Asus X540S notebook PC: Is it worth putting a ssd or sshd in this laptop to speed it up?

Tue, 22 May 2018 15:13:51 -0700

I have this laptop and it has a celeron 1.6ghz duel core processor and 4GB of ram that’s not upgradable. It has a 500GB 5400 rpm hard drive. I haven’t tested the hard drive speed yet but it’s already slow. I’m thinking to put macOS on it. Will 4GB and a 250GB SSD be enough for Mac to run?

Asus X540S notebook PC: Touchpad Unrecognizable by Laptop After Clean Install

Fri, 07 Aug 2020 05:20:00 -0700

Hi all,

My mom's laptop (Asus x540s) had a bsod that I worked out to be a dead/corrupted hard drive. I installed a new SSD to replace the HDD and reinstalled Win10, but from the get go in setup, I had no access to the touchpad.

The touchpad doesn't appear in Device Manager, the only thing there is an I2C HID Device that has a warning on saying "The device cannot start. Code 10. A request for the HID descriptor failed".

I've done a lot of research and asked around but no solution has been found yet. So far I have: reinstalled Windows multiple times; replaced the touchpad and cable with new ones; installed every driver, software, chipset, and BIOS on the ASUS support page and in different orders as well as older versions of the major ones; installed generic touchpad drivers for all major manufacturers (later figured out it's made by ELAN), then tried multiple ELAN drivers; downloaded a USB run Linux distro to try to get access to the touchpad sans-Windows; enabled and disabled the touchpad setting in the BIOS; uninstalling the I2C HID Driver; used the keyboard control to turn the touchpad on/off; and other random suggestions from around the web.

Any help you can provide would be greatly appreciated, thanks!

Asus X540S notebook PC: How to replace fan

Fri, 20 Sep 2019 04:51:31 -0700

My laptop kept shutting off so I opened it up and seen that the wires are broken, I think from overheating? The red one connecting the fan is completely split in half, all the rest just look like the outside covering has melted. I put the laptop back together & now it smells like burnt plastic. I can buy a replacement fan but just don’t know how to replace it & don’t wanna ruin it more than it is. Please help. Thanks.

Asus X540S notebook PC: Asus x540LA Keyboard problem

Thu, 14 Feb 2019 15:31:06 -0700

Hello, I would appreciate your help with the following topic.

After a fall of my laptop Asus x540LA stopped working the following keys:

D, pause, imp pant, ¡, delete, enter, '

The other keys if they work ...

Believing that it could be a keyboard problem, I changed it to a new one, but the problem persists in the same keys. What could be the problem?

*I try in BIOS and it doesnt work

*With external keyboard there are no problems
