Sony Vaio Notebook SVF152C29M

Please help me to identify my Sony Vaio notebook and find the user manual and the drivers for it.

On the bottom of the notebook is written MODEL SVF152C29M.
On the Sony website support I cannot find this model and I do not understand why.
It has a Intel i5-3337U processor with 4GB RAM, Win10 64bit Home.

Probably the drivers and user manual may match from another model, but which one? And why is not this one listed?

That similar model SVF1521C6E I have seen it too, but was not sure is good for my model.
I refer about drivers and user manual.
So, there is no where to be found direct info about it?

It was a eSony page with auto detect model number in the past.
Why I cannot find that either?

I spent some time on the Sony site and the computer was out of support December 2017 (nearly a year ago)
Gerwin Jansen, EE MVETopic Advisor Commented:
Did some searching as well, apparently it's the same model as this one:
Owen RubinConsultantCommented:
Well, you are not the only one to have one. Here is one on eBay:

Here is a site that lists the computer, but they claim an i3:

Here is another site:

It appears that this was a European version of a Sony Laptop, as all the links I find are in Europe. Your Sony Vaio SVF152C29M is a SVF1521E6E as far as I can tell. This page, in French, is as close as I can find:

This is a fairly old laptop. Maybe knowing what you want to do would help here?
viki2000Author Commented:
The notebook was sold and bought in Germany, so it is an EU notebook.
Now we have 2 expert opinions: one says is SVF1521E6E and the other SVF1521C5E.
Which one to choose?
But where do you see written the reference/connection between on of these 2 models and SVF152C29M?

In mean time I wrote an email to Sony support directly, let's see what do the say.
Gerwin Jansen, EE MVETopic Advisor Commented:
The site has the SVF1521C5E reference (and some more):

Hmm, wonder what "Wo finde ich den Modellnamen auf meinem Gerät?" means?
it means where do i find the model name of my laptop

@Gerwin Jansen, EE MVE
If I go on that link, that I already tried several times before I asked the question, I see a lot of models (just click "+ Mehr anzeigen") and all have written "Diese Produkt ist auch bekannt als SVF152C29M".
So, there is more confusion than help and that's not due to German language, weil ich spreche Deutsch.

You got me here.
I have gone trough that link several times before, I knew it, I somehow ignore it temporally and then I forgot about that check.
I did not want to remove the battery. I just bought that laptop 2nd hand cheap and was a headache because had Win10 in Arabic language and with ugly partitions. Now the language is solved, the partition too and finally I opened up the battery. It is good that you remember me to do it. My mind is sometimes behind my head :) , especially after non-sleeping nights due to diapers change for the little one or an ugly work day...
Anyway, I have it now and is SVF1521B4E.
Now I have access to all the drivers from Sony support, only the user manual seems that is available only in Hungarian language, which I do no speak. It is enough 4 languages for me...
So, if by chance you find the user manual in English, German, French or Romanian, then I would be happy to have it.

That Hungarian document is not a user manual, I can't read it either but It has no line drawings, list of BIOS settings or part numbers all which would be in a proper user guide.
viki2000Author Commented:
I opened the user manual in Hungarian language and I have visually inspected it. It does not seem interesting for me.
In fact I need to know 2 things:
1) About RAM memory.
I noticed there are 2 physically slots for RAM memory and I would like to know what is the max.  allowed RAM memory capacity to be installed.
How can I find that?
I hoped is specified somewhere in the user manual or some kind of specs.
Online I noticed some specs say that I can install max. 2x 4Gb for some models, I guess designed with i3 processor, but I have i5 and some say is allowed up to 16GB, meaning 2x 8GB.
I have now only one RAM chip installed in one slot. It is 4GB and I would like to install another one of 8GB, to have 12GB RAM.
Can I do that for this model of Sony Vaio? Where can we find the specs?
Here are the specs of the actual 1x 4GB RAM:

2) About the HDD.
I would like to replace the existing HDD TOSHIBA MQ01ABD050 500GB 5400RPM SATA II with an SSD 2.5” 512GB.
The question is: how do I know the max bus speed used by notebook?
Can I use SATA III and have the speed of SATA III?
Or is it everything reduced at SATA II?
Or, do I see SATA II only because the TOSHIBA MQ01ABD050 is SATA II?
I do not want to buy a SSD, let’s say as Samsung Pro 860 512GB, which costs enough money, and then to not be able to use its speed.
Here are some specs that I found by scanning the PC with dedicated inspection software:

It appears to take 16GB,

SATA III will clock itself down to SATA II so any SSD will do so long as it fits.
viki2000Author Commented:
Yes, I have seen that link before when I tried to buy some RAM, but I was not sure that if it is true or they only try to sell their RAM.
Last weened I bought next RAM chip Crucial CT102464BF160B 8 GB:

I will see during next weekend if it works.

