No power i have a sony viao s5 notebook.It suddenly stopped powering up,charging?even when i remove the battery and connect straight to a/c.Nothing,please help?

remove battery and retry with only ac power connected ..if that works then the battery is bad...if that doesnt work then it could many other things like bios battery, power connector, mobo...

Hello.

The most common reasons for power issues are the battery, power jack and power adapter/cord.

Since you already removed and reinserted the battery, try the other options.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.

The power jack is inside the laptop and either needs soldering or replacement. If a power jack problem, it should be addressed by someone knowledgeable.

If no change, the power adapter is probably faulty and needs replacement.

Hope this helps.

Disconnect external devices. Remove battery and power cord. Then reposition them again. Be sure battery is locked with the switch at the bottom of the unit. Keep charger connected. If issue continues it may require service.
If you can see VGN-CS on the upper left corner of the lid (your unit's model number) you will need to call Sony as this is a known issue

Are you using a Sony Battery or an aftermarket cheaper version?
If your battery has been changed to a different brand then thats your problem and a whole problem in itself.Not saying there is anything wrong with that, but the Sony ISBmngr.exe file will stop the charging of any battery exept Sony's and put the system into hibernation mode. ( website with Info below)....
If you have the original manufacturers battery then go on.

This is the typical charging-plug, jack, for laptops. Many times the plug itself is bumped over time and pushes on the pin in the center. The charging time becomes very short, if at all, because the connection is broken.Some are completely or because of the position of the wire holding it just right long enough to give a short charge.

With a Voltmeter ,check the output of the charger itself to be sure it is working properly.
Although VIAO has been out for a while & because the model was not listed here the age of the battery may also be in question. If the battery has shorted out and the charging unit & jack are fine then a bad battery that has shorted will cause you symptoms also. Try removing the battery and running on the charger alone.
Here are a couple of sites that I found that deal with Sony VIAO's

remove the battery and unplug the power. Hold the power button for 90 sec, do not plug in the battery yet. plug in the power and turn it back on. If the problem persist then it sounds like the motherboard is bad. Either replace the MB or part out the Laptop piece by peice and use the money to buy a new one. You get way more if you part it out then to try and sell it broken.

u r laptop battery has dead u need to replace it

Replace the power supply.

Sir,
you remove your Laptop main battery and adaptor for aprox 10 min then fix again battery and adaptor then on power button m/c is on.

you may have a faulty motherboard connection, but try connecting the power adapter in without the battery and see if it runs, then replace the battery back in the compartment.

no i think the battery is dead >and contact vendor and replace it sure its under warrenty>and always use power stripe or surge>and check if u got a fluid leaking on the battery it means the battery is dead and i think u can remove it>and also i thing u have power adapter which u can use directly from power scores so try connect it
