Hi Sara,

It most likely means that your clutch is slipping. It means when your clutch is engaging and disengaging and no power is delivered to the wheels and as a result, the car will not move forward. In other words the revs will increase without the car accelerating. The clutch will fail due to the wear and tear and also from driving habits and driving conditions.

Hi @returntomonke ,

Do you think that it is booting into Windows?

If so try connecting an external monitor to the laptop's HDMI port (or mini DP port) and check if it shows a display or not. Don't forget to press Fn + F8 to toggle the display between the laptop screen only, the external monitor only or both on together.

If not, can you get into BIOS on startup with a display? Press F2 on startup and check

Hi @returntomonke

It seems as though it is not starting or at least not passing POST (Power On Self Test).

Not much happens until it passes POST (which doesn’t take long) so there may not be any lights except the Power light or perhaps sometimes a blinking caps lock or power light indicating a problem if it fails during POST (blink error code)

How did you reset the BIOS?

If only by disconnecting the battery and holding the Power button operated for 15 seconds then in this instance it may not have been enough to restore the BIOS to its default values.

Try a full power refresh by disconnecting the main battery and removing the motherboard so that you can remove the CMOS battery from the underside of the motherboard. Remember the orientation of the battery before removing so that you reinsert it the right way. Usually it is +ve on top

When you have the battery out, measure its voltage and if it is <2.6V DC, replace it. It looks like a CR2032 coin cell battery so it is commonly available most everywhere. Check the type number on the battery just in case it is another type. Checking the battery voltage allows enough time for the BIOS to fully reset as now there is no power at all on the motherboard.

If you haven’t got a DMM (digital mulitmeter) then allow a minute or so, before reinserting the CMOS battery to allow the BIOS to default back to its factory default settings, hopefully restoring any settings that were corrupt and preventing a normal start

Then reinsert the CMOS battery, reinstall the motherboard, reconnect the main battery, close up the laptop and try turning it on.

Here’s an image taken from a teardown video of the laptop, showing the location of the CMOS battery on the underside of the motherboard.

If it still fails after this then it is a motherboard problem

Well, it worked. The Studio 3 band I order fit perfectly on the Studio 2’s
