Solved Replace main board and processor on Vaio VGN_NR140E

October 3, 2013 at 17:49:53
Specs: Windows Vista
In a bonehead move I pulled the ram chips out of my laptop to upgrade from 1 gig of ram to 2 while it was in hibernate. It apears I damaged the main board because it won't boot up. The ram chips are ok because I put them in another laptop and it boots normally.The computer is very slow and I was looking to upgrade by installing a mainboard with a 64 bit processor and maybe 8 gigs of ram. Any help would be apreciated.

Of course - we're just making an educated guess that it's the motherboard...
If you have have money to throw around and enjoy a challenge, then go for it.
You have nothing to lose (apart from $100 and a little hair).
Otherwise cut your losses and put the money towards a decent replacement laptop.

Have you stripped a laptop down before, or reassembled one from it's component parts? It can be tricky and frustrating, but a good learning experience, even if it doesn't work. (Often it's a case of, "the operation was a success, but the patient died"). ;o)

Let's know how you get on.

Intel Pentium dual-core T2330 ? As with most of the Pentium dual core CPUs, its already 64-bit compatible.
The maximum RAM your model will take is only 2GB.

It's an older model (2007?) - a good workhorse maybe, but
1.6GHz CPU, 2GB RAM: it's never going to fly.

Unless you can get a working motherboard from a scrapped Viao for next to nothing, it's probably not worth the effort attempting to repair this.
I'm guessing it would also have to be a Mobo from the exact same model to fit your case, so, little possibility to upgrade.

Fine if you enjoy messing about (some of us do. it's a hobby) but otherwise could be a lot of time, money and effort to get back to where you were?

Maybe time to look around for a replacement? ;o(

"The computer is very slow"

It's slow because you only have 1GB RAM. And I suspect you probably need to do a lot of housekeeping (run a cleaner, manage startup apps, defrag, etc).

"I pulled the ram chips out of my laptop.....while it was in hibernate"
"It apears I damaged the main board because it won't boot up"

Obviously messing with hardware while the laptop is still powered up was the wrong thing to do. What exactly does it do when you attempt to power it up - any lights, beeps, sounds of the fan spinning up?

Totally blank screen, the processor light comes on for about 2 seconds goes off leaving only the power light on and then nothing after that. I attempted a disk boot with same results. There are no sounds and I cannot hear the fan running which is not normal on a boot up.

I ran across a blog where someone upgraded the exact same computer ( Sony Vaio VGN-NR140e )with t7800 duo core 2 (meron) 4mb cache 800mhz and 4 gb Ram. He was very satisfied with the computers performance. I can get the mobo and processor for less than $100 and I already have the Ram. Do you think this computer is worth it.
