Lenovo IdeaPad S145: My laptop is not switching on from the power button

Sun, 23 Apr 2023 12:16:24 -0700

I used this lenovo IdeaPad s145 for about a year and one time it just couldn't switch on, I thought it was the charger so I bought another charger but it still couldn't switch on and also when you plug it in, it doesn't show the red/green light next to the power button that it's charging. Please help?

Lenovo IdeaPad S145: Lenovo Motherboard schematic/backlight fuse location

Tue, 02 Feb 2021 18:31:53 -0700

I'm looking for a schematic for the motherboard in my Lenovo 81UT003WUS. The motherboard part number is 5B20S42804. Have a no backlight situation, pretty sure it's the fuse but can't find it to check. HELP!! :) Occurred after screen replacement, which I believe was faulty. Installed screen in 2 identical laptops to troubleshoot and both now have no backlight on any screen. The screen part number is NV156FHM-N61. Thanks for any input.

P.S. Laptop does display very dim image, also works fine on external display.

Lenovo IdeaPad S145: Laptop won’t turn on after water spill.

Wed, 13 Aug 2025 01:31:25 -0700

A friend of mine accidentally dropped his water bottle into the pocket of my messenger bag where my laptop was sitting in. The laptop was in its own bag, but I only noticed that the water bottle was in my bag after 5 minutes or so. I took it out of the case and wiped the water off with a tissue paper, I turned it on and it was working quite well despite the slowness of my browser. After an hour, I closed the laptop and to go attend to some errands, after another 5 minutes, I plugged in my laptop to start working again, I booted it up and it while I was working it froze, so I shut it off and plugged it into a power source, then it stopped turning on. I then noticed that there was still some water on the power button. It’s been another hour and it still hasn’t turned on, any info that could help?
