Got this one 5 days ago, used off eBay. It has everything, 16GB RAM, WQHD display, Samsung 1TB SSD. It's used as a desktop replacement with a Lenovo Ultra docking station. I am a ThinkPad specialist, since I have 4 now & 2 which have gone to new owners. The weak point in all is the USB-C charging connector, they are easily broken & not user or shop replaceable. There are 3 reasons for this. 1) They are unique to Lenovo, 2) the solder pads are under the connector 3) there are five tiny signal filters (inductors) that can fly off the board from the hot air gun. If the motherboard is replaced, you need the proprietary software to reprogram the BIOS. The combo connector next to it can also be used for charging. As you showed, the bottom cover is difficult to remove, the X1 Carbon of the same generation comes off a lot easier.
BTW, Lenovo has hardware maintenance manuals online for all ThinkPads. They show with pictures & text how to disassemble everything.
Lenovo doesn't design the usb c very well
Pressing the power button for 15 seconds is amazing tips, never knew that before, thanks Binh.
No problem :)
@@ItsBinhRepaired I had the same problem and after pushing that battery reset for 15 seconds my T490 is back to life! Thank you thank you thank you!
Battery reset with needle workaround helped me. Thank you so much
Awesome
@@ItsBinhRepaired I was so worried since it’s my work laptop and that fix really helped me 👍
0:12 that CMOS battery reset hole tip saved my work laptop, THANK YOU SO MUCH!!!
P.S. I had this laptop for more than a year and I mostly keep it connected to docking station.
Awesome, glad it helped! Please help me by liking, subscribing, and sharing my channel with others so they can fix their devices as well. I also have other content if that's not interesting to them. Thanks!
nice video, thanks
the keyboard's 2 screws are under the trackpoint left and right click buttons.
the buttons come off by lifting them from the touchpad side w/ a prying tool, slide the keyboard towards the screen then lift it from the touchpad side.
Nice
Thanks bro for the teardown tutorial.. fairly detailed information
Glad it was helpful. If you haven't already, please like and subscribe so others can find my videos. Thanks!
The CMOS battery reset did the trick. All of a sudden my laptop won't charge. I reset my laptop from the back side as explained in this video and voilaaa. It started charging.

Hi Binh, thanks for sharing this useful video. It helped to disassemble and fix my laptop not turning on. There was corrosion on a component (not sure how it happened, may be due to moisture or water drop) and I reset the battery bios as you suggested, which might resolved the issue.

Thank you for the tutorial. I want to ask, can we disable battery supply via BIOS?
So we don't need to remove the battery socket.
Not sure. I don't trust software disable though
@@ItsBinhRepaired Ok, thanks
@@ItsBinhRepaired For the RAM update scheme, can it be 16+32? or is the maximum only 16+16?
Usually there is no max.
really helpfull thanks

I have a T590, and it got the third mainboard under warranty, and my USB-C is still not working. So painful... I need to find a better laptop.
Strange. Did you tell them that was the issue?
Hello! I hope to find a solution or at least some advice. I have a Thinkpad T490, and recently encountered the following issue. The laptop doesn't start, but when I press the power button, the LEDs light up for about two seconds, the fan starts for two seconds, and then it stops. After another 4-5 seconds, the fan and LED start by themselves, and I hear a single beep. It has 8GB of RAM soldered to the motherboard, and I've tried almost everything. I've tested it with an additional RAM stick in the slot, a different SSD, and with and without the battery. I've tried pretty much everything I found on forums.
Sounds like a motherboard issue. :(
I have bought this model almost 1 year ago and I love it! But after I opened it up to add ram I noticed that front side (near the trackpad) of the bottom panel does not tighten well with clips. So now the front side of the case (palm rest ) become squeaky and there is very very little gap between bottom panel and top panel. I opened it up again to inspect if something was wrong but could not find anything unusual, clips are intact, they are not broken or something. it just does not snap in titer. Do you experienced same issue ?
Not sure. possibly not lined up right if you're sure the clips are fine.
I have bought this model yesterday.. T490
I was wondering, can i add sata 2.5"?
No room
Hello sir... Am having the same problem, tell me do you think it can be a motherboard or a static power build up? the light blinks 3 time when i plug the charger .. yet it's charging the battery... am thinking of dissemble everything, do u think it can be my motherboard? or just a matter of static power?
Not sure. It can be anything. Try RAM or motherboard.
Hi, I’m about to get a T490 with windows 11 installed. But the laptop itself has two issues which are the speaker and audio jack are not working. Is there anyway these problems could be fixed?
@@cheesefries6616 check the device manager if your sound driver is installed.
@@ItsBinhRepaired I just checked device manager and found out that the Intel(R) SST is missing. Do you think re attaching the speakers or replacing the speakers on board would fix this problem?
@@cheesefries6616 no, the audio jack would still work.
@@ItsBinhRepaired I don’t know but no matter I plugged in my headphones or not, the speaker remains disabled or not detect anything.
@@ItsBinhRepaired Also the Audio inputs and outputs section from the device manager is missing
hi. can you help me how to insert simcard in this laptop? i don't know how to do that. tnx
You need a pin to eject the tray.
Hi my laptop was not responding when pressing power on button or connecting charging cord. Saw your video tried to reset CMOS it worked for second time. I connect power cord and the laptop booted up but after I typed my login password it again turned of now it is not responding. Again tried to reset but it is not doing anything any Idea what the issue is. Laptop is 4 years old lenovo t490
Very strange. Not sure other than maybe the cpu fan wasn't working and it overheated.
@@ItsBinhRepaired Man so nice of you to respond so quick. Anyways I'll tak it to shop and let the guy check. Thanks
@@austinsamuel4933 good luck
is it ok not to wear an anti-static wrist strap?
As long as you ground yourself and make sure static isn't being built up.
i need solve for Self-Healing BIOS recovery progressing (lanovo gaming 3)
Not sure
hi i forgot my bios password how can i take it out?
Not sure
does this model come with sim card slot ?
Not sure if I didn't mention it in the video.
Look first 2 minutes. He showed but didn't know Sim card slot
What size of m.2 ssd should i get? 2242
2260
2280
Please answer ❤
2280
@@ItsBinhRepaired thanks
Yup
over 8min into this and nothing about the Harddrive or Ram!
Maybe watch the entire video.
If you don't see the SSD the moment the cover is removed, then you need all the information this video has to offer.
@@ItsBinhRepaired That's not the point smart guy! the title say's Ram and HHD upgrade but it took over 8min to get to it! That's the point! Just take the constructive criticism and move on!!
@@bowe1978 it also says disassembly smart one. You think I can put every single component I touch in the title? There are character limitations. Battery, cmos bios rtc battery, wireless card, etc. How long do you want the title to be? It's in the title because it is in the video and it's what most people will search for.
@@bowe1978 if you don't know what a RAM slot or an SSD looks like, then you need to watch the entire video. There is thousands of dollars of useful information in this video and you just want to know what an SSD and stick of RAM looks like? Why don't you just Google SSD and RAM? Bit of useful criticism for you.
