Laptop issue sony

Well was using it as normal one day all fine, next day orange charge light works but then it never powers up and repair agent stumped and laptop has inbuilt battery any hints

I would google the model number in the search bar with "problems" and see what comes up

One thing that will stop the POST dead in its tracks is a defective graphics card/chip and naturally there's no display. The PC normally emits one bleep if it has a bleeper.

Perhaps the OP can verify whether he means boots up the OS of if just the power light comes on or nothing at all.

Perhaps the OP needs to replace the power button.

That's really thinking outside the box

Just been given another Sony laptop to look at that powers on for a second then back off again, which looks like it's a motherboard issue. Seen a lot of sony's have motherboard issues and if your power button is ok, I think it is likely the issue here too. Unfortunately they are the most expensive part to replace in the hope it fixes the problem...

It's not that expensive these days. Mobos for older models can be found for less than £50 on Ebay.

Unfortunately it always seems to be newer models i'm seeing the mobo's go on. When I have looked up the price they have been a couple of hundred quid when it comes to the vaio's. Nice laptops but sony prices...

Yeah they're pretty expensive for current models. But after a couple years they usually drop pretty quick.

Shame though. I've not worked on servicing laptop internals for a few years, I always recall Sony's high end machines being exceptionally good but fairly mediocre in the consumer market. Then again I heard they were pulling out of the laptop market entirely?

IMHO it's the chip packaging changes that are bringing in unreliability. When most ICs were gull wing LQFPs (Leaded Quad Flat Pack) the Mobo could take flexing and heating effects in it stride as the leads cushioned the solder connections. Now with BGA (Ball Grid Array) packages there's much less tolerance to flexing. Unfortunately getting all the fuctionality into a small space has necessitated extreme miniaturisation. The only way to inspect the soldering on those packs is with X-Rays as you cannot see the connections.
