Laptop won't start after memory upgrade!

by 2004 GT RagTop / February 23, 2009 12:00 PM PST

I have a Sony Vaio S460 laptop.

Recently it had been lagging really bad, and so I was advised that it might be a power supply problem, or, another solution would be to upgrade the memory.

I went to my local computer store asking about it, and he recommended trying to upgrade the memory (I currently had two 256 MB memory sticks, for a total of 512). I told him my model number, and he pointed me to a Kingston 1 GB memory stick, and said he was pretty sure that it would be compatible. Since it was only $10, I bought two of them.

Ok, so I went ahead and replaced the two 256 MB memory sticks with my newly acquired 1 GB memory sticks. But after I put the laptop back together, and I pushed the power button, nothing showed up on the screen (although the lights indicated the power was at least on).

I went back and replaced one of the 1 GB with a 256 MB, but now in addition to the blank screen, it wasn't even showing the light that power was on!

At that point, I went ahead and put the other 256 MB stick in (so this would be how it was before I upgraded), and again, it wouldn't even turn on!

I took out the memory stick from inside the computer, and tried to have the computer turn on with just the 256 MB in the other slot, no luck. I tried to turn it on with the 1 GB in the other slot (and again, leaving the other slot empty), and still, no power!

What's going on?!?! I really hope it isn't something major, but I don't understand how it could be considering all I did was swap out the memory sticks, and even then, I went back to how it was and still no power.

I'm stumped.

Sounds Like It Was The Power Supply Then...

It's quite possible the two larger sticks of RAM "broke the camel's back" and the power supply died. My next stop would be the repair shop.

Hope this helps.

Oh geez, I hope that's not what happened.

Here's an update, and I actually may be one step closer to figuring out the problem, though I don't know what to make of the following:

I took the battery out and any other connection, and held the power button for a few seconds. After that, without reinserting the batter, I only connected the adapter to the laptop, and it turned on! I have the new 1 GB or RAM, and it was recognized on my computer. So, at that point, I thought I was in the clear.

Except there still is a problem. I shut off the computer, reinsert the battery, but I was back to the same problem where the computer wouldn't turn on! So I figured maybe it's a bad battery, and since I have another one, I went to try the other. Still didn't work. I unhooked the adapter, took out the battery, held the power button for a few seconds, hooked the adapter back in, and again, the computer worked fine.

What's the problem? How could both batteries be bad? When I initially tried to put the two new sticks of RAM, the computer would power on, but have a blank screen. After that, I didn't get anything. I may have changed the battery in both instances, but logically only one of then would be bad at this point since the computer didn't even work except for that one time.

Something similar happaned to me once

In reply to: Update

I had to send in my laptop for service, and I wasn't going to send in my 2gb RAM with it to get lost, so I switched out my 1 2gb stick and put the two factory sticks back in. I tried to boot it up to make sure I got everything off the hard drive, and my laptop was pretty much comatose. The lights came on, but that was it. Black screen, it wasn't processing or anything.

When I received the laptop back, I switched out the 1gb for my 2gb, and the damned thing took almost 15 minutes to boot. I ended up getting a replacement notebook, but I still don't know what happened with the RAM. That 2gb stick is in this computer as I type.

I've heard something about static electricity doing serious harm to a computer when it's open, and I wonder if I did something to it when I switched the RAM.

This might seem like a dumb question and please don't take offense, but are you sure you're putting everything in right?

If you know someone who would let you, I'd load up your new RAM into a compatible laptop and run a memory scan on it. I did that with mine after I had my issue, just to make sure it was working right. My RAM is Kingston as well, and I know they offer a lifetime warranty on their RAM.

Anyways, I don't know a whole lot about computers, but I experienced the same issue. Good luck
