Toshiba m35x starts /stops intermittently with no power to display monitor


By whom Kathleen? You?

I ask because there are two ways to answer this;

1) You performed the procedure, and less for me to post.

2) You did not perform the procedure, and I need to explain from the beginning; using a diagnostic flowchart, pictorial guidance, and guidance from me.

While I wait for your reply, suggest perform this simple test first;
Laptop OFF, monitor OFF, attach an external monitor;

1) VGA monitor to RGB (VGA) port on left side of laptop.
Can use a CRT type of monitor (Looks like a small TV), or flat LCD screen monitor if it has a VGA cable.

http://en.wikipedia.org/wiki/VGA_Connector

OR;

2) S-Video port on left side of laptop for TV, or external video display device

http://en.wikipedia.org/wiki/S-Video

Turn the monitor on. If a CRT type allow it to warm up.
Turn the laptop on.

By factory default settings, the display should show on the external monitor. (Display device)

If not there are 3 display options available;
1) Internal monitor of laptop ONLY
2) Internal monitor of laptop AND external monitor
3) External monitor ONLY

Press, and hold the Fn key down, and at the SAME time tap once on the F5 key.
The F5 key is the Display Toggle-Over key.

Still no?
Hold the Fn key down again, and tap once more on the F5 key.

Display on external monitor means there is a problem with;

A) Video Cable
B) screen Inverter
C) LCD screen

Which means if computer display was working correctly before;

1) Whoever repaired it could have used the external display option, and it needs to be set back to internal

2) The Video Cable connections are not tight, not correct.

Loose at motherboard, screen Inverter, or LCD screen.

3) Anti-Static Procedures were NOT followed, and laptop is now an expensive paperweight.

Post back in a Comment.

My 18 month toshiba satellite lap top battery is not taking a charge.


I had a similar problem with a Toshiba laptop. Problem was an issue with the bios being out of date. Go to the Toshiba website, download the bios for your model and install per Toshiba's instruction. That should fix the problem.

My dell inspiron 6400 won't start, red light then green light flashes ansd nothing happens, try to take out the battery and putting it back, no results, help


The following troubleshooting guidelines are basic troubleshooting steps. Battery Charging It is recommended to charge the battery while the system is off for faster charge times. Users may notice longer charge times when the system is powered on and running graphics extensive applications.
No POST If the system does not perform a Power On Self Test, there are various things to look for:
  1. Check to ensure that the system has a power light.
  2. If the system has no power light, ensure that it is plugged into AC power. Remove the battery.
  3. If the system has power but is not performing a POST, check to see if the keyboard status lights flash to indicate a successful POST, but no video, or that the keyboard status lights are lit in a sequence indicating a system problem.

  1. With the power off and the system unplugged, remove all CRUs from the system and reconnect that AC adapter to the system and try again.
  2. Run the On Board Diagnostics (OBD).
Video If the LCD on the system shows no display, or has other LCD problems, there are some basic steps to take:
  1. If the LCD is not displaying video or the video is garbled, run the BIST Test.
  2. If the LCD is not displaying any video, connect an external monitor to eliminate a no POST problem. A good image on the external monitor eliminates a video card problem or a POST problem.
  3. Connect an external monitor when possible for all LCD related problems, to help eliminate a software possibility or video card problem.
  4. If the LCD has extremely dim video, attempt to adjust the brightness or connect an AC adapter to eliminate a power management conservation setting set in the BIOS.
  5. If the LCD has lines on the screen, check the system during POST as well as system setup to verify if the lines are present in all modes of operation. Run the BIST Utility.
  6. If the LCD has color problems, run the BIST Utility.
  7. Run the On Board Diagnostics (OBD).

My monitor comes up during start up but after 60 seconds or so it goes into sleep mode? and the monitor goes black


You might have it connected using the wrong port on the back of your computer. The monitor will display the BIOS and post messages but once it gets to windows it will turn off. The other possibility is you need to either reload the driver for your video card, change the default display device in the bios, or replace your video card.

I have hp dv6500 i update my bios and my display is total black just light blinking pls help me wht i do ?


