Notebook (Sony Vaio) running XP won't start, boot; no lights

by alwaystouble / December 3, 2005 2:09 PM PST


New here (can't you tell... I come with a problem!)

Sony Vaio V505bx notebook will not start, boot.

Does not make any sounds of any kind.

Lights indicating AC power or charging battery do not light at all (yes, AC is plugged in and functional).

Anybody have any ideas?

Completely dead... what does that mean?

Thanks all.

What ever it is
by glb613 / December 3, 2005 7:51 PM PST

it's not good. Is it under warranty?

It's obviously electrical

And my guess would be it's either a bum power supply, or a burned out motherboard.

So, I'd say the other post is pretty much on target. If it's under warranty, get it fixed. Otherwise, it's probably easier to just get a new laptop, for what it'd likely cost to get fixed out of warranty. Sell the thing on eBay to help offset the costs of a new one a little.

i thought it would make some noise or something if it was a power problem.

it is no longer under warranty; Sony wants 699$ to fix system board problem...

maybe should sell and get new one?
or would it be cheaper to fix elsewhere?

In reply to: electrical?

Electrical problems include the lack of power.

So, if the system's out of warranty, it's going to cost $700 to fix, and new laptops can be had for around $700 complete with better specs... Unless you've got some sentimental attachment to that one, sell it to someone who might have the knowhow and desire to properly diagnose and fix the problem, use the proceeds to offset the costs of a new one.

Probably won't get too much for a non-functioning laptop, but it's still better than shelling out $700 to get it fixed. If you manage $200, then a new $700 laptop is only $500 out of pocket.

Good points. Do you think...

In reply to: Included could be electrical, like the actual, physical connection between the AC plug and the plug-in, or where the power meets up with some other part inside?

I realize that sony is going to charge $699 basically no matter what; I wonder if it is something power- electrical-related that could be fixed by someone else for much less...

could i use a meter on some location/part to try to determine if it is a power problem or the more serious motherboard problem?

Power problem
by stewart6 / December 4, 2005 7:17 AM PST

Hi I posted in your laptop post but in case you didn't read it the symptoms indicate a shorted battery (a common thing with lithium ion batteries. Remove the battery and run on the adapter alone and get back tome.

Thanks for posting...

I released the battery and plugged in the AC: still nothing: no noises, no led indicator lights showing AC plugged in or anything.

The AC adapter seems to be functioning as it should; it has an led on the plug (right where it goes into the laptop) and it always lights up when the AC adapter is plugged into a wall outlet.

thanks for the idea...

any thoughts are appreciated.

It doesn'take much to fire an KER.Get a meter and check the adapter output.

you should be able to find a schematic for your model on the web to help you tinker.

I have the same problem

I have the same problem,
My Laptop just wont boot,

Can anyone please help me out

Just try
by Themisive / December 31, 2005 12:09 AM PST

Checking the fuse in the mains plug before you start tinkering. Often you get bad fuses AND bad batteries at the same time.

Just take out the fuse and use an ohmmeter set on the lowest setting across them, if there's no response solution, put a new fuse in, if there is a response, solution put that one in again and THEN try to check the output (it may also be a good idea to see if the wall outlet is switched on as well)

Another Vaio that won't start.
by -NA- / January 25, 2006 10:21 AM PST

I haven?t had any problems with my Vaio for two years until last week when it failed to start. The power light lit up briefly and then nothing; no lights, noise, or anything. I took the screws out and tried the power again and it started. The unit was turned on and off several times that day with no problems. When the next morning rolled around, the unit failed to start again. Since I already had the screws out, I took off the keyboard and top cover and looked for any loose connectors. After about five minutes of fiddling, the unit started. The following day, I had a similar experience, as with the day after that. The only pattern I have found is that the unit won?t start when it is cold and that some amount of random fiddling temporarily fixes it. Tomorrow I will simply warm the machine in my hands, without fiddling. Maybe it is just a temperature thing.

Any thoughts?
