After ram upgrade Acer d255 not booting up

[Abélard]

I have Acer 5520G which is installed with the Windows 7 operating system on it. I recently upgraded my ram in Acer D255 Dual Core. Now when I press the power button, then all LEDs are ON in the laptop, but laptop will not start. Only the screen is blank and has not been any commotion in high definition. I cannot understand if the problem I am facing is due to defective hardware or software? Suggest some solutions, if anyone has had problems with the starter. Thanks in advance.

I think the HDD of the laptop has gone bad due to which it is not able to load the operating system. If the hard drive of the computer develops a fault then the laptop will not be able to start with the OS. There are many HDD analytical tools obtainable which can be used to find if there are any issues with the HDD. Download one such diagnostic tool and run all its tests on the hard drive. If there are any faults with the hard drive which cannot be solved then you will have to replace the hard drive

There is CMOS battery which is in charge for retaining all the adjustments desired to boot the computer. Uncase the laptop and find the battery on the motherboard of the laptop. Remove the battery and test the voltage across the battery with a multimeter. The voltage should be amid 2.5 volts and 3 volts. If the battery voltage is beneath 2.5 volts, replace the battery and see if the laptop is started or not.
