T590 - new AC Adapter causes touchpad to lag

2019-12-06, 15:13 PM

Hello,

I've had this problem for a while now, where apparently randomly the touchpad would start working slow.

Movement would overall seem slower, and it would more often than not miss taps, so to click reliably i would have to use the physical buttons.

I tried messing with bios power settings but they would bring no change.

The problem only happens when plugged in with an AC adapter, one i bought on amazon to bring with me while working, while the original one that came with the laptop i'd leave at home.

I haven't noticed any other difference from normal behavior, other than the touchpad lag.

The one I bought is *supposedly* original, from Lenovo's amazon page, but has a different model ID from the one in the laptop packaging.

 

 

Here are the infos on both adapters:

AC Adapter from amazon (CAUSES THE PROBLEM):
-------------------------------------------------
MODEL:      ADLX65YCC3A
LENOVO PN:  SA10M13950      FRU PN: 01FR026
INPUT:      100-240V~1.8A 50-60Hz
OUTPUT:     20V--3.25A/15V--3A/9V--2A/5V--2A

MFG DATE:2019/09

REV:500
-------------------------------------------------

Original one (DOESN'T cause the problem):
-------------------------------------------------
MODEL:      ADLX65YDC3D
LENOVO PN:  SA10R16870      FRU PN: 02DL124
INPUT:      100-240V~1.8A 50-60Hz
OUTPUT:     20V--3.25A/15V--3A/9V--2A/5V--2A

Anyone has any idea why that may be / if it can be fixed / if it seems like the new adapter is somehow defective / if it might come down to a bios update?

I dont really know enough about hardware to correlate a different adapter to a touchpad problem, so any idea is welcome.

Other than the obvious "get a new adapter with the same model this time", which i'd rather avoid if possible.

 

Thanks for any help.
