CPU - get the i5 14th-gen. If budget constrain, i5 12th-gen pun good CPU. Try not get into seller trap, which they might sell AMD Ryzon or something, as AMD is battery hunger, and AMD have bad history of over-heating. If you are gamer, yes, go for AMD.
RAM - if possible, get 16GB RAM. If budget issue, get 8GB minimum. Do not get below 8GB. Chrome nowdays a little mafia-eating-memory. If possible, get 16GB - comfortable for long run usage, example 5 to 10 Chrome tabs.
HDD - get with SSD drive (which range around 256GB to 512GB. Do not get normal spinning 1TB hard drive (seller might hard-sell you, saying 1TB is much more spacious, but, it is slow) - realistically, in normal work, 256GB or 512GB is good enough (unless you need for video editing or Photoshopping)
Screen size - if need big screen, get 15”. But, it is less portable compared to 14” - In my personal case, I prefer to be highly portable, so I opted for 13”, can do work anywhere.
Kalau boleh, if budget is good, boost up the RAM, 24GB ke.
