Best place to get the memory upgraded (only the service) in my Ideapad S340 (torx screws on the rear) ?

It sounds like you know what you're doing, so why not just buy a torx bit/screwdriver set? If you don't want to wait for shipping from China or Amazon, here's one at Canadian Tire that's on sale for $14 that also has torx security screws:

Generally, once you get the cover off, it's easy to replace the RAM. It makes more sense to pay $14 and have the bits for future use than pay someone for such an easy job.

Just buy a torx screwdriver set.
This set is on sale for $12. https://www.canadiantire.ca/en/pdp/mast ... 3781p.html

Also, in a pinch, you can often loosen a torx with a flat head that fits into the torx edges.

Sounds like 2 gb is shared with the onboard video card. I'm surprised that it's using torx screws. If you swap out 1 ram chip your computer won't be using dual channel mode. I'm unsure how much slower it might be. Maybe it won't even be noticeable to you? I remember swapping out my memory to use dual channel. I didn't notice a difference for my everyday use (not gaming).

Thanks, I agree with you that it's simple after removing the cover, just recently upgraded memory in ThinkPad T480.

This IdeaPad torx doesn't seem easy. I indeed used driver (though bought cheap, off ebay) which had about 6 Torx variants, and with it only managed to unscrew 3 of 10.

I'll check the CT one. I'm just afraid that I'll spoil (strip) the screws and leave scratches around, if I ain't using the right-driver or doing it the 'right way', like pros.

There's a chance that you're using the wrong sized torx bit. Try the set from Canadian Tire. There are a lot of different sizes in it.

Probable. Between the two shared above, which one would you suggest if I may ask. Outside this specific use-case, my need is minimal. Is the 12$ set(Mastercraft Security Bit Set, 61-pc) usable by itself, I think I need to buy a driver separately? Thank you.

I would suggest the one from jm1 for $13.99. I have that set (I think it's this set). It has all just torx bits and all the sizes are there. The other set is a mix of everything.

I can't tell from the ebay listing, but since it's only six torx bits, then likely you'll encounter some torx screws that won't fit the bits, which is probably the problem you're having now. The $14 CdnTire set has every torx bit size you'll ever encounter. The other set has other bits (and much less selection of torx) that you can buy anywhere, even the dollar store.

I have an extensive set of torx screw drivers. If you're north of the GTA, I will be happy to help you open the cover

my windows 10 1909 shows 7.85 total memory out of 8gb with available 1.14gb and a bunch of other virtual memory numbers and page file size on my 8th gen i5 with onboard intel 620 gpu with shared

checked my other laptop on server 2016 and the 6th gen i5 has 7.89gb total memory out of 8gb installed so something is up with yours depending on what OS and hardware you are running

ok saw your specs and i have never had an amd or amd gpu so it does stuff differently but you can get feedback from others with amd and amd gpu's to see if the memory numbers sound right

Thank you for the kind gesture, fellow RFDer, appreciate it. I live in Albion/Etobicoke area and unfortunately don't have private transport.
Happy holidays to you

Merry Christmas. The world needs more of people like you.

Interestingly, Lenovo has this tiered guidance to what customer can do (or not do) at his/her end (I didn't know this before).

CRU - Customer Replaceable Unit. FRU - Field Replaceable Unit.

For a Thinkpad T480, memory-module comes under Optional-service CRU.
https://download.lenovo.com/pccbbs/mobi ... hmm_en.pdf

ThinkPad computers contain the following types of CRUs and FRU:
– Self-service CRUs: Refer to parts that can be installed or replaced easily by customer themselves or by trained service technicians at an additional cost.
– Optional-service CRUs: Refer to parts that can be installed or replaced by customers with a greater skill level. Trained service technicians can also provide service to install or replace the parts under the type of warranty designated for the customer’s machine.
– FRUs: Refer to parts that must be installed or replaced only by trained service technicians. If customers choose to replace the FRUs by themselves, the product warranty might be affected.

For this Ideapad S340 being discussed here, it's strictly NO under both self and optional-service CRU, for all parts including the unit's lower case.

If you scroll-down to P34 of IdeaPad manual, even the screw-types are unique: 9 of type M2.0 x 6.5 , and 1 of type M2.0 x 3.5. It's as if to make it totally difficult for a layman to disassemble (pry-open after unscrewing doesn't appear easy either by the look of it). I'll respect that and rather speed up the machine by removing bloatware and turning off background-apps.

Thank you for all your inputs and help

PS: One can get detailed pdf manuals for their device, by clicking on 'Hardware Manual' under their product, on Lenovo Product Registration page.

If the 9 means a T9 then my MasterCraft set has one. If the screw head has 6 points (like a star) then it probably is a torx screw. I don't know what else it could be.

There are other torx-like heads, but they're less common.

What the heck?? Why are there so many? And why is Lenovo being difficult?

Different costs, advantages and licencing deals.

Get one of the "X in 1" precision screwdriver sets off amazon or ebay, should have just about every kind of odd bit out there.

I needed a triwing bit for the lugs on my Oris Aquis, I got this set https://www.amazon.ca/Screwdriver-Preci ... B0793SM5T3 when it was $14, same thing comes under a bunch of other brands in different colored cases at different prices.

There's even a 110 pc. version for $22 https://www.amazon.ca/Precision-Screwdr ... B07V5N4X1T

The quality was better than I expected for a cheap set, though not perfect; the bits are great, but there are minor fit/finish issues like the flex and extension shafts not being perfectly straight etc.

Maybe Canada Computer? I've seen people just bring their laptop to the service counter for support.
