I have a Lenovo G505 that recently appears to have died and I can't get it to start up. I initially thought it was a bad AC adapter and replaced that, but even with a new adapter I don't get any response from the laptop.
I tried removing the battery, removing the power plug, and holding the power button for 20 seconds. Nothing changed. I tried removing the battery altogether and powering it on (thinking that it might be able to run only on AC power) but that didn't work, either.
I don't get any sort of power indicators anywhere - no LED lights, no sounds of it booting, no BIOS, nothing. It's like it's not getting any power at all. No matter how long it's hooked to the AC adapter, I press the power button and nothing happens.
Is there any further advice or anything to try, or should I just call it dead and start looking for a replacement?

Welcome to the Community Forums.
The hardware manual does offer power checkout guideline page 21.
As what you have already done with a known good charger and that the indicator lights still would not turn on with or without battery , then systemboard replacement is recommended.
It may still be worth to have it checked physically for probable issue with the DC in port for burnt or non contact cables and likewise the power board (item 3 page 81) failure before a systemboard replacement.
Hope this helps answer your query.
