My led indicators for caps lock num lock etc not workinh in my lenovo G570 laptop


Hi, If you are using a keyboard that is wireless im sure you just have to change the battery on the keyboard.
However if the keyboard is connected to your CPU, then depending on your keyboard model, you may have to turn F LOCK (F Lock Light on) to access system key commands if they are labeled on the front of the keys, such as num lock , scroll lock and print screen.When you click on the Flock, the lights are either supoosed to click on or off.
view the keyboard status lights by using the On Screen Display (OSD) option, Ensure you download the software ,
from your start menu do a search for your keyboard, on th key tabs setting,
its important to make sure that the correct model number is entered,
double click on the light you wish to change, in the Reassign a Key wizard,
clear the Displays (key name) status on the screen check box to disable the on-screen display, or select it so that a check mark is in the box to enable it, and then click Finish.
HOPE THIS HELPS.

Does not boot up, fans start, internet plugs light, clicks on and off.....seems this is a common problem for these machines, what is the fix?


Instructions
  1. When you press the Power button to start the boot process, the LED lights glow while the computer verifies that there is sufficient electrical power to activate the hardware.

    Effect & Solution: When you press the power button, the LED lights on the computer do not glow or the LEDs blink briefly and then stop. There is no sound of the fan or hard drive spinning, and the screen remains blank. The computer will not start if there is insufficient battery or AC adapter power.
  2. The BIOS queries various hardware components used for the startup boot process.

    Effect & Solution: When you press the power button, the LEDs glow but there is no fan or hard drive sound. The LEDs may glow briefly and then go out.

    Or

    The LED lights blink, stop, and then blink a second or third time, but there is no sound from the computer and the screen remains blank. The sequence of the blinking lights indicates a specific error code.

    Or

    A series of beeping tones is heard. The sequence of beeping tones indicate a specific error code.

    If a hardware component has recently been replaced, or if the PC has been jarred or shaken, there may be a loose connection to the memory chips or hard drive which prevents the computer from starting.
  3. The BIOS loads the basic input (keyboard) and output (advanced LEDs / display screen / boot drives) devices into memory.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, but then the boot process stops and a black screen - with an error message - displays.

    The boot check has detected a communication error or conflict with a hardware component that must be corrected.
  4. The BIOS loads the Windows operating system and starts the services that allow low-level control of all of the background operations.

    Effect & Solution: When you press the power button, the LEDs glow, the fan or hard drive sounds, are heard, the HP or Compaq Logo displays on a black screen, but then the boot process stops and a blue screen - with an error message - displays.

    The boot check has detected a hardware driver error or a software conflict that must be corrected.
  5. Control is transferred to the Windows loader to initiate the display of the advanced settings in the Windows environment.

    The Windows logo displays during this step.

    Effect & Solution: When you press the power button, the computer performs all the steps in the boot process, but after the Windows Logo displays, the moving Windows progress bar or the rotating cursor stops moving and the boot process stops.

    An error message may display on a screen with the Windows logo. In some instances, there is no specific error message.

    Or

    A black screen appears and the computer attempts to restart.

    The Windows self-check has detected a software conflict that must be corrected.

Gateway 3200S. will not begin to power up. a green led is on at the top of the mainboard. that is the only indicator of power.


Dear Rythmickarma,
As you said the main power LED seems to be glowing but the system is not powering on... so there are few things to check here:
  1. Remove all other connections apart from Power supply, keyboard, mouse and monitor and see if that makes any difference.
  2. When the computer normally boots up there is a POST check Beep sound from CPU .. do you here any beep?
  3. When you tap on numlock key on your keyboard, do you see numlock LED toggle between ON and OFF state?
  4. Is there any signal on monitor .. When disconnected from the CPU, the monitor should show Self test signal .. does it happen?
  5. Open the chassis and check if you can feel the spinning of Hard drive...
  6. Remove the power supply cord from the back of the computer and press and hold the power button for few seconds .. this would drain the accumulated power from the CPU components .. now reconnect the power supply and see if that makes any difference..
Please try the above steps and let me know. Hope that helps.

Regards,
Srinivas

AsRock Motherboard won't boot. Need Advice.


Here's the solution!

Check if NUM lock glows if tapped on the Keyboard ::

Yes - If your Power LED is blinking change the SMPS, if it is Solid, change the I/O cables or RAM or Display Adaptr - whichever you think the problem to be.

N0 - Change the board.

PS. If processor is the problem, CPU fans won't spin in the first place.

Problem with GA 8LD533


There are a few easy fixes for this, first,

Clear the CMOS (Unplug the power cord, remove the battery, and (if it's an option) move the jumper J1 (it has three pins, the jumper covers two, move it to cover the other one), unplug everything external from the motherboard apart from the PSU and power switch and speaker, replace battery, powercord, and jp1, power up - what happens?
