Tecra notebook I have just bought a new Tecra. Fan is running, screen is black, battery appears to be charging when mains connected, but can't seem to turn off / reboot / see anything on screen. Toshiba warranty helpdesk closed - can anyone help / make any suggestions? Thanks in anticipation...

dont they all , eventually. all do a fact. but why ? so leave that old battery out, run on AC for ever if you wish and for SURE TESTING. they love to fail and overload the PC. so with AC good power pack no main battery does the power turn on? y/n does the fan run (above is yes) does the cd tray eject does the bios message show on the screen, it must "hit f10 to setup?" means BIOS page. does it, or is the screen back totally no text EVER. even hitting the F10 key or the key it told you to hit for 10 years. that is called fan running and not packed up. the black screen of *****. we have no idea what YOU can do, your skills your tools, ? how can any person know that. if not black screens of deathh then say so and say what you saw fully this time. http://pcdied.com/black-screen.html its a nx9020 (2004, 13 long hard years old.!!!) not 9020, the nx matters . big time top black screens fan ok are? COIN cell dead. CMOS RTC battery coin main battery shorted, nah its parked on shelf. CCFL lamps it PC are dead. as all are this old do the flash light trick yet, fan blowing.

If you unplug your laptop from wall power, will it run on battery power?

Check to see if the cooling fan is working properly. You should hear it running if you put your ears close when the computer is on. If the fan is working and the cause of overheating is not the fan, then you may have a deffective battery, check to see that the battery can take up charge. If the battery is fine, then you may have a chip inside the computer that is overheating because of internal defect. This job would be best left for experts.

THis happened to my Tecra M4 4 times in 4 years. Each time was a motherboard replacement at the tech repair shop. Each time cosint about $600. I have heard of the heating method to reflow the solder but don't know how to do it. Others have paid for the motherboard replacement and modded the GPU fan to constantly run. I may get it fixed once more and try using a laptop cooler to keep it from overheating again. Because it is soldered on to the motherboard, they replace the entire board.

Most possible one of your Toshiba Tecra m4 driver is not working properly, but don't worry give me a call at +1 (833) 493-0111 so that i can suggest you the right way to fix it!

Try a new battery and if the new battery wont charge then its either going to be a bad ac adaptor or a bad motherboad. If the new battery charges then you'll know that the old battery went bad.

If you see a very dim image or black screen or flicking image on the LCD screen it means you have a backlight problem.

Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.

Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

plz try by resiting the ram, if the problem persist then you have problem in display adapter,send it to the vendor from whom you have bought

what's the model number ? ?

Hello,

My name is Vikram Kumar Thumu, from India-Hyderabad. I have seen your message on the issue . I would like to provide my suggestions on the issue. I hope that this should work for you and will resolve the issue.

well, the issue seems to be with Battery , it is not working properly any more. or it could be an issue with Battery drivers in PC.

To isolate the issue, I recommend you to try below steps. This will resolve the issue .

Step 1: Connect Battery and Also AC power adapter, try to charge the Battery for around 6 hours. Make sure that notebook is idle for 6 hours, do not try to run any application . Just let notebook be ON for 6 hours with AC power with Battery in, so that battery gets charged up.

Step 2 : Once if you are done with 6 hours of Charge, now disconnect the AC Power. Restart PC and let the PC run on Battery only. Check out how much time PC is able to run on battery. If PC powers ON properly with battery and runs around 40 minutes then it confirms that Battery is fine else if PC do not startup properly or if it works less than around 30 minutes on battery then it confirms that it is an issue with Battery. If found fault with battery then try step 3 process.
