My swift 1, sf114-34-P1DX won't turn on or off, sometimes the acer logo appears briefly then the screen goes black, the keyboard lights flash on for about 10 seconds then off for a second repeatedly.

Those symptoms are from an EC chip that is either freezing and disabling the laptop from booting or its a main power rail problem. I suggest as a first step try and do a hard reset and see if that unfreezes and properly resets this chip, as it could be that this chip needs replacing and reprograming or your SF114-34 laptop has other main power rail issues that need pinpointing by a technician.

Do a hard reset of your SF114-34 this way - Use the type of TORX screwdriver spec below to remove the 11 screws that hold the lower case.

Use a pick to pry the upper edge of lowercase open, then remove the lowercase. Then disconnect the main battery from the mainboard, then take the main battery out. Press the power key for 15 seconds to release all power to the laptop, then disconnect the RTC/BIOS battery plug from the mainboard and then short the bios batteries + & - pins plug at the mainboard (as shown by arrow below) to reset CMOS.

Leave the laptop like that for at least 30-60min so that the EC chip reset completely and then reconnect everything, as the laptop should turn on and boot properly.

Hi @sc27 ,

Given the SF114‑34‑P1DX launched in January 2021, if yours is still on its original pack, the battery could indeed be around 4½ years old now. At that age, capacity loss is expected — especially if it’s been through frequent charge cycles or stored at full charge in warm conditions.

Even if your current fault points toward EC or main power‑rail issues, an aging battery can complicate diagnostics, so it’s worth checking. If you replace it, be sure to source the correct part number for the SF114‑34 series and avoid low‑grade clones, which can cause charging or calibration faults.

Alternatively paste this in the command prompt: powercfg /batteryreport and open the report with your Edge browser, press Ctrl + P or right click and select "Print to Microsoft PDF", attach the report to your reply, type @Puraw or use "Quote" when you reply so I will get an alert.
