Question about IBM ThinkPad T42 Notebook

Screen Don't Comes On Anymore

I can hear the fan spinning, the power light and the light that shapes like a Z in a circle is on but there is no signal on the screen, when I press the power button the computer turns off, when I press it again it turns back on but no signal on the screen.

Could you please suggest what could be the cause of the problem and what could the solution be.

Thank You,

"SHA"

Have you tried plugging an external monitor into the VGA connector on the back? This would narrow down the problem to either the video card/motherboard or the LCD display itself.

There are several possible defects- as above, the display, motherboard component, video section.

Also, first check the LCD/CRT switching function. On many laptops, there is a function (FN) key which is pressed at the same time as one of the number/function keys (the uppermost row of keys), and this combo will switch display from LCD to CRT & both.

Error why coming


Can you hear any fan or drive sounds? If you don't hear anything at all when you try to turn the laptop on, no little LED's light up, the problem almost certainly isn't related to the hard drive. So if you don't have a live screen, start with the LCD troubleshooting flowchart, and if you don't have any activity at all, start with the power troubleshooting flowchart. Even if the hard drive has failed at the electro/mechanical level and won't spin up, this wont prevent the LED's on the laptop from lighting up, or the LCD from displaying the BIOS information and complaining about the lack of a boot device.

Comp.will not boot starts screen no signal goes off


When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.

When i turn the power on, 3 beeps play, the fan runs and the power light comes on, but nothing else


Hearing ONE beep is normal, and a signal that the computer hardware is OK.

Hearing THREE beeps is a signal that something is wrong:
* burnt-out CPU,
* one of the fans is not spinning (clogged?) or spinning too slowly (about to seize-up),
* one of the RAM chips is defective
* the video-card is not working

If there is more than one RAM stick, remove all but one stick, and start it up, to see if it starts.

Check that the fans are spinning freely.

  1. Get a clear view of the sky and then turn off the unit and then power on again.
  2. Once the unit is on and you see the street display tap on the signal icon on the screen.
  3. You will see a half globe with horizontal signal color orange and wait for at least 5 full green signal and then close that page.
  4. Once your in the sreet display you will see tsignal strength on the screen.

Desktop will not boot into bios No Usb power;monitor ''No Signal''


Your problem is the memory . YOu have to put off the pc and remove the memory card in the slot. Then clean the silver pins in your memory with a rubber eraser. Put it back and see if the BIOS will be prompted on the screen , if not you have to replace the memory.

Screen does not turn on but green light is on.


Green light indicates the monitor is getting power. Nothing coming up on the screen indicates, No Signal.

No signal from the computer. This means the computer itself isn't working.

A bad power supply in the computer can cause this. A bad power supply is the leading cause of desktop computer failure. It is replaceable, and can be done by the owner relatively easy.

You may have a computer tower that the Power light comes on, you hear fan/s spinning, (Including the Power Supply fan), and it sounds like the harddrive is running.

ALL the lights in your computer use less than 1 Watt.
EACH fan uses 2 to 3 Watts.
A harddrive sitting there spinning in an endless loop, consumes about 2 to 3 Watts.

A Processor uses 51 to 125 Watts. Depends on what Processor it is.

A weak Power Supply will have enough power for lights, fans, and that harddrive sitting there spinning.
It won't have enough power to turn on the Processor.

[No processor operating, then the harddrive sits there spinning in an endless loop, because there is no processor to find the boot sector]

For a test, connect your monitor to a know good computer. See if it works.
Now connect that other monitor to your computer.

Won't boot. Power light on, No Video Signal message


It's also possible that your operating system has become corrupted. See if there is enough time to boot into safe mode, or choose a boot option to go into the recovery partition.

Have you made any recent hardware or software modifications?

Green light comes on, but thats it. Black screen, no audio. Hear the disc spin but thats it.


I would reccomend checking both the TV's input jacks and the Xbox's output slot. If you got a new AV cable, then the odds that that cable are faulty are slim.

I found a microsoft troubleshooting Web Article that may help you solve your problem.
