Hi @no_username
If it still doesn't work try a full power refresh and check.
What can sometimes happen is that the BIOS can become corrupted preventing a normal start. Draining all the power from the motherboard causes the BIOS to default back to its factory default state.
- Disconnect the charger if connected.
- Remove the main battery from the laptop.
- Disassemble the laptop and remove the motherboard from the laptop. Then remove the RTC (Real Time Clock) coin cell battery on the underside of the motherboard. Here's a teardown video that may help. The RTC coin cell battery can be seen at 10:13 minutes into the video. When you have removed the RTC battery, measure its voltage. If it is <2.5V DC replace it. The battery model number is on the battery itself. It might be a CR2032 but double check.
- Reinsert the RTC battery (usually +ve is on top, printed on battery)
- Reassemble the laptop, reinsert the main battery, connect the charger and check if it turns on.
If it turns on OK, there may be a message about the date and time being incorrect. This is normal because the BIOS as been reset. Once you correct the date and time, the message won't appear the next time the laptop is started. Also any user defined BIOS settings that you have changed, to suit whatever operating requirements you have, will need to be changed back to what you changed them to, from their default state.

Perhaps you miss reconnecting one of the cables properly when reassembling. Do any other lights come, the fan spinning, etc.?

Only the power light on the power button and the power light on the palmrest. No CPU fan sounds, no HDD sounds, no ODD sounds.

Did it work after the "upgrading" or not?
What upgrades did you do?
Did you check that the power button board cable connection is OK?

Yes I upgraded the RAM to 12GB, made sure it was PC3-10600 or PC3-12800 which is what my CPU is compatible with. I installed a 500GB HDD hoping to install Windows 10, only to find out I couldn't turn it on. I checked my work and every cable is where it should be, nothing loose at least from what I can see.

According to what I just found out the ram for the laptop needs to be DDR3L not DDR3, so did you get PC3L-12800 or PC3 -12800?
DDR3L is dual voltage ram and will work in both 1.5V and 1.35V ram slots.
DDR3 is 1.5V working ram only and will not work in 1.35V slots.
Check what the information is that is on the ram module to see if you can find the specifications that tell you exactly what type of ram it is. Also check the originally installed ram to confirm what type of ram it is to make sure what I said is accurate about it needing to be DDR3L.
Does it turn on if you install the original ram again?
