Lenovo T420 screen replacement

Posted 19th Apr
Hi. How easy is it to upgrade a Lenovo T420 screen & any suggestions please? Just bought one & the 14.1” 1366 x 768 screen isn’t overly good. Around how much would it cost?
Thanks all.

Ok. Bought laptop as cheap & easily upgradeable so I’ve read though I haven’t done anything like this before. But screen seems bit blurry when compared to a newer Asus laptop I have with a broken keyboard & a pixel damaged screen.

Any time there's a youtube tutorial to follow then everything becomes a lot easier. To replace your screen is very easy.

Bought with a 1 year warranty from newandusedlaptops4u
Hope by doing this it doesn’t invalidate the warranty?
You bought a used laptop and you want to replace the screen (£36.76). Are you sure you don't want to return the laptop instead. It's 2000 now, I probably would've went for a 5th gen laptop, and not a 2nd gen.

I thought it was a good deal & easily upgradeable.
Thinkpad T420 i5 2.50Ghz 4GB Ram 128GB SSD. £139.99. Windows 10.

Has been just over 30 days since purchased so might not take it back.

With a better screen it seems useable. I didn’t know what the screen clarity was like when I ordered the item.

This recently got sold out click, it's a 6th Gen i5 8GB RAM 256GB SSD. In comparison your laptop isn't a good deal. £13 more gets FHD screen as well.

Ok fair point maybe I should send it back then 30 days is today actually. Would need to pay return postage.

I did briefly look at that seller but the warranty is only 90 days so wasn’t sure about them as it is effectively a refurbished product.

Seems to be more wear/possible damage on that one then one received by their description too.

All I'm saying is you just bought a used laptop and you're thinking about replacing the screen, which will cost you £36 on top....Doesn't make sense. Only makes sense if you bought that laptop dirt cheap., but you didn't.

Ok. That’s what happens I guess when buying my 1st refurb computer. Maybe I should just send it back & cut my losses (return postage). The screens just not as clear as I thought it would be that’s all. Maybe I was expecting too much as it is an older computer.

Return postage is free is you paid by Paypal click.

Just looked at it again & it’s ok I guess. Think it’s because the screen is ever so slightly smaller than the one I have been using which makes the icon descriptions smaller. It’s ok. Bought it as was a cheaper alternative than a brand new laptop & tbh its better being able to see the whole screen & not having to use a USB keyboard.

No paid by credit card. So I would be covered if anything went wrong with it. Sellers return period says 30 days.

Starting to wish I hadn’t bothered now.
A screen replacement may not necessarily fix the problem.
Further diagnosis is required before concluding what the problem is. A number of other things need to be ruled out. Is it bright before the Windows OS kicks in? Is the BIOS screen bright?
I have replaced an inverter before on an older Lenovo but your T420 does not have an inverter.
take a look at these 2 links - but there are many others by searching net

forums.lenovo.com/t5/…987


forums.lenovo.com/t5/…700

Would an attached external monitor be any good for you?

I agree though - throwing good money after bad is not a good idea. In my view though an old T420 is a good machine and your spec is v.good. But yes you paid too much.
I would be very tempted to try a live linux usb on it - just to see how it performed and whether it could tweak the display to something acceptable.

Thanks.
I think I’ll send it back & look for a better deal elsewhere. I think the screen is likely ok just not as useable/readable (for my ‘getting older’ eyes) as I was expecting it to be. Like I said screen is v.slightly smaller than I have been used to.

Why is this one below such a good deal? I can’t see straight away myself. Better specs yes but also more expensive than I paid.

Because for sub £300 you're getting a new laptop with 8GB, 256GB SSD, FHD (TN panel though). That CPU is decent click, it's twice more powerful than the i5-2520M in your laptop, it's equivalent to an 8th gen i5. You can even do light gaming with the iGPU click.

Ok thanks. Have decided to return it & make a careful ‘’informed’ choice what to buy instead.
