The fan usually balances over time, as you put it out of balance with hitting it with that high pressurized air, if it works ok and there are no gpu temp hikes, then just leave it as its probably ok and there is nothing wrong.

You have probably slightly bent the gpu fan shaft with the compressed air if you directed the air straight onto the fan, with cleaning fans you only use a fine brush not compressed air, as compressed air damages the fan shafts and that is what you must have done, if its not too bad then just leave it, if it gets louder then change the gpu fan. Also if you need the exact Acer part number for this gpu fan, next time list what laptop model you have.

Hi hdara012,

On an 8‑year‑old laptop like your Spin 7, the battery is by far the most likely cause of the symptoms you describe — even if it was replaced once before. Lithium‑ion packs degrade over time, and a low‑quality or poorly stored replacement can fail in a year or less.

If the laptop runs normally on AC power but shuts off instantly when unplugged, that’s a textbook sign the battery is no longer delivering power. “No battery detected” after only a year strongly suggests the replacement pack itself has failed, not the motherboard.

Next steps:

1. Test on AC power — if stable, the mainboard power delivery is likely fine.
2. Source a genuine Acer battery or a high‑quality compatible from a reputable supplier.
3. Install and retest before considering any board‑level repairs.

Motherboard charging faults are possible, but they’re far less common than simple battery failure on a system of this age. Always rule out the battery first — it’s cheaper, faster, and in most cases, the real culprit.

Most symptoms of a battery not charging is from either a blown EC chip that doesn't communicate with the battery board or a blown BQ chip or the laptops main power rail chips like a mosfet or a capacitor are shorted. All these aspects of your Acer Spin 7 Laptop 2017 which is an 8 year old laptop could have a shorted component that you need to take your laptop to an experienced tech that can pinpoint the exact problem and fix your laptop..

First try and do a hard reset and see if the EC chip and bios chip are not frozen and will reset, for a hard reset you need to take the main battery out then disconnect the bios battery plug and short its +&- pins at the mobo plug to reset CMOS, then take the ram out and leave the laptop to reset for at least 30min, then reconnect everything and if you have 2x ram modules only connect one and alternate the two modules, and see if its not a faulty ram that is causing this boot problem.

If this doesn't work then you need to do the above ands take your laptop to an experience d tech that can fix your laptop. Good luck and hope this helps you out.
