermittent fluctutation in voltage causing no post, BIOS flashes have also been know to solve cold boot problems...

I have a desktop PC that keeps dying. I thought it was the power supply because when I unplugged it from the back of the computer and then plugged it back in it would start back up. Eventually I changed out the power supply and it worked for about a month and then blew out again.

One thing though that has to be known is that this originally started happening when I was playing a game. My graphics card was very hot, I know but it was getting cooled enough I thought, but maybe not. Anyway, I replaced the power supply and it did it again. Then I went out and got a much better, higher wattage one and that one lasted one day and I hadn't even started any games, it just went out while I was on the Internet.

So I am wondering if maybe my motherboard is going bad or what. I cleaned things up and dusted it all off and still it dies. It stays on for about 5 or 10 minutes and then it shuts off. HELP! I don't want to buy new parts I don't need. Any ideas?

My computer parts are probably 4 years old now except my graphics card, which is about 2 years old. That is an nVidia FX5900 with 256mb. I know everything could use an updating though. I will get specific specs as soon as I can and post them but off the top of my head I have and AMD Athlon with 512mb RAM.
 

A:PC keeps powering off

Post the rest of you system specs. Is possible that the thermal seal is bad on your processor/heatsink causing it to overheat. This was the case for quite a few Pentium 4 PC’s with a high clock on the Prescott core. If you have a P4, this could be your problem.

My computer wont turn on. I have to take out the power cable, wait untill there isnt any electricity left then plug it back in and hope it works. Usually the fans spin for 1 second and then nothing, if i try to press the on botton again nothing at all happens. On certain occasions it actually boots and goes into windows and works fine then unexpectandly powers off. Ive got a LCD display thing that tells me what the computer is doing during startup untill windows boots. But when the fans stop spinning it just says 'Pwr_off'. Please help.
 

A:Not powering on

Hey there,

I think my first thought would be the power supply in the computer is broken. I am sure quite a few people on here would agree with that. If you are fairly tech savvy then you will probably be able to switch a known working power supply from another computer into yours to test if that is the problem. If you are not then you could see if someone you know might be able to help you with it. Or take it to a computer shop to get it fixed by a professional.

Have you tried putting the original memory back in to test it?
It may be the new Ram, ram can be very sensitive, at times
You can also test by running Memtest on your Ram too

At this stage the first things to look at, would be
Reset CMOS
Test Safe mode works or not
Try the original Ram

Hello,

I have a really old PC AT power supply which does not have a hard power on/off switch, It is an old supply with PS1 and PS2 connectors. I want to use this supply as a secondary supply for my system to power up some fans and extra stuff but I don't know where or how to start with. The system with which I want to use this supply is an ATX power supply system.

Whenever I connect this AT supply with 220v power cable it does not power on (The fan does not move). I have also tried connecting dummy loads like two old hard drives but it does not power on. The PSU is not faulty but it is not power on even with load. Tell me what should I do ?

All ATX power supplies need a 3volt connection to the motherboard to power on

Well...it says that your boot drive is D:, is that correct?

Your boot drive should be C:, while the optical drive should be D:, assuming there are only those two drives in the system.

It also says that you have a bad hard drive, whether it's C: or D: and IMO that would be the first thing to check, after ensuring that all connections are correct and that the drive is properly recognized in both the BIOS and in XP Disk Management.

Hey guys,

I've been a lurker here for a while and have finally come across a problem that I need some assistance with.

My Mom has an HP PC running WinXP. This computer has started powering off at random. I first assumed it was a PS problem and replaced it. Now with a brand new PS (OEM match) it is still doing the same thing. I thought it might be over heating so I removed the casing and cleaning all the air intakes and fans but still experienced the same issue. I've done everything from replacing the PS and power cables, surge protector, etc. I'm now suspecting an issue with the mobo.

Any suggestions?

Thanks,

Sometimes when you flip the power switch in the back of the power supply the fans twitch a little and the is a high beep that sounds like the beep a computer will make if the power supply isn't plugged into a high in graphics card, so then I thought it might be a graphics card and a tried another graphics card but it still didn't work. It wouldn't matter if the hard-drive was fried would it? it should still power on right. So leaves the cpu and motherboard.

I have a simple question...I've always wondered, is it better to leave your computer on all day and turn it off only at the end of the day, or turn it on when in use and off immediately after I'm done using it?
 

A:Powering on/off

Turn it on in the morning and off at night, or when you are finished for the day.
Reasons:
Sudden burst of electricity is bad for components.
Stopping and starting of spinning parts is arguably harder on them than leaving them running.
Warming up and cooling down of components should be minimized.

