Lenovo ThinkPad T490 comes with an Intel Whiskey Lake processor. Users can choose an Intel UHD 620 or NVIDIA GeForce MX250 discrete graphics card according to their needs. It supports up to 32GB (16GB expandable +16GB onboard) memory and 1TB PCIe NVMe SSD.
ThinkPad T490 features a ThinkShutter, which can physically close the camera. The Infrared camera and fingerprint recognition module are also optional.
The laptop supports up to 14-inch WQHDIPS screen and covers 100% Adobe RGB wide color gamut, with IPS wide viewing angle technology, even in bright light can see the content. The frame on both sides of the screen has a thickness of 8.6mm.
Lenovo ThinkPad T490 weighs 1.49 kg and is 18.9mm thick. It supports fast charging technology, which can recharge 80% of the battery in one hour, and has a battery life of up to 13.6 hours.
I have seen many users have gotten and upgraded the memory and SSD for their T490, here to share with you the experience of upgrading memory and SSD.
The first thing to do is unscrew the screws that secure the bottom cover and then insert a thin plastic tool under the bottom cover. The bottom cover has many hidden latches fastening it to the palm rest. You need to move the thin plastic tool along the side and unfasten all latches.
With the bottom cover removed, you can access the battery, SSD, CMOS battery, RAM slot, cooling fan, heatsink, and motherboard.
ThinkPad T490 comes with an 11.52V, 4345mAh, 50Wh Li-ion battery. The part number is L18M3P73, 02DL008. The most significant difference between the ThinkPad T490 and the ThinkPad T480 is that the T490 cancels the external battery and retains the built-in battery.
The Lenovo ThinkPad T490 has 8GB onboard memory and a free RAM slot. This slot supports up to 16GB DDR4 2400 MHz memory.
The laptop has a Samsung 256GB PM981A PCIe NVMe M.2 SSD. Of course, you can replace it with a bigger-capacity SSD. It supports up to 1TB PCIe NVMe M.2 SSD.
Here’s the WWAN 2242 M.2 slot of the T490. I saw that someone installed a PCIe SSD in this slot, but the system does not recognize it. This is very regrettable.
Of course, this can be solved by updating the BIOS. I hope Lenovo will update the BIOS to make the ThinkPad T490 support 2242 SSD.
