VAIO VPC-Z11 Dont Power Up..

Hi a few minutes ago when i was copying a file from my 3.5 external drive, just a few seconds to finish the copying i plugged out the power cord because i had to go out. the machine shut down and never came back. i tried to plug out the battery and wait, or just power it up on power cord but it didnt work i dont see any reason to some part of machine is burned or something else my adapter is also fine.. did someone had this problem before or anybody have an opinion?

Sorry if I made mistakes when I write English is not my mother language & thanx to anyone who tries to help.

 

I am sorry to hear about your problem. I too have a VPC-Z11 and would be quite upset if that happened to me. Out of curiousity, do you see the charge light illuminate when you plug in the AC adapter to your Z with the battery connected?

 

thank you for the reply.

No light illuminate btw. first i tought I'm out of battery but there is no sign of charge or any thing when I press the power button. I'm very upset right now it was just working fine. If something happened to the circuitboard just because I plugged out the power cable I'm never gonna buy another vaio i think..

 

Stuff breaks. Did you try pulling the battery for a while?

 

I second this. My Samsung LED LCD just broke. My HTC Incredible just broke. My car broke down. My furnace just went out...all in the matter of a week. I buy warranties on EVERYTHING now, with extended ones.

Try pulling battery, yes... but in meantime, when did you purchase your Z and from where? You under warranty still?

Also, can you clarify what happened? Did you physically see the Z shutdown before file transfer was complete or did you walk away and come back? If you saw the Z shutdown, were there any errors or blue screen? Or did it just shutdown normally?

 

Sadly my unit is not under warranty because it was bought from another country. So like i sad there wasnt a proper shut down. I took the power cord out of the laptop and not in a second instantly power went off. So i was looking at the screen(copying process) while I'm taking the cord out so there was no shutting down or warning or blue screen or any screen. my battery was full and it went off like its battery percent was %0. but no charge or led signs when i put the power cord back on with or without battery.

 

Someone will have to correct me, but don't you have to hold the power button in while AC unplugged and battery pulled

 

Why would I do that. I tried to say I tried all combinations :/

AC plugged with battery on
AC plugged without battery off
AC unplugged with battery on

Still no sign of life. I pulled out the battery and waiting for a few hours to pass maybe it will take effect.

If power went back with no AC or Battery attached it would be a miracle I would love that =D

 

No, with many laptops, holding the power button for a minute with no AC or battery is supposed to reset CMOS.

 

didnt know that ill try immediately

 

It didnt work :/ nothing happened. When I went back home I'll diassembly the laptop and look for a burnt hardware on the mainboard :/

 

You might try also pulling the CMOS battery for a few minutes while you have it disassembled.

 

I couldnt find any detailed shots of the mainboard. Where exactly is the battery located on the mainboard?

 

It isnt on the mainboard, it plugs into the front left of the mainboard via a 2 pin cable.

You should also check your USB ports and make sure the pins aren't shorted or bent as these being grounded would cause the machine to turn off / not turn on again

 

I know that I sould look something like this

But on Z series is it accessible with just the removal of keyboard I dont want to do a complete diassemble.I dont think that is a good idea without a instruction guide..

 

The keyboard in the Z series requires then entire topcase to be removed, so yea removing the keyboard would give you access to the CMOS battery.

 

I opened up the hatch. The board is lying in front of me I couldnt find anything on the board that looks like a effected from a short circuit. Anything but the powersocket. I'm still not sure but there is a changing in the color tone. Ill take some photos and upload it in a minute. If its just the power socket I dont think that would effect the battery power right? it would only disable the charging. or my perfectly fine motherboard is dead. :/

PS: I plugged out the bios battery for a minute but didnt take effect. Do I have to wait longer than that?

 

Hi again. I completely dissasembled the notebook. I'm a bit experienced at these thigs but I'm always clumsy with these filmsy components I hope I can put it back together. There seems to be no errors on the back of the mainboard also and the capacitors seems to be fine too. I'm taking photos right now. I couldnt find any instruction manual so I just did it myself didnt take photos during the disassembly because of excitement sorry. Be patient photos are coming

 

There is a disassembly .pdf guide here somewhere. I would post it but it's file size is too large. There is a disassembly guide for Z11 and Z12.

