We'll you can do that. But you would have to open up your laptop to replace the current keyboard with a new one having backlight. Here is a link if you are ready to do so. https://laptopschamp.com/can-you-add-backlit-keyboard-to-laptop/

I just wanted to share some more interesting finding which i got while further testing. There was a presence of follow voltage (ac) on the psu case under different conditions (Ground was insulated just for testing purpose) 1: 25-35 V when the psu is turned off(by flipping the switch behind the psu) but is plugged to the wall outlet. 2:100-105v when the psu is turned on . 3:111-120v when there is an extra load added, in this case i used a neon tested to add a tiny load. Can someone tell me what's going on. My knowledge in electrical and electronics is not that great. Thanks.

I checked that to see if any voltage was coming from the earthing port but no. There was voltage on the earthing port only when the psu was connect to the outlet.

Well i didn't mean that it was unplugged from the outlet. The PSU was plugged on to the outlet without ground (only for testing or else i would have used a grounded outlet) and it showed voltage on the body even when the "switch on the back of the psu was off"

Sorry. I ment the TX-M with the 80+ gold standard.

Well then I'll buy the TX. Thankyou so much.

Are any of these good https://mdcomputers.in/thermaltake-smart-bx1-rgb-650w-80-plus-bronze-ps-spr-0650nhsabe-1.html https://www.vedantcomputers.com/cooler master-masterwatt-650w-650-watt 80-plus-bronze-certified-semi-fan-less-modular?search=650 watt&description=true https://www.vedantcomputers.com/corsair-cx-series-cx650m-650-watt-80-plus-bronge-certified-psu?search=650 watt&description=true

Well thanks for the time. But the price is the issue here. I am trying to stay below 120usd(about 8000rupee) because i don't want too spend to much on PSUs. The Corsair tx 550 will be fine, but i presently have ah 550 watt one (but faulty) and I'm not sure if 550 is enough for an rx5700 , ryzen 5 2600 on a b450 board And i dont know if gold and bronze makes much of a difference. Does it? If bronze standard is fine i have many options Thanks

Thanks for the link. The list says Antec earthwatts pro gold are of poor quality and try to avoid it so i probably should. Or did i interpret it wrongly?

Yes i can give you links of some store which i usually do pc part purchases. https://www.vedantcomputers.com https://mdcomputers.in https://www.primeabgb.com/ It would be really helpful if you could fine me something good. And im planning to buy a rx 5700 gpu

Hai . I was planning on buying a new power supply and i wanted a 650 watt unit. I came accross this "Antec Earthwatts Gold Pro Series EA650G Pro 650W PLUS GOLD Certified Modular PSU" and it seems to be a good deal. I couldn't find much info about quality of these units. Does anyone know about them. Are they good? Thanks

The psu was disconnected from the motherboard and rest of the components. So that i could test what's faulty. I live in India so its 230v ac.I just tested to see if there is any presence of current on the ground from any other electronic component in my house (without plugin in the psu) and there was none. Then i connected the PSU in a port with proper grounding and checked the adjacent ground port to see if there was any current and the tester thingy lights up. Doesn't that mean the psu is leaking somewhere and is being discharged through the ground. I know this is kinda messed up. But i have no where else to ask than the internet. I'm replacing the psu anyway but i just wanted to know what's causing this, because i think its a good practice as an engineer student. Thanks for you time and knowledge ?.

Well i don't know if its mains(ac) or dc from the output of psu. Because i don't have any special equipment to check so. But as the voltage is still there even when its turned off its probably mains(ac). I used a Multimeter touched one proble to the psu and other to the ground on the outlet and it showed 17 v (on ac settings)which makes no sense ( mybe i damage the multimeter doing so). And that image where the tester lights up was done by covering the ground pin with insulation tape. The tester doesn't light up when there proper grounding. My breaker trips if i accidentally touches the psu and i get a biting shock. So i was wearing gloves when doing the test. I also opened up the PSU to check if the mains input is touching the casing (yes i know its dangerous so i had made sure I'm properly insulated and discharged the capacitors before messing further with the psu), but its seems to be isolated by a plastic sheet underneath. Everything i find while trying to solve this, just makes the matter more complicated ?

I would definitely ground it. But u wasn't sure is psu were supposed to do so and should i replace it. The image just shows the tester lighting up even when the psu isn't turned on with jumpers.

Yah, its work fine when grounded. I noticed it when i moved the pc to another outlet which doesn't have ground.
