Updated RAM and no boot up at all but made a mistake! Predator Helios 300 PH315 54.

Hello!

I bought some Crucial 3200 2x16gb (32gb) to update my Acer Predator Helios 300 PH315 54.

I installed the RAM. However, I thought I had disconnected the battery - I didn't. Turns out I disconnected the keyboard wire which is right next to the +- of the battery instead.

I then went to boot up the laptop after plugging back in the keyboard wire thinking it was the battery (back to normal). Nothing happens.

After doing some further research at this point, resetting the CMOS CR2032 was the next step to try. On attempting that, I broke the plastic connector. So I have order a new CMOS CR2032.

As you can tell I have gone down a bit of a rabbit hole. Has anybody got advice from this stage on?

I am also worried when I disconnected the keyboard wire underneath the battery I may have scratched/damaged the pin, but this would not have resulted in a no boot I guess.

Really appreciate any reply!

Thanks,

[Edited the thread to add model number to the title]

    Inserting the ram while the battery is plugged in does not cause any damage and/or a laptop to not boot or do anything. Upgrading a laptop to different ram and different capacity, you need to allow the bios to reset and adjust to the new ram.

    After you get the new bios battery, shot its +&- pins at the mobo plug to reset CMOS and make sure that you connect the battery and the keyboard plugs properly (see caption below). Then boot the laptop as the boot could take 2-3 minutes to boot the laptop as the bios has to reset. Good luck and hope this helps you out.

    Here are all the PH315-54 connectors of your laptop for future reference so that you don't make that mistake again😁

    StevenGen thank you for replying!

    When you say  ''Then boot the laptop as the boot could take 2-3 minutes to boot the laptop as the bios has to reset.'' do you mean hold the power button for 2-3 mins?

    Fortunately, I have the new bios arriving tomorrow. Will update thread after.

    Thank you again for the image diagram, I had seen that earlier on in the day but could not find it for the life of me! (F) Keyboard FPC is the one I am worried I have scratched. But again that should have no impact for boot up. Silly me!

    Thanks,

    Joe

    No, when the new bios battery arrives and before you connect the new bios battery, disconnect the adapter and the main battery, take the 2x ram modules out, then shot the +&- bios battery plug with a metal screwdriver or metal tweezers monetarily at the mobo plug to reset the CMOS of the mobo, then wait 15 min for the EC and Chipset chips to reset and then reconnect everything, and once you reboot the laptop you need to wait 2-3 minutes for the bios to reset and recognize the new Crucial bigger capacity ram, that is what I meant as the laptop should boot and work 100%. Good luck.

    Thanks again StevenGen. I will follow your steps tomorrow and update. I guess this was my initial issue in my laptop not turning on by pressing the power for a few seconds the first time. I just need to make sure when I connect the bios battery tomorrow that the polarity of the bios is the same as before. Luckily I took a picture.

    Thanks,

    Joe

    Hi @StevenGen , I thought I would drop an update here.

    Unfortunately I tried the above and this didn't work. No light even comes on when I attach the charger either.

    Thanks,

    Joe
