Power button not working after BIOS chip replacement

Hi

I have just replaced my BIOS chip in 840 G3 (dreaded forgotten BIOS password). After mounting the new chip, I reassembled as usual, but there is absolutely no response from the power button. I replaced chip the usual way with a 400C heat gun and I believe it went well.

Any ideas appreciated

Thanks

If you haven't already, try reseating any connectors inside the device to ensure that everything is plugged in properly.
