Sony :: Vaio Z Freezes Up When Returned To AC Power
Feb 1, 2009
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.
my Vaio Z is only a week old and I've started to notice random system freezes/stutters when I'm just writing a document, chatting on msn, browsing the web and even some light gaming (Warcraft 3). The freeze is only for a few secs, but during the freeze, my music would stop playing, my cursor would stop moving, my video would stop playing etc. etc. This happens more often when I'm playing warcraft where the entire game just freezes for several seconds (although not lagging in the game, drop box doesn't appear for other players),
I have a theory its the CPU downclocking or upclocking which may be the cause or an issue with the SSD?
My current sepcs are the following: i5-540 4gb RAM Windows 7 Pro-64 192gb SSD Premium Carbon
and everything else that comes standard with the Z.
If my laptop turns on, it either freezes, BSODs, or black screens (could be anywhere from the windows loading logo to doing some work on word, etc.)
And if it doesnt turn on, well it does; the hdd light goes on (for a second), same with the battery light (the battery light is fine though), but the screen is black; i can hear hdd activity though and if i throw a cd in there, it spins properly and whatnot, but it just doesnt do anything past the blank screen.
An external monitor doesnt work, and reformatting seemed to have helped abit, but then it just got worse 2 days ago; I can't get past the black screen after I turn it on.
I'm 99% sure its a hardware problem, and I'd be willing to replace whatever it is if I knew what it was, but I dont know if it's the hdd, or the ram, or the video card, etc.
I've also taken the laptop apart; so reseating the ram and hdd doesnt work.
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 have a sony vaio vgn-n130g the person i got this from said had no power so i took it apart to check the jack,everything looked ok i unpluged the jack wire from MB and plugged it back in.
then i plugged in power cord and it fired up.i turned it on and off a few times worked good so i put it back together...worked fine after i got it all together and fired it up it booted and then i moved the notebook and the battery wasnt in all the way .
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'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?
When my laptop is plugged into AC power, and I decide to move to another room and unplug it, the laptop suddenly freezes. All the programs do not respond and the only way to fix it is to reboot.
HP tech is trying to help my by telling me to test the battery life and resetting the bios, however this laptop is only 2 months old and I had the problem since the begining.
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 would like my computer to ask for passworkd every time the notebook wakes up from sleep but the option is gray out on my settings under vaio optimased setting. how would i be able to change this
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 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'm having an issue where my lappy completely freezes up when it is on battery power. It will boot off of battery fine, and I can click to the desktop, but then all icons become unclickable and all keys/input functions cease to work, and after about 30 seconds, the mouse won't move anymore. If it is on and then unplugged, it instantly freezes. I checked and I have the most up-to-date bios and drivers. I'm a bit perplexed as I've never run across an issue like this before.
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?
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.
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 .....
I've had my laptop for a little bit under 2 months, so these are the things I have noticed.
Issue number 1: When you plug in the power cord into the computer, the screen freezes on what it is currently on. I noticed this issue because occasionally when I plug in my power cord, and try to use the mousepad to select something, the mouse pointer is gone! I have to unplug-replug the power cable to get the mouse pointer to show again. It seems to have to do with the screen
Issue number 2: when I carry my E7440 around in my bad, or have it shut for long periods of time >3 hours (I just simply close the lid), the computer will SHUT DOWN. The thing will shut down completly, even though I simply closed the lid! At first I thought it was just going into hibernate, so I disabled hibernate in my power settings. But nope, even when the computer is asleep, it will occasionally shut it self down for no reason at all.
Just now, I closed the lid on my laptop, and put in in my bag, then walked to my office about 10 minutes away. When I sat down at my desk and opened my laptop, to my surprise, it had shut down by itself! All of my open windows, browsers, and applications were closed, and upon opening chrome and microsoft word, I was greeted by "your browser did not shut down correctly" and "microsoft word has recovered files". This points to the conclusion that it was not hibernates fault, but instead a issue with the laptop itself shutting down when it is put in sleep. This issue needs to be rectified immediately if it is a widespread issue.
Issue number three: When the computer comes back from hibernate or sleep, the computer is very very sluggish, even when plugged in. It is sluggish forever, OR until the power plan is set from whatever it is to "high performance". upon switching to the previous powerplan from high performance, the swiftness of the system is restored. This indicates to me that the system is throttling itself after it resumes from hibernation, why. This needs to be fixed; many people (myself included) just thought that the system itself was slow and underpowered, not realizing that it was just throttling itself when it emerged from sleep or hibernate.
What if you sent it back because it was defective? Will they strip the working parts and use it in their next new laptop build, or will it go into their spare parts collection?
I recently called Dell to have my laptop repaired and they told me a technician was going to call me which he did, but my schedule was too busy so we rescheduled for last Friday but he never showed.
I called him Friday afternoon and he said he was going to come on Saturday and again he never showed.
I decided not to harass him and call him again and now it's Monday afternoon and there is no sign of him
I recently purchased a refurbished M4400 and have had a sizable amount of problems.
Dell is in the process of trying to rectify my problems. I am considering returning this notebook for a refund.
Has anyone had experience asking for a refund? If so, did Dell try to offer any incentives (a money discount/credit, etc.) to try convince you to keep the notebook?
I've discussed this machine in other threads, but it wasn't until now that I found out that a restocking fee was charged.
The machine in question had problems with a wavy keyboard and an eject button that would stay lit, then go off and eject a disc at random. This happened multiple times. I also had a problem at boot up, where the machine made a ringing noise for over one minute, then booted up. Given these problems, I called Dell to return the machine after having it for two days.
The machine was a "Previously Ordered New" Inspiron 1537 from the outlet. I think it's not too much to ask that it be free of defects out of the box. If there are multiple problems, then one should be able to return it within 21 days for a full refund.
If you find yourself in a similar situation, my advice would be to make sure someone in Tech Support logs in the system the problems you are having. I didn't realize that this was necessary .....
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")