"SATA III will clock itself down to SATA II so any SSD will do so long as it fits" - here I really have a probelm of understading.
I am aware that if SSD is SATA III and the internal bus is SATA II, then applies what you said.
My problem/question is: is the internal bus SATA II or SATA III? How to know that?
I can buy  a SSD SATA III cheap or expeninsive and I do not what to spent the money on one SSD expensive if it is clocked down to SATA II because the internal bus of the notebook is only SATA II.
Do you understand my problem now?
viki2000Author Commented:
It seems there is a very high chance that an SSD SATA III will work at full speed.
I have used some hardware info software as seen in screenshots below and more.

It says that SATA Port 0 and 1 can go at 6GB/s and another that bandwidth is 6GB/s corresponding to SATAT III.
I checked the South Bridge controller, which is Intel panther point HM7 and its specs says 6 SATA Ports from which 2 are 6GB/s:
There is also written on some internet pages that after 2009-2010, most of the SATA Host controllers are SATA III and not II any more.
Another software as Sisoft Sandra says for instance that I can install 32GB RAM…, but being only 2 slots available, the price for 16GB SODIMM 204 pins costs too much, better stay with 2x8GB=16GB. In fact, for what I need, 12GB will be enough.
So, now I know next:
1) Notebook model name is SVF1521B4E
2) Can work with at least 16GB RAM DDR3-1600, PC3L-12800, SODIMM, 204-Pin. 1.35V
3) Very high chance to work with SSD SATA III 6GB/s.
viki2000Author Commented:
Here is my last concern: which SSD should I buy?
I need a 500GB/512GB 2.5” type SATA III 6GB/s.
I have found next good comparison about Samsung SSD:
Evo is around 90-100€, while Pro is 145-160€.
Makes any sense to pay for Pro having in mind the notebook above?
Do I really need the 860 series or is good enough 850 series?
What about a 2nd hand 850 Pro with only 70€? Is not that a good offer?
Or why not an Intenso new MLC with 75€?

How would you choose and why?
i find the speed difference not worth the cost
they say :   In everyday life, however, most files are rarely several GB in size, so the TurboWrite cache can always intercept everything.
just my thought
viki2000Author Commented:
Yes, I guess you are right, at least I tend to believe the same, but I wanted the opinions from more experts.
I looked at the next website to compare some SSD:
If I buy a used one as for instance Samsung 850 Pro with 70€:
I see 29.5 TB Total Bytes Written.
Then I read here:
and then here:
and I see the lifetime is 10 years or 300 TBW, which means 29.5 TBW is only 10% of the lifetime used and is still good for next 270 TBW or 9 years; then 70€sounds as a good deal for 512GB.

P.S. I do not remember from where I downloaded it during the last days, but here is the user guide for this PC, in case someone needs it in future.
i have bought new Kingston 480 GB SSD for 70 Euro

i don't use them extensively, so i probably never will reach the projected EOL
The question was "Please help me to identify my Sony Vaio notebook ...", it seems to be diverging. IMHO you should close it and open another.
viki2000Author Commented:
You are right, I am sorry for that. I will close it now.
None of the participants here seem to had in the past a Sony Vaio with Assist button.
I did not have and did not know either that if the Notebook is off and if I press that button instead of the power button, the the PC starts with a special menu for Windows recovery, BIOS setup, contact for support...and at the bottom of the screen is the model of the computer, the one hidden under the battery label.
I thought that Asist is more as ThinkVantage Button from Lenovo, but seems a bit more.
For some reasons the Win10 is blocked now, does not want to start and when I when trough the repair procedure I had a bad surprise to see everything again only in Arabic language - the installation  language of the Win10, meaning the additional English language is seen only as long as Win10 is healthy - bad. I will reinstall everything from scratch with Win 8.1

Assist Button
Model No in special screen

Thank you for all your suggestions.
tx for bringing the "assist button" to my attention - i never knew such a beast existed
viki2000Author Commented:
In mean time the RAM chip module Crucial CT102464BF160B 8GB arrived and works without problems.
I have now 12GB, enough for this old notebook.
Owen RubinConsultantCommented:
I have had several Vaio systems but never had an assist button. That is new to me as well.  Good luck with your restore,,

Just a follow up for future readers.
I have bought and installed one SSD Samsung 860 EVO 500GB.
