The laptop’s power light turns on for a second or two before completely turning off. As a result, it is not turning on. I have shown it to some repair workers in my country, and they say they need to replace the motherboard to fix the issue. However, I do not trust them. Kindly provide any suggestions as to what is going on and what can be done to resolve the issue?

Hi,
Try a full power refresh and check if this works.
If it also doesn’t work then there is a motherboard problem.
Here’s the procedure:
Disconnect the charger, remove the main battery, disconnect the RTC coin cell battery and then press and hold the laptop’s Power on button for 30 seconds to drain any residual power from the laptop and also to reset the BIOS back to default settings in case it was corrupted for some reason.
Whilst the coin cell RTC battery is out if you have a DMM (digital multimeter) check the voltage of the coin cell battery. If it is <2.6V DC replace it.
Then reconnect the RTC battery, reassemble the laptop and insert the main battery.
Reconnect the charger to the laptop and turn it on.
Here’s the owner manual for the laptop. Go to p.51 to view the necessary pre-requisite steps and then the procedure to remove/replace the coin cell battery

# Is the harddrive running (can you hear any sound)? if not then, a new hardrive may be needed.

I have hardly used the laptop in the past 1-2 years, and the repair man did talk about some liquid. But, I don't recall spilling water over it. Does your website sell motherboard in case I need one?
I am a software engineer, I do not own a store. My guess is a harddrive, usually the harddrive that comes in the computers are too small, and technology keeps increasing. from Harddrives of 250 gig now you can get 1 or 2 tb. A harddrive may cost you about $60-$100 dollars and not difficult to install. Getting a manual of your laptop may help you to see what is the hardware(software) in your computer.
Would replacing the hard drive with an SSD work?
I will try removing the HDD, and then turn it on. See if that works.

a bad battery will keep a computer from starting. try powering it on with nO battery in it, just wall charger,
does it power on?

It doesn't. The power light lights for a second or two and then it is all dead.
and you removed the battery? using just wall charger?
Ya, and the same outcome.

maseeh khan verify for us that your computer is indeed a Dell Inspiron 15R 5521. Do you have a multimeter. Have you checked the power going to your computer? Have you checked your motherboard for corrosion damage and or bad components? Post some good pictures of your motherboard with your question. that way we can see what you see.
