Question about Toshiba Satellite L455D-S5976 Notebook

1 Answer

My laptop turns on but has black screen. power plug light comes on and the power on light comes on but nothing else. the hdd light does not come on or blink, flas or anything. the hdd sounds like it is running and the cooling fan kicks on but thats it. i tried the memory thing changing slots taking it out and wait for it to beep indicating no memory, nothing. tried looking for dim screen to see if the backlight was bad all that. so does this mean that the hdd is dead?

If turning it on with no RAM installed doesn't make it beep to indicate no RAM, it's sounding like it is the motherboard that is damaged.

If the computer is still under warranty, I'd suggest taking advantage of that warranty to have the motherboard replaced. If not, you are better off just buying a new computer.

SOURCE: Toshiba Satellite A15-S129 PC Notebook will not turn on

I have the same problem. What I have found with mine is that if I can get the battery to take just a little charge then I can get it up and running. Here is how I do it. Disconnect AC power leave the battery in and start the laptop. As soon as thing start to run I plug the AC back in and it works fine from there on. Now mine is flashing as well now and I have a dead battery and it will not restart. Something I have noticed thought is it appears that the yellow light is blinking a code. This is what I have come up with. I appears to be flashing 323 as the code or could be 2 shorts 1 long then 2 shorts and then 3 shorts.

Anyone know where to find info on these flashing codes.

Thanks

SOURCE: Toshiba laptop will not turn on, screen is completely black

Don't pay attention to your uncle. I had the same problem. Blue ring, power lights on. Sometimes the laptop would come up after a few minutes and then would freeze. It is a power problem. The AC jack may be broken and, most likely, you need to get the MAX1632A power controller (a 40-48 pin black IC next to the AC jack) resoldered too (get someone qualified to do it, with the right soldering station for surface mount work).

SOURCE: toshiba a135-s2356 laptop no bios screen on power up

Hello,
There are 2 ways you can reset your bios2_bing.gif.

1. On the motherboard there is a small watch battery. Remove this battery along with the power cable from the power supply. Hold down the power button to fully discharge the system. Wait 2-3 minutes then reinstall the battery2_bing.gif and plug in2_bing.gif your system. Your reset is now complete

2. Some motherboards have a 3 pin jumper by the battery. Lets say that the jumper is on pins 2 and 3. Remove the jumper while the machine is OFF and place onto pins 1 and 2. Power on your machine for a minute. (Note: Your system will not POST). Shutdown your machine and put the jumper back to pins 2 and 3. Your reset is now complete


This is a great troubleshooting2_bing.gif step for those of you having POST issues or no POSTing at all. Like other troubleshooting2_bing.gif steps, this will not always work but usually will depending on the problem.

Please let me know if you have any further questions or concerns.
Thanks.

How do you switch off you laptop? Try this press and hold on the power button for about 5 seconds. So it won't boot to windows? When you turn on the laptop and you see the dell logo keep tapping on F8 then try booting in safe mode, if fails do F8 again then last known good configuration, if fails do F8 then startup repair, if fails do F8 then system restore, if all fails reinstall os. but before all these steps try to test hdd first. make sure laptop is off. press and hold on the Fn key then press power button. Run the PSA test and once it finish it will show you some errors code like 0142 -0146 means hdd needs to be replaced.

Have a Eee PC 701 SD. I can turn on the laptop but once it's on nothing is displaying on the screen. I tried every button possible but nothing works.


Its possible that the LED light that illuminates the screen is dead. If you look very closely can you make out any information on the screen or is it absolutely black? If you can see text or Windows, then its likely the backlight.

If you cant, try plugging an external monitor in to see if it is even booting. Also look at the HDD light (bottom right of the keyboard) to see if it flickers on and off while starting. If there are no lights, then you may have a dead unit... Get er fixed.

Laptop wont turn on philips freevents x51


The most likely problem is that your Hard Drive has Died.

If you can readily access another Laptop HDD, try it and see.

Other than that, I'd say the Motherboard has decieded to give up the Ghost.

Just Remember, A Laptops life expectancy is 3 years, after that you are treading on thin ice keeping Important Documents on it.
