Solved Black screen on toshiba satellite laptop

December 31, 2010 at 14:56:41
Specs: Windows Vista, AMD turion64

I powered on my toshiba satellite (harman/kardon) laptop (2 yrs old) and the power light comes on, the hard drive light flashes,CDrom initialized but the screen never changes from black. I have tried connecting a working external monitor and nothing shows on the external monitor. I have tried powering the laptop on battery, and connected to AC with& without battery, but display still does not change from black screen. Has anyone seen this problem before and/or have any idea what is wrong? I'm guessing the display is bad. How can I verify?

Thanks
SteveB

I have solution maybe you can try cause i have same problem,
So there are many problems which will cause issues of the screen.

1. Software
- Try Fn + F5 or something like that

2. Electrical
- Remove battery, unplug power, hold power button for 60 seconds, turn on computer with power plug only, then shutdown, add battery and restart

3. Magnetic On/Off Switch to detect of Close/Open Lid
- Your magnet switch is fubar some how. Open up the speaker cover and see if your lid actuator switch that come in contact with the magnet on your lid cover is stuck or not (find where the magnet is in the back of the front lid cover, trace where the magnet area actually touches the base of the computer and you will find the switch)
- Workaround, start windows with lid at 30 degree angle

4. Hardware
- You need to replace either Inverter, Blacklight, or everything. =)

I have tried the second and its work .. =)

I don't see anything on the screen, hence, I get no chance to boot to safe mode.
Thinking back, if the external monitor shows nothing, perhaps its more than the display gone bad. Thanx for the response.

I would say try a different power AC adapter, if it's not putting out enough (even if the light is on it) power it won't turn on. Your laptop is too new for the display to be gone I would say.
Check e-bay, great deals on adapters

Hmm. After reading your response, I decided to check out the adapter issue(hoping that was it): My girlfriend has a toshiba laptop, a satellite - not exact model, that is working fine. The adapter, from the problematic laptop has specs
input: ~100-240V, 1.3A & output: = 19V, (3.95A)
while from the good toshiba laptop, the specs are
input: 100-240V, 1.5A & output: = 19V (4.74A)
both 50-60 hz.

Both adapters work fine with the good laptop and neither adapter works with the problematic one... shooks....I gather thats not it.

Ay, thanx

I have the same problem with a Toshiba Satellite harmon/kardon. A friend gave it to me and said the camera wasnt working and asked me to fx it. When I got it home it was turning on with the same symptoms posted here. I did exactly the same steps you did and even tried another battery but no luck. Doesnt even appear to be booting to BIOS and/or Display is not even beginning to illuminate, and never here the HD begin loading windows (except initial HD 1 sec after turnig on),which makes me think its not just dsiplay, maybe MB?

I was able to get the computer to finish booting, or come back to life. It does appear to be a possible power issue or MB issue. I beagan pressing around the sides, but not too hard, near where the power connects and the opposite side, and the computer made a rebooting sound, screen illuminated and it is on and running OS just fine. However, the orignal issue, camera no working, is still happening. I still believe this to be a failing MB or realey poor desine on connection as two appear to be failing. The OS and the sytem does not recognize the camera at all.
Good Luck!

After playing around with the laptop for a while, I found out there is some kind of short on the computer around the power switch. I was able to turn on the computer by pressing down the area around the power switch - doing that the power switch made connection and the unit came on. From that point, the computer has been working with the power switch, but I do feel it won't be for long before it goes bad again. If/when it goes bad, I'll open it up to try and figure it out.

I have the exact same problem with my Toshiba Satellite T135D. It worked fine prior to sending it to Toshiba for a recall repair. Now, I sporadically get a black screen with the power button on. Now, I did notice that the little round internal storage light IS NOT lit when my screen is black.

It is loaded up now fine after turning it on and off 20 times. But, I don't know for how long. Any advice what this may be is appreciated.

SOLUTION:

Hey everyone, this was bit of a struggle to resolve. After googling still could not find the solution to this problem. Finally, I tried changing different BIOS settings on my own.

You need to change the "Dynamic CPU Frequency Mode"

Change the setting from

"Dynamically Switchable"
- to -
"Always Low"

This will solve the problem.
This has been tested.

Good luck !

I just had this problem with my Toshiba Satellite. I noticed my internal storage button wasn't lighting up like it should whenever the laptop turns on. Now I have an orange low battery light and is constantly on, might have something related to do with it?

Well, being angry over the issue and remembering that sometimes a little banging will help some electronics, I banged it lightly over my knee, started it up and it worked. Still don't have the actual cause to the problem but I do remember letting the computer hibernate for over 24 hours...

I opened my Satellite (top compartment) and so I solved my problem. Maybe was due to a cable bad positioned.
