Laptop recos below 40k

I have a WFH job working 8 hours a day, 5 days a week unless i am asked to cover my co-worker's shift then a day's shift could run at 10-12 hours. Google/browser base tools with at least 10-15 tabs open. Slack for comms then youtube and netflix lang during work hours. I aslo used Capcut and Snapseed but for personal purposes lang naman. Non-gamer then ako. Priority ko sa laptop, ung may good battery life since I may travel while working. TYIA

Also, I already have 27" external monitor.