Many people I know leave their computers on ALL the time, only powering down for hardware changes or when the system locks up. Right now my computer has been on for 9 days 4 hours and 5 minutes.
Really there are only 4 reasons I can think of to turn it off if you have adequet cooling:
Saving electricity.
Leaving town.
Hardware change.
System lock up.

Of course if you are running a 9x based OS you might want to restart more often than every 9 days because 9x doesn't manage its RAM as well as the NT versions of Windows, meaning your performance will suffer after days of opening and closing programs.

i decided to swap all my PC components to the new case.
i'm 16, so i guess i may have made a mistake or 2.

however, im thinking i may need the 1000W psu as when i go to power up the PC, it powers on for about 0.5 seconds then just shuts off.

the enermax galaxy has a beeping light on it which tells you when there's a problem.
when this happens, i turn the psu off press the reset button on the psu and then turn it back on.
it does the same every time.

anyone got any ideas?
i think i may have just over-loaded the psu.
im not sure.

my OS is Windows XP x64 edition

okay, so i decided to take out all the power cables for everything except my motherboard
and the psu still does the same thing.
is this because my mobo is broken or something?

I have a Dell All in One (Inspiron One 2330) that will not power up.  I tried a new cord and also tried reset (unplugged and held power key down for 30 seconds) and still nothing.   I have no lights and no fans running when plugged in and attempting to power.   Unit is about 3 years old .... never had to search out for repair work to be done on a computer before (either handled it myself or just bought a new unit due to age) but this is not an old unit.   

First.... does anyone have any insight on steps I could do?
Second...... Is it worth to send to Dell for repair out of warranty or seek local help?

Hi,Okay so I am pretty sure I may have ruined my laptop. I accidentally spilt a very small amount of barer on it. I then freaked out wiping it off, and in the process pushing a bunch of buttons. My laptop then said it had an error and would restart itself. When it did restart there was a black screen with white writing telling me I should visit said website to get help. And then I decided to take my battery out to set it in five or oats in case it was more wet than a initially assumed. I then discovered that I didn't have any, so I just wiped it off well and placed it back in. After I put my battery back in I was unable to get my laptop to power up. I left it charging over night hoping that might help, but it didn't. I have no clue what to do or what's wrong PLEASE help

I'd like to take a cheap unpowered USB hub, connect its upstream data leads to a computer's USB port, and its 0V and 5V leads to an independent, external power source that can handle more current than the computer's USB connection.

Would this in effect make it a powered USB hub? That is, would it make it possible to safely use a set of USB peripherals that are (in combination) too power-hungry to hook up all together to an ordinary unpowered hub?

Or would it just burn up?

Recently my laptop running XP doesn't want to power off after I click "turn off computer". No music, no nothing. Hopefully someone can tell me whats going on and how to fix it. Also, because of this I can not do a re-boot. I can press the power button on the lap top and it shuts down. Thanks for any help. Chuck

I was using an 80mm fan in front of my laptop's fans to help cool it down. It was powered by an AT power supply. Is there any way to make it run on one of the ports. it is a gateway m505x. I could do USB, firewire(4 and 6 pin), printer port, video and svideo ports, modem jack, and microphone/headphone. I am shooting for the USB, but any of them would be fine.

Can any of these power an 80mm fan, and how do i connect it. It has only a positive and negative cable.

Help! I am new to this board and sadly the most knowledgeable computer person in our office. Which is not saying much. I have a Dell PC I think one of the firsts pentium 4's. I has been working fine but yesterday it just wouldn't turn on. I opened it up and it was quite dusty so I cleaned it out. I plugged it into what I know to be a working outlet and with the cover off noticed a flashing light on what I believe to be the mother board. When I unplug it the light goes out so I assume the PC is getting power. Any Ideas? Thanks.

Sorry its me again, it seems on my last post I had RAM that wasnt supported by my motherboard even though my motherboard said it supported DDR266 RAM. Anyway I sent it to Tigerdirect.com Store here in Miami to be fixed, so they did and I played my games for about two hours last night. So this morning I turned on the computer and the game I was playing was loading up and all of a sudden my computer just shut off. So I waited for it to cool down for about 10 minutes, I disconnected and reconnected the power cord I pressed the power button but it doesnt turn on now. So I waited a little longer and disconnected the extension, the outlet, and the power cord and reconnected it. But it still doesnt turn on! I think it was a cooling problem but even if it was it still wouldn't turn on. Please someone offer some suggestions.

I used to turn on my computer and walk away. Two to three minutes later it was up. Then one day last week, it decided to stop the start up and make me click on my name. How do I put it back to just turning it on?
