yet another sony vaio e series problem..

post #1 of 9
Thread Starter 
As the title says... Have a Sony Vaio E series laptop, windows 7 64 bit, couple years old, hand-me-down sort of thing we've attained. Well, go figure, now it isn't working right. It does boot and works perfectly fine, absolutely flawless. BUT, most of the time, when you try to turn it on, it attempts to boot but doesnt fully turn on, then is dead with the power LED blinking red. have tried all the fixes(remove battery, try different outlets, charger is tested working, battery was perfectly fine, took apart, connections are fine, HDD is fine, etc). No fix works. I'm going to assume this is a hardware fault, probably the mobo died. Can anyone confirm my suspicions? I've looked through dozens of forums and dozens of sites. an overwhelming majority of the "fixes" was complete idiots with just about ZERO knowledge of computers offering textbook advice on problems not related or saying stuff that would trash a perfectly working computer.... I'm about to just start scrapping it out as junk but want to confirm my suspicions first.

That might be an indication of what's going on. You might be able to figure this out by finding the service manual for your laptop and looking in the troubleshooting section for the meaning of the blinking led.

There's nothing in the downloadable manual from Sony's website that described the problem. it just gives generic error problems and says to have serviced by licensed professional, blah blah all that good stuff. looking through forums was just a bloody nightmare, too many ignorant people on those "help" forums... it's a very widespread problem that seems to affect most all sony vaio E series laptops. most of the time, it's a piece of hardware that dies for some reason or another. I've disproved all the other possibilities(bad battery, bad HDD, bad charger, bad RAM, bad connection somewhere, etc etc etc). I'm just not sure if there's a possible software issue that is a bugger to find and fix that could be the problem or if i should start gutting it for something more reliable and better functioning. it's becoming highly slow and problem ridden so the only thing holding me back is money from replacing it outright.

The only thing I can suggest you is to disassemble the laptop, thoroughly remove all the dust from the heatsinks and renew the thermal paste on the CPU/GPU/Chipset, hoping it's an overheating issue.

been there, done that. took forever but it was all okay. and the CPU was soldered into place so no go there. I'd have to remove i think it was like 4 solder points to remove it and no guarantee it would go back together without resoldering it all up so i didn't bother with all of that

Well, it looks like you've nailed it down to the motherboard, don't know if it's worth replacing it though....

Well glad to know I'm not alone in thinking that. Thanks for helping troubleshoot!
I'll prob just scrap what I can off it and use what's good for parts bin supplies.

southernyankey1970 I think it's a 16.x" but I'm not sure. it's the widescreen version of it. It's a family member's not mine so I'll check it out and get back. I don't have a single problem with that, though it won't be for a while since it is still partially functional and I don't have money for replacements yet. Stay in touch about that though! thumb.gif