This could be due to hardware malfunction of the video card on the notebook. To isolate this, perform the following steps.
*** Hard Reset ***
To perform a hard reset, please follow the steps listed below:

1. Unplug the AC adapter from the notebook PC and remove from any port replicator or docking station.
2. Remove the battery from the notebook battery compartment.
3. Press and hold down the power button for about 20 seconds.
4. Insert the battery and plug the AC adapter back into the notebook PC.
5. Press the power button to turn the notebook PC back on.
After performing the above step, if the issue persists, then connect an external monitor to the notebook and check if the display comes on external monitor or not.
*** External Monitor ***
1. Turn off the notebook.
2. Connect the monitor cable from the external monitor to the monitor port on the rear/side of the computer.
3. Connect the monitor to a power source and turn it on.
4. Press the Power button to turn on the computer.

At this time, please follow the instructions mentioned below for switching the display to the external monitor:

The notebook's video card supports three modes. Built-in screen only; external video only; and both on simultaneously (mirrored). If you're not seeing the image on the desired device(s), the notebook's video card is probably in another mode. Press FN + F4 to cycle through the display options: Notebook display, External monitor, both.

If you press FN + F4 once, the external monitor will display & there will be no Notebook LCD display.
If you press FN + F4 twice, the external monitor will display & there will be some shading on the Notebook LCD.
If you press FN + F4 thrice, both Notebook LCD & external monitor will display.

If the issue persists on the external monitor, then this could be due to defective video card on the notebook. However, if the display on the external monitor is fine, then the issue is with the LCD display panel of the notebook. In either cases, the notebook requires a detailed onsite diagnosis by a service technician.

Not booting up....seeing the power and battery led.


Ok it seems you should check its ram module. Reseat it or clean at the most with soft eraser its edge connector. But you should first disconnect its battery and other power source, and shut down completely before performing a cleaning on ram module.

No display at post


There are a few things that can cause no display on the monitor.
That single beep means POST = Power On Self Test. Post has tested everything on you're board to be good.
The cable between video card & monitor may be bad or not connected correctly (Swap out the cable as last resort).
2. You're monitor is defective, try swapping it with known working monitor.
3. You're video card is not functioning.
Lastly, when you reset the system cmos/bios everything went back to default. This means you're bios is now using the onboard PCI video graphics. Remove you're radeon 9600 video card. Try booting the system. You should see display again. The only way to test you're radeon would be to boot to the bios & set bios to boot using the AGP radeon. You need to change Init Display First to AGP & not PCI. If you loose video than you know you're AGP card is bad. Reset the cmos/bios before adding another AGP card or you will not get display. This setting is on pg 3-5. Integrated Peripherals. If you need you're manual you can download it from this link: http://www.abit.com.tw/page/en/motherboard/motherboard_detail.php?pMODEL_NAME=NF7-S2G&fMTYPE=Socket+A

Good Luck!

Mag monitor doesn't display bios post


I have no experience with the DVI links because such technology is still unavailable here in Argentina. We have DVI video cards but finding a suitable DVI monitor is another (long) story.
I think that your card (that has 2 DVI ports) is initializing one port first (the primary one) and then, when windows starts, it initializes the other and outputs video from both ports.
Try connecting the monitor in the other DVI port.
If your card has a VGA output, the VGA gets initialized first.

Mag monitor doesn't display bios post


The BIOS is sending the display information to the monitor but, when you turn your PC on, the LCD will be sleeping and it will take 1~2 seconds to wake up when receiving the display signal. The monitor is working and even if the BIOS messages aren't displayed, you can still press the correct keystrokes to get to the SETUP screen or press PAUSE in the keyboard to see what's going on in the POST.
If your LCD has a bicolor LED indicating the status (Standby/On) keep looking at it, when the LCD gets the video data, the LED turns instantly from amber to Green or blue even if the screen is still black. This way you can have an idea when the LCD gets the initial video signal and to press the keys accordingly.
Your PC will also delay the video output from the secondary video card because it's detected after the onboard card.
