Lenovo Y500 Idea Pad Power Adapter replacement options?

2016-05-17, 22:15 PM

My power adapter to my Y500 Idea pad is messed up. The wiring inside must have gotten damaged somehow and is now faulty. It only charges my laptops when angle in certain positions, or goes in and out. It's the 170W AC adapter one, but is there really a difference in using one of the small Wattage Adapters? The 170W one is just way out of price-range for me so I'm looking for one of the cheaper versions. I found one online that is "Y500 AC Adapter 90Watt 19V 4.74A". Would that work with my laptop? 


I don't understand how different wattages affect my laptop (I'm assuming it affects charging time) so any help is appreciated. I generally keep my laptop plugged in with the battery removed, so I don't have to worry too much about charging the battery, if that's any help.

Thank you!

Hi Veemo , 


Welcome to the Community Forums. 


To best illustrate using lower wattage adapter, imagine a lower wattage bulb than a higher one lit. 

It would work but may not work for full functional performance and may even shut down if the requirement cannot reach such need like the GPU and processor.


You may charge the battery with it but to use it may result on lower performance and possible pop up messages every now and then. It can also create overheating as it would require more wattage for other device to perform .


So one a lower wattage it would be the other way around, exhausting the battery when using it then turning off to have the battery recharge again. 


Recommended part number based on the hardware manual ( page 93

120W, Liteon PA-1121-16 19.5V6.15A adapter 36002079 *

120W, Liteon PA-1121-16 19.5V6.15A adapter-CCC 36200403 *

120W, Delta ADP-120LH BA 19.5V6.15A adapter 36002031 *

120W, Delta ADP-120LH BA 19.5V6.15Aadapter-CCC 36200400 *

170W, Delta ADP-170BB B 20V8.5A adapter 36200232 *

170W, Delta 45N0111 20V8.5A adapter-CCC 36200401 *


If you usually had it plugged in with the ac adapter , for safety purpose definitely go for the genuine parts

If you just need something to use at the moment , refurbished or generic adapter just make sure that you do not leave it plugged in unsupervised .


Do you have the machine number since the manual show 120 W and what you have is 170 W?
