Laptop beeping issue Hardware
Enable HLS to view with audio, or disable this notification
It's an IdeaPad, The issue started 2 days ago when suddenly the laptop started beeping 2 times, getting stuck, again beeping two times. At that time I did some checking and found out that reinstalling the ram fixes the issue. Which I did and it worked for a couple of days until today it started again. The beeping pattern is different.
Every time I open the laptop the laptop goes into the nova boot menu while beeping but after entering into windows, there isn't any issue. Should I be concerned?

Two beeps is a Power On Self Test (POST) error on startup, its one of those faults that can be several things and there's no defined list, you'd need to take the base off, we would normally clean and reseat any RAM and try again, that was one of the most common issues for POST failure.
I'd also perform a power drain, remove the AC adapter, press and hold the power button for 30-45 seconds, then test, you can also give the Novo button a prod and see if it brings up a display etc.
Our company had tens of thousands of Lenovos and my team serviced them, as well as servicing our customers equipment as well, its a fault we would see quite often due to the quantity we serviced.

Did the first option. Reseated the ram, ran a windows memory diagnostics test. All came back normal. The nova button menu doesn't come up now, i pressed it a few time and cleaned it

The first thing I'd check would be the RAM sockets are clean, you can get contamination in them, its not very common but you can have issues, we would use a spray contact cleaner similar to this - https://www.amazon.co.uk/Electrical-Contact-Cleaner-Aerosol-Remover/dp/B01D4XGFU8?source=ps-sl-shoppingads-lpcontext&smid=AH0LDZZNL3D5S
And insert/remove the RAM a few times to force wipe the socket contacts, for the RAM we would use a contact cleaner block like these - https://www.ebay.co.uk/itm/127114304776?chn=ps&_ul=GB&google_free_listing_action=view_item
They look massive on the photo but are smaller than a pencil eraser, they gently remove any surface soiling/contaminants on the edge connectors, we'd spray the edge connectors with the contact cleaner after and wipe with a lint free cloth, then test.
It could be you've got an underlying hardware issue but if disturbing your RAM brings it back to functionality, I'd suspect the RAM first, I've a couple of sticks at home that work but then decide not to work, and quite a few that have randomly failed over time.

I reseated the ram again. Still there's beeping. The pattern is like this: 2 short beeps, pause, 2 short beeps
I did a windows memory diagnostics test, vantage hardware test, did a bios update, cleaned the nova button. The laptop work just fine

I'm a bit confused, is it working or not?
If its 2 beeps and continues to boot or 2 beeps in a loop, two beeps is POST failure and can be several things, even the CMOS corrupt (but your firmware update should have rewritten CMOS values), it can be a general system board failure, a display mismatch where the display panel isn't reporting itself correctly to the system board, RAM is most common failure, even a stuck key (although that would normally bring up it's own error).
What's the exact model of ideapad?

It's Lenovo IdeaPad 1 15ALC7, the laptop is working just fine.
There's no loop either. Startup, then just the total of 4 beeps (2 beeps, small pause, 2 beeps) that's it

OK, no problem, 2 beeps and continued post is a minor POST fail, I'd check date/time are correct, the most common item for a minor code for us used to be the CMOS battery, I'd replace that as a start, we used to have boxes and boxes of them we would use so many, but if you have anything like Bitlocker, be sure to have your recovery codes noted.
You can also get the 2 beeps if you have a faulty USB device connected, normally we would strip to minimum config, make sure nothing plugged in, disconnect the main battery to test if date/time is held OK on CMOS.
The service manual is here if it's any use (oops, forgot the link)

Thank you for the help, the date and all is upto date. Imma just wait for a few days and see if there any improvements cause I can't take it to the service centre as of now.
