Is it OK to replace a laptop screen without disconnecting the battery?
This is in regards to Laptops that use the 30/40-pin LVDS connector 14” / 15.6” Screen Panel standard screens.
I have noticed that lots of Acer Laptops feature a power switch hiding under a removable cover under the laptop that is disengaged when the cover is removed. Such as the hard drive bay cover. This would make it safe to replace the screen with the internal battery still installed as power is cut to the laptop’s motherboard.
Then we have Lenovo / HP laptops 14” laptops as well. If it is a touch screen / non-standard laptop screen I always disconnect the batteries to be safe as they tend to be wired differently for the screen.
You may also be familiar with the ASUS Laptop model called F555(L) series. That one features an internal battery and most people would tend to replace the screen without removing / disconnecting the internal battery.
