Re: Lenovo y540-17IRH IT8226e-192
Eventually it worked without any issues. Note: This SIO doesn't need programming. I think all Lenovo ITE SIOs don't need programming. It didn't work after replacing SIO because the power ic was faulty as well. I was confused because power ic was making 3v3 and 5v alw, 3.3 was present at power button, but I was not sure if this SIO requires programming. In my country SIO cost is around 16 us$. By the way does anyone know if SIO MEC 1515 NB programmable or not. Thanks in advanceLeave a comment:

Re: Lenovo y540-17IRH IT8226e-192
In my case I accidentally shorted adapter I'd pin with 20v. Which shorted sio internally due to which power ic started getting heated. I replaced the sio chip with the same number but now laptop is no power no charging, not sure if sio needs internal ec rom reprogramming. Someone in above replies mentioned that this Lenovo Ite SIO doesn't need programming. Please suggest. Edit: thanks for reply. If PCH is faulty then atleast red led on DC jack should be on as soon as the adapter is connected and charging circuit should work. ThanksLeave a comment:

Re: Sony mbx-224 conversion to uma
I tried but didn't work, however its possible to replace the graphics chip that fails quite often with the chip which is reliable by changing some parts. The video in non English language available on You Tube for the same. Again its not viable.

Re: Asus X541NA power issue
I have 2 slightly different Asus boards with same issue. First mosfet stopped 19v because it was not getting 24v on its gate because second mosfet the small one had its gate shorted. Both boards have different number markings. And no datasheets available for both. It seems both are n type mosfets so I tried many different n type mosfets on both board but no battery charging. R everything else works fine. Any idea? ThanksLeave a comment:

Re: Hyundai X93W - Dark after 4 secs
Thank you very much, it worked on my HCL brand 18.5 lcd monitor.....Another solution I had, was placing 2 universal ccfl inverters to operate ccfl tubes. But universal inverters are not a reliable solution.Leave a comment:
