Sony :: Vaio SR490 Power
Nov 11, 2009
So my brand new SR490 is already having some weird power issue. What happens is, the adapter stops powering the computer. This started happening randomly last week. I would be sitting there on the computer, and the screen would dim (I have it set to do this when it goes onto battery power).
I would move the adapter around, make sure it's plugged in right, but that didn't change anything. After a few minutes,
it would switch back to AC power by itself. It was worse last night, when the battery actually died because it wasn't getting a charge. The computer was just sitting on the desk and it kept switching between AC power and the battery .....

I am a college student looking to purchase the SR series VAIO notebook. On the Sony Style site they list two SR models the 490 and the 420. Both have the same exact configurations except that the 420 says that it has a much smaller projected battery life than the 490. Does anyone one if there is a hardware difference between these two notebooks to account for this difference? Or is this just a typo?

why the BIOS version R3220Y1 on the Sony support site is dated 10/13/2009. I downloaded the same version off the site several weeks ago so I am wondering why it is dated only 4 days ago.

I am upgrading my Sr490 to windows 7. I was wondering what software I have to download and what drivers. I am also looking for the one click check up and vaiocare stuff that came with the sr490 originally.
how loud people think their SR is.

I'm typing this on my other computer, but my Z has mysteriously encountered some power problems all of a sudden.
I can't turn it on. It just happened all of a sudden. No noise, no lights, no movement.
I did manage to turn it on by taking out the battery, unplugging it, and waiting 6-8 hours afterwards, it would turn on, and in the middle of booting up, it turns off. If I'm lucky, it'll make it all the way into windows and then shut off again.
I have to mention that I have opened up the laptop previously about a month ago, and cleaned the vents and fans off with compressed air, and applied AS5 to the CPU and GPU. Not sure if that's related, but that was a while ago.

I've been all over the internet, gathering whatever info I can find, but I'm stuck. It's a Vaio PCG-FRV26 (PCG-9J5L) that just shut down one day, had a very slight 'burn' smell & will not power on, no lights. Opening it up it was full of dust balls & the fans were filthy - cleaned it real nice with vacuum & compressed air. I replaced the power jack, had it tested & there definitely is power to the board, also had the AC adapter/charger tested & it's good. I also played with various combinations of RAM chips in & out, re-set button, on/off with adapter & battery in/out combinations, holding on button variations etc. Still no lights or power. I've opened it up 3 times now, everything looks new/intact/great.
I have a PDF manual for this series, but cannot find the CMOS battery in the laptop! I don't think the manual is that great, not enough info, detailed explode schematic is not enough, tricky to follow, says where the CMOS/RTC bat is but I can't find it. Is it under the motherboard? do I have to remove MB?
If laptop did overheat - can I re-set it?

Since VAIO Power Management doesn't work perfectly with my FW in XP, I am looking for an alternative. Is there any 3rd party Power Management that would work with my system?

I have a VAIO VGN SZ230P. It has always worked fine. Recently, it has begun to hibernate after about 5 minutes when plugged into its power supply. When on battery, it operates normally. I have tried two different power supplies, same problem. All sleep, hibernation and power setting are off, yet it still happens. All virus and malware scans come up clean.

I have a Vaio Z550N and although it was working perfectly until this point, now I am having the issue of the computer freezing up (completely non-responsive) when I re-attach it to the AC adapter after having had it on battery power.
It doesn't happen every time... but it is enough to be exceedingly irritating. The only major change I have made to my computer recently is upgrading the BIOS to the latest version from the Sony Support site.

I know of course that the current Sony utilities are not really meant for Windows 7.
However, does anyone have Windows 7 RC with the VAIO Power Management utility installed?
If so, do you also see the issue where the PM plan is not called 'VAIO Optimized' but rather something like 'SPMResMui.dll,-100'? If you do not see this, could you please tell me the version of VAIO Power Management you are using?

I have a 12'' sony vaio with a 16V power adapter. My battery is not good anymore, it was not even holding for 20Min, but my problem now is that the computer does not turn on without the battery at all. I have to leave it charging for hours, then it will go on, but in the middle of the windows loading process it shuts down and does not show any signs of life until you leave it charging for another hour.The voltage output out of the power supply shows 14.70 ~ 15.20 never gets to 16V. Now, comes the questions...
This particular laptop needs a good battery to " buffer" power and the AC adapter only charges the battery but does not have enough Amps to run the computer without the battery?
or
Do i have a Bad power adapter that is not even charging the battery properly?
or
Bad power supply and battery?

I recently sent my Sony Vaio FW in repair, the hinge was squeaky and on the verge of popping off.
They took it in and repaired it under warranty, but there is still a little play in the cylindrical shaped housing of the power socket.
Is this normal? do all vaios carry this vunerability?
I keep my vaio on my desk and avoid putting any stress on the housing of the power socket.. the power button housing on the other side of the machine feels rock solid.

my power brick making a clicking noise and the LED light sort of flickering in conjunction with the noise. Does anyone else have this issue? I'm not sure it's a problem, but I'm worried that it might be.

Yesterday a sony partner changed the mainboard in my z. Vista runs fine but the z didn't power off! When i shutdown the system it will reboot!
Hibernation and Standby also doesn't work - the screen went black, hdd is working and after a few seconds the desktop is back!
What can i do? I've tested some of the recovery points without success.
Same problem when starting in safe mode!
For information: when shut down in the bios everything is ok, also when booting from an ubuntu cd!
There must be a way to fix this - i hope without doing a system restore from the dvds....

I have a new Sony F Series with an 820QM CPU. I notice the performance drops to a very low level when the unit is not on AC power.
I have chosen the high performance power profile, and set the Min and Max processor states to 100% both when on AC power and on battery, this didn't help at all .....

Trying to get rid of these questionably useful programs -- but I don't see entries for them in add/remove programs in the control panel (or for any of the other useless VAIO software packages that come on OEM machines sans "fresh start")

Does anyone have a link to a website or PDF describing how to properly open and disassemble a VAIO VGN-SZ75GN?
I have a VAIO VGN-SZ75GN, bought about 8 months ago, and now I want to exchange the built-in hard-disc with a solid-state disc.
I need some guide with illustrations/pictures, how to reach the disc

I have just been given a VAIO PCG8A2M (GRX316MP) , i was told "it's broken but if you can fix it yo can have it" so having a quick look at it there's no sign of life on the display but the lights come on and i can here the HDD heads moving about.
Looking a little more i found that all the ram is missing , so now im not sure if its worth buying some ram to see if it works or not ? The lack of ram would prob explain the lack of display but i wonder if i should be getting POST beeps at least, which im not.
So my question is if a VAIO had no ram should (if all else was working) it be getting POST beeps ?

Just performed a successful XP downgrade on my Vaio Z520, but have noticed that on this copy of the Vaio Silver Desktop Theme/Appearance doesn't exist.
I had it on my SZ and loved it over the XP Blue. Is there a way to get it back? I still have the restore discs from the SZ.

I don't know whats the diference (besides the price), between VAIO TZ295N & VAIO TZ395N. Specs in all the websites I've checked say they have exactly the same components: Intel coreduo 1.33Ghz 2GB RAM DVD-RW and 64GB SSD Hardrive. I was wonder if the diference might be in the hard drive interface, with the TZ295N being PATA and TZ395N being SATA.

I'm wondering if the Blu-ray optical drive (Panasonic UJ-232A) of the (old) VAIO Z series will be able to fit into the (new) VAIO Z series? I would really appreciate it if anyone is able to answer my question.
The reason I'm asking is because I'm seriously thinking of selling my VAIO Z690 & just buying the base Sony VAIO Z (VPCZ112GX/S). I may just be able to afford that base model & the icing on the cake will definitely be the UJ-232A drive being able to fit into the (new) VAIO Z series & work.

Am planning to get a sony laptop for me. The design simply rocks I am getting mixed reviews about cw and E series. But i made up my mind to get one.
My budget is aroung 40000rupees. Thats around 800$. So suggest me a better one between these two for occasional moderate and less(mosltly) demanding games. I dont care whether its 14 or 15 inch.
Am looking at lower end versions of both the models.
Only difference is CW uses Nvidia Geforce 310 and the E series uses some Radeon 5000 series one. CW has 14 inch screen whereas E series has a 15.5 inch screen. In the models which i am looking at both have matte finish and both has WXGA:1366 x 768 VAIO Display.
which one should i go for. whether the screen quality will be on par to Inspiron one atleast? ( I dont need HD).

im planning on using the laptop for videos, photoshop and a bit of gaming, maybe even a bit more gaming :-)
The Vaio F Series only has 330M Nvidia Graphics Card with i7QM and up to 8GB of Ram and up to 256GB SSD.
The E Series has ATI 5650 (a less powerful version, reduced clock speed) combined with a i5 520M with up to 6Gb of Ram and up to 500GB of HDD ? Why can i not choose SSD ?

if I can use the AC Adapter of a Vaio TT on the Vaio Z. The standard AC Adapter that comes with the Vaio Z is of 19.5V and the one for the Vaio TT is of 16V, which I don't know if it's enough for the Vaio Z to function properly or if there could be any problem or damage. Both machines have batteries of 10,8V.
I have an undervolted Vaio Z by the way (last multiplier at 0.9875) so I don't know if this could help in any way for my Z to work ok with the TT AC Adapter.
