Why does my laptop make bleeping sounds at sporadic intervals?

I see from your other threads you have sabotaged your Laptop by doing a so-called "clean install".

Laptops are rather one off MOBOs and hardware and have system drivers which are now likely to be missing. They do not always appear in the Device Manager.

The bad state as shown by your Reliability Monitor just demonstrates this.

In view of that there is no point in any comments, until you restore it to the original bought state.
By all means uninstall some manufacturers stuff, but retain essential stuff.

Your assumption is wrong.

My laptop was not sabotaged by doing a clean install. It was done by a computer repair company in May 2021, and unlike a consumer like myself, they run the various expensive professional benchmark and diagnostics tests that a typical consumer would not have access to, to make sure the computer is in functional (or fit for purpose) order before marking the repair as complete.

You are assuming that this bad state is self inflicted. When I paid for my laptop in October 2020 brand new, and took it out of the box, this same bad state of which you speak of, it still existed back then. You can't claim a clean install sabotaged my computer if the same situation happened after buying it brand new from a department store (ie. Argos).

When I got my laptop repaired in May 2021 they wiped out the entire computer and re-installed windows. So the "original brought state" of which you speak of, that already happened last month.

New in October 2020 - made during lockdown 1?! I hope it wasn't a faulty one. So you are under manufacturer guarantee still. Did the technicians who did the repairs do it under guarantee as part of the Acer guarantee?

If it has indeed had a clean install (by that meaning installing Windows 10 on its own, rather than the manufacturer reset to factory settings) then you will know as you can see whether or not you still have a recovery drive.

If it actually has had a full clean install of Windows 10 alone, then it might indeed be an idea to restore to manufacturer factory settings, do all Windows updates, then add any programs you had before. (Before doing this you need to virus scan and then back up all personal files - documents, photos, videos, downloads, anything on the desktop - to an external hard drive - just copy and paste them over. Also export your bookmarks and copy that over to the external hard drive (so you can reinstall bookmarks).

If you can't restore to factory settings because the recovery drive is gone after clean install, then Acer will be able to provide you with either a disc or usb to restore the computer to factory settings. I had to do this once with Sony - who charged about £30 but not all manufacturers will charge for it.

There is no recovery drive now and there was none when I brought the laptop. However there is a recovery partition.



My laptop insurance isn't provided by Acer or any company associated with Acer, it's provided by Domestic and General which has a partnership with Argos.

What is manufacturer factory settings? A clean install already happened so it should have already been back to factory settings. If you're asking whether I have an OEM version of windows (that would come with the computer manufacturer's software, drivers and settings pre-installed), then no I don't, because the Acer logo and word is not visible in the about page in settings.

The repair company that the laptop insurance uses, they replaced an OEM windows with a retail windows.

Ok. This is the manual for your laptop - from the Acer support page for your model. Under Recovery on page 18, it mentions Acer Care centre where you can make your own recovery disc or usb. Is Acer Care Centre still installed? That disc or usb would allow you to reset to original factory settings with all software and drivers etc. If it was an actual full clean install done recently, then Acer Care centre is not likely to be there and you'd then have to contact Acer to supply a recovery disc. Otherwise they just say use Windows reset, but that isn't always sufficient IMO. Either a factory reset or clean install works better. In your case a factory reset is probably the way to go. And that wouldn't invalidate insurance.

Before doing that though, run a virus scan and then back up all personal files to an external hard drive. Documents, photos, videos, downloads, and docs on the desktop etc. And export bookmarks and copy that exported file to the external drive too (so bookmarks can be reinstalled as before). Make a note of any activation codes for programs you've bought or installed (although that is often supplied via email anyway these days).

Then after restoring, all you'd need to do is - Windows updates until finished, reinstall any programs and reinstall personal files from the external hard drive.

In terms of pre-installed software, it can be annoying when there things you don't want instaled, but these days I think there is a lot less "bloatware" and many manufacturer installed programs can be useful - uninstalling one may affect others working correctly. Probably best to only uninstall trial software - eg trial for antivirus etc and not any other preinstalled software.

Son had a new PC recently - HP. Quite a bit of HP software installed but we just left it as it does no harm. Only thing I uninstalled was the McAfee trial antivirus and trial of MS Office (already had a copy).

Resetting to original factory settings will give you the chance to see if that issue still occurs or not. If it does, it's a hardware issue, not a software issue. And could possibly still be a dud cmos battery maybe. One step at a time.

I've found the answer due to this wikipedia page about circular buffers.

Look at the gif animation with the caption. I know nothing about hardware, circuits and processors so I won't try to simplify it as I'll probably use the wrong terminology and get things mixed up in a misleading way.
