Even after installing current drivers and updating everything possible even doing as much as updating the bios. Nothing, it’s just not worth it spend a hundred or so more and get something better. Also the speakers are completely silent at 100% unless you go into myASUS and fidget with the settings and turning on 3 different things only then does it sound a little better.

$249 is Ridiculously Inexpensive
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Initially, I was skeptical about purchasing a $249 laptop, recalling the disappointing performance of similar budget models in the past. However, after researching the Intel Core-i3-1215U processor, I was convinced of its value and ended up buying two. These laptops offer excellent value for money, with impressive specifications for the price. One standout feature is the ease with which you can upgrade the machine: simply remove the bottom panel to add an extra 8GB of RAM for just $15, boosting the total to 16GB in a dual channel configuration. Additionally, it includes modern features such as USB-A and USB-C 3.2 ports, WiFi 6, and a PCIe Gen 4 M.2 slot—also easily accessible. The only slight drawbacks are the absence of a backlit keyboard and the use of a VA display, but these are minor concerns in an otherwise excellent budget-friendly laptop.

Asus Vivo book X1404ZA-I38128 Ok for the price
Posted .This reviewer received promo considerations or sweepstakes entry for writing a review.Model: X1404ZA-I38128 Bought as open box, excellent condition. Smelled a bit weird. No idea why. Otherwise seems like new. Only 33 hours on the HD when tested. Had an older laptop fall apart, emergently bought a non-OLED 14" Asus Zenbook. Motherboard likely died just out of warranty and cc company refused to lift a finger despite cc free extended warranty. LOL. Bought this in place of buying MB, fan, etc., to replace components on ZenBook. Don't expect too much from the Vivobook. They cut many corners to keep price very low, on sale for $230 new. Screen is quite usable, but poor angles etc. vs most laptops. Compared to other laptops, display panel is not that dim, despite reviews noting this. So about equally bright (or dim) to some other non-OLED screens I have compared it too. Eizo screen test shows very poor motion lag. So not for gaming or video work - I think much more expensive OLED screens would be far better. Keyboard is noisy and not backlit - so get a USB light for about $10-. Plastic body - but seems to be of reasonable quality. Only 1 USB C port (unsure of speed) and cannot be used to charge battery. So separate charger is required and included in box. 128GB NVME drive is pathetically small and very slow on ATTO and CD Mark tests. Comes with 8GB RAM. Others report RAM can be upgraded by buying an 8 (or 16) GB SO DIMM and you can replace the NVME drive at the same time. Being able to upgrade the memory is a big plus as unfortunately many new laptops come with non-upgradable soldered memory. Years ago, RAM and hard drives were easy and fast upgrades and only a few screws had to be dealt with (10 screws on the back of the vivobook). There is a (service) manual you can download to show how to do these upgrades from an Asus website. I do not know if the MB can handle PCIe4 NVME speeds. But even a PCIe3 at full speed would be much faster. Easy to get rid of Windows 11 S lockdown. Just remember that many apps will not load until you do this. Denbian Linux booting off a fast thumb (500GB Patriot Rage, 512GB PNY Pro Elite V2 or similar) drive worked well. There is a major wireless issue with the vivobook Wi-Fi card. Cannot find a Linux driver for the included card. I did not open the back to replace the Wi-Fi card with a $20-40 card. However, using a Dell laptop dock, I connected Linux via ethernet to the dock and USB C from dock to vivobook (no ethernet port on vivobook). Easier solution - used the $10- 802.11n USB A mini Wi-Fi thumb drive like device from my old desktop computer. Same for slightly larger USB A BT device - ZEXMTE. So, for Wi-Fi and BT you will lose USB port(s). Could also buy a 4:1 USB port extender, etc., but I did not test using these on the vivobook for the USB Linux drive, USB Wi-Fi or USB BT sticks. The highlight is the chip: i3-1215U. Benchmarks are fast for such a low-cost laptop. Compares well to the ZenBook chip. Benchmarks are about 3 x faster than my older i3-8130U 2018 laptop. For most office and many personal tasks, not sure that this makes a big difference for day-to-day use. For even moderate level gaming, video work or other CPU / GPU intensive tasks these less expensive laptops are not what you want. Have not had vivobook long enough to say much else. In the end not sure if it would have been better to get the MB and fan parts for the ZenBook repair at a similar price, but with no guarantee of success.
