This is the most tasteless issue experienced by most of the laptop users.
You may name the above issue in separate ways such as blank screen on my notebook, no display in my laptop, notebook does not boot, laptop will not start, laptop does not turn on, no power in laptop or no post in my laptop.
The above issue is likely to occur when one of these happens:
A/C adapter does not function
Problem with Ram
Battery does not work
Hard disk failure
Corrupted system files
Display drivers not functioning properly
Finally, malfunctioning of display card
Troubleshooting
You can troubleshoot the issue or repair the laptop by following the below steps:
1. Check the display
You can check if the issue is with the display of your notebook Lcd or Tft display. You can do this by connecting external display and if you are able to get display on external display gadget then it is confirmed that it is the Lcd or the Tft display that has to be repaired.
Sometimes the corrupted display drivers might be the cause for the problem of not getting the display on your notebook or displaying blank screen on your laptop.
We can try to resolve the issue by updating or reinstalling the display drivers and you will have to check the website of your notebook constructor for the updated display drivers and if the latest version of display drivers are available then please modernize the drivers by installing them or modernize the same from gadget employer (Right click My Computer and settle on Properties and settle on Hardware tab and click on the choice gadget Manager). You can modernize the drivers by increasing the display adapters and right clicking on Intel Chipset family and selecting the choice "Update drivers".
You can sometimes fix the issue by reinstalling the drivers. You can reinstall the display drivers in separate ways, such as you can install the drivers from the Operating system Cd or rescue discs that come with your notebook or from the rescue partition gift in the system.
Even check with the constructor website if there is any latest Bios available for your notebook model, please modernize even your Bios.
Be Cautious while updating Bios as if not updated properly or if you downgrade the Bios or install a lower version of it, then this will make your laptop to not work for ever and also the Bios for 32bit system differs from that of 64bit.
If there is no display even on external monitor then the issue is with the graphic adapter malfunction of your notebook and needs to be replaced.
2. Checking the A/C adapter
(Ensure that the power outlet you are using is in working condition)
Remove the A/C adapter which is linked to the notebook.
Detach the external devices (quick dock, surge connector, etc) attached to notebook.
Now, take off the battery from the notebook.
Press the power slider or the power button for 25 - 35 seconds to discharge the static charges that might have stored in the laptop.
(With the continued usage of the laptop, some static charges tend to stay in the notebook and these static charges do not allow the laptop to function normally.)
You can now reattach the A/C adapter. (We are running the laptop only on A/C power and not using the battery)
Turn on the notebook.
If the laptop does not turn on now, check the power Led of the laptop.
If the Led is off or there is no light coming out, then the problem is mostly with the A/C adapter which is not working.
3. Testing the Battery
Again, the course remains practically the same as that of A/C adapter with only few miniature changes.
1. Take out the Ac Adapter.
2. Disconnecting the external devices attached to notebook.
3. take off the Battery.
4. Press the Power button for about 25 - 35 seconds to take off any static charges.
5. Reset the battery (We are running the laptop now only with the battery and not using the A/C adapter in this case).
6. Turn on the notebook and check if it powers up.
If the notebook does not power on, then the problem is with the battery. We can try to fix the issue by performing battery calibration.
Procedure to calibrate your laptop:
Shut down your notebook
Connect the A/C adapter and charge the laptop until the battery is thoroughly charged. Some laptops do not show any color after it is charged thoroughly while the other notebooks show green or other color.
Restart your notebook now.
Press F8 or other key to boot into safe mode.
Now disconnect the A/C power and allow your battery to discharge thoroughly until notebook turns off. This completes the process of battery calibration for the laptop.
4. Check the Ram
If there is light or Led is on but if the laptop does not turn on try by removing and reinstalling the Ram.
This course has to be done safely and gently.
While checking for the cause of the problem, use only Ram that came with your laptop and if you have installed a Ram that you have brought it separately please take off it as this will let us know where the exact problem lies since if you are using a Ram that is not compatible with the notebook, you may over these type of issues.
Note: To take off Ram or battery from your notebook, corollary the steps in the manuals of your laptop model as the steps differ for each model.
Also you may taste booting or no boot issues with your notebook when you have installed a memory module (Ram) that is incompatible with your laptop computer. Inserting a Ram each of same capacity instead of a particular Ram of high capacity would resolve the issue if you are upgrading your Ram.
5. Testing the hard disk
You may also try removing and reinstalling the hard disk as crashed hard disk can be one of the reasons for the notebook to turn on. We even have "hard disk self - test" choice in positive notebooks where these process tests if the hard disk is working or if it does not.
6. Corrupted system files
Laptop may not turn on properly or boot into windows if the system files are corrupted, the best way to fix this issue would be reinstall the operating system using rescue discs or performing Startup Repair.
