Btw, may i know which model is it?

Maybe u can speak to the agent that help you during the purchase (i assume u buying from lenovo official website).

Just to confirm, since u say premium care, meaning they should come to your location right instead of u sending it to them?

But agree its unacceptable to have motherboard faulty in such a short time.

Bro, I'm using a Lenovo Thinkpad. The laptop is fine.  I just had an issue with the Wi-Fi which was constantly dropping.  I did a search on the internet and found that everyone using the 8822 chip set from Realtek had this issue.  Their solution was to get it changed to an Intel Wi-Fi card.  I called Lenovo and since I had on site support bundled in my purchase,  the technical support guy came to my house and swapped the Realtek with an Intel card and my Wi-Fi problem vanished.  The ThinkPad is absolutely fine now and it's a great laptop. I was happy with the service too.

Let me share another story.  Someone I knew had an Asus notebook.  This happened years ago. I can't recall exactly the nature of the issue but it was a suspected problem with the motherboard.  Brought it to their service centre in lowyat. They fixed it but the problem happened again.  I took this to the consumer tribunal and requested for a refund as the notebook was still causing issues even after a few  visits to the service center. I pain stakingly prepared all the evidence I had but at the end the judge simply decided to just extend the warranty and told Asus to get it repaired again.  My experience with the tribunal isn't that great.  I had another case with the tribunal for another product and that didn't turn out well either.  Consumer rights in Malaysia isn't like that of Western countries. The judges here think they are God and have inflated ego. Some are moody,  grumpy and rude.

Bottom line is,  I would perhaps suggest you to rather than immediately seeking for a 1 to 1 exchange,  first send it to Lenovo. Get the motherbosrd changed. After all it's still under warranty. Make full use of the warranty.  If they have replaced the parts and still if the problem persist than you may escalate this issue further to their manager and then try your luck at the tribunal. My experience with Lenovo was good though.  It helps if you have on site support but in this case I believe you don't. It saves you the time bringing it to their service centre each time a problem happens.  Use the the warranty and claim the parts. It's only after repeated  claims and the issue doesn't get solved you can opt for something drastic.  Usually these companies will not immediately entertain xchanges, at least in boleh land Just claim warranty first.

My experience with Lenovo..

I just purchased Lenovo Ideapad in March 2020 and within few days, it can't turn on. Brought to SC and they determine is motherboard problem and request for one to one exchange through HQ and then MCO got implemented..

When EMCO, they called me back and approved the one to one exchange

Overall took 2 months because of MCO and the new laptop is working fine

but a mother board fault is common problem being that most component are on it - i don’t get how it is disrespectful when Lenovo is replacing the faulty part as in the warranty agreement you agreed to when purchasing the unit. the warranty starts on the day of purchase not on when you think it should.

common problem also wrong not common but treat like common also wrong?

i had a similar experience with a tv it had a vertical line on the screen just over a month - took panasonic 2 week to replace the panel using the tv now into it 6th year.  didn’t whine not once i swear. 3k so what? if you buy 4k the company needs to prepare replacement units for you ka of your keyboard fail? 5k need to give you 2 units each time it fails ?

I kena with HP...., kena graphic glitch, auto reboot and blue screen after longer hours use and multitasking. Contact online support thru whataspp die-die said it a software issue.. need to update BIOS laa....,  check software update, local recovery, until they ask a cloud software recovery, lost my patient already... send to drop off center, lagi cilakak,, 2week there, they just do software recovery again... not even a day after collect, same thing happen again,  escalate to customer service at HQ with phone.. now waiting for on site service to come + waiting parts.....1 month plus old already the laptop.. collecting dust.....it's suck man... spend money for something you can't use at all and lousy after sale services...