 

that would be very nice to have that pdf if you can find please share the link because I couldnt find it no matter how much I've searched

 

http://forum.notebookreview.com/sony/531011-vaio-z11-headphone-jack-broken.html#post6861267 Post #2 has a parts guide.


I hate link hunting, so I posted it on MediaFire, here, http://www.mediafire.com/?93zpdb5b1uz8knx This is the disassembly guide.


Both of these manuals are good to have.

 

@Antec87

Thank you for helping. I actually dont think my motherboard or any component effected. I think my battery and my power socket is KIA @ that moment I plugged out the cord. I closely looked in to the mobo there isnt any sign of damage anywhere. So if anyone has an idea please share I'm thinking to replace the powersocket you can see the color change. It looks like it burned.

Here are the pictures:

Try a voltmeter at all?

 

I got both the Z11 manual and the Z12 manual put in the specs / disassembly sticky btw
Easier then hunting through threads for them

 

After today I am thinking about that but I dont know which part to look and what voltage numbers I would be looking for. If thats not gonna solve My father has the exactly the same Z notebook. I am thinking about replace the parts one by one (rams-optical drive-keyboard-ssd- I/O interfaces and so.Which are completely fine IMO)After that I am thinking about replacing the mainboard and try to make it work.But I am a bit worried to damage the other Z too =/ But first things first I will compare the battery and adapters with a voltmeter I think the only problem is he is out of the country right now and wont be back for 1.5months. I think I have to wait until then. I am very gratefull to all who tried to help me and willing to help later.

 

I don't see the 10mb disassembly guide for the Z1 that I have on mediafire.

 

PM Rachel and get it added, i was meaning the manuals not the pull apart since I didnt have that

 

I should have used the voltmeter before. My AC adapter is fryed I think. I read something 10-11 with the voltmeter if I didnt used it wrong. The green led is on but that isnt the sign of it is working fine right?. And on the battery connector I can smell something like burn. maybe they both fried but I dont think it effected the board because It seems just fine I dont understand. I really hope that would be the situation and I am ok with the whole disassemble for nothing =) just want my perfect laptop working back.

 

If you have another power adapter (same voltage output, and same plug), you can remove the battery, plug into AC, and see if the rest of the Z is okay.

 

^+1. I wouldn't assume your adapter is bad just by the low voltage reading. These adapters get smarter and smarter to avoid overvolting units and it wouldn't surprise me if it starts off at real low voltage until it detects some sort of load/pattern and then responds with 19v output.

 

Ok then I will try with another AC but I dont have any exact Z series adaptor. There are F series users around me and their AC is 19.5V 6.2A I think. Vaio Z is 19.5 - 4.7. If I plug in this AC is this cause any problem any idea? Or should I look for a 19.5- 4.7A AC adaptor?

 

My worry is that there's a short circuit on the Z, which means the power adapter might be negatively impacted. You could try checking the resistance of the Z (via its power terminals, where the plug goes in). If the resistance is 0, then I *think* there's a short.

If everything's working properly, the larger amperage should not matter...

 

I dont remember the resistence without the plug out on the power terminal(I've checked the plug today with voltagemeter) But with the plug in there is a current which is 5.0V I think. Tomorrow I'll check it with the F adapter and I'm at the university so I'll ask about voltage readings to my electrical and electronics engineering studying friends. I'll send in the updates tomorrow then..

 

6.2A adapter is fine. Your pc will only draw as much amperage as it needs. Voltage is what you need to worry about (but not in this case).

 

I've got an AC from my friend it is exactly the same Ac 19.5V 4.7A. But the laptop didnt power up again. I'm starting to think there will be no happy ending to this story :/

 

It's just not happy, yet. The work you are doing is great, and the learning process along the way is invaluable. Keep up your hard work. There is always a light at the end of the tunnel.
