I hear Win 7 startup, but nothing on screen

July 17, 2011 at 16:47:40
Specs: Windows 7, Service Pack 1 , AMD Athlon II P340 Dual-Core Processor 2ghz, 3 gb RAMmr
I have a Sony Vaio series E laptop with Windows 7 installed. I recently had an infection that led to my hard drive being replaced by Sony. About a week later, I began to experience a random problem when I would try to boot my computer. Sometimes it worked, no problem. Other times, I could hear hard drive activity and see the lights flashing, I'd even hear Windows startup... but it was as if the laptop monitor never turned on. Not knowing what to do, I press down the start button to shut it down and try again. Sometimes it would boot up properly right away, other times it would take 2, 3, 5 or 10 times before I'd see anything on my screen. Any ideas on what I can check? Any feedback is greatly appreciated, thank you!

Based on actually hearing the Windows Logon music and not seeing any picture, I agree with your assessment in that the monitor is not turning on.

Assuming your laptop is still under warranty because you recently took it in, I'd recommend sending it in again defining the new problem. Laptops are much more complicated to dismantle, especially because so very different from one to another.

On my laptop, I have a number of screws of varying size before I can pull up the keyboard. Once that's done, I can disconnect and reseat the monitor plug. Fortunately, Dell provided me with a detailed print manual for disassembling my computer. Maybe Sony did the same or there's one online?

Apologies if I don't respond to your reply immediately. I don't check this site daily, but you're welcome to PM me as a reminder.

send it back, they obviously didnt connect something correctly.

you could open the drive panel and memory panels under the laptop and check connections are good, its worth a try and easy to do.

but this sounds like a graphic connection is not tight to me.send it back.

Mackgem, did you try an external Monitor?
If that works ok, then your Laptop screen needs to be replaced.
You must press a key combination to toggle between Laptop screen and external monitor.
Usually it is the Fn key and an F key.
On my Lenovo it is Fn + F7
I had exactly the same symptoms on my Lenovo and my Computer store replaced the screen for free. Usually it is an expensiv job.

Thank you for your advice, that sounds like a good troubleshooting tip. I'd like to be able to eliminate or determine if it's a possible cause before calling Sony tech support, but it'll depend on how long it takes me to try that out. Unfortunately, I'm in a one computer (and monitor/connector) home.

I appreciate your reply. It is still under warranty, so I'll be giving Sony tech support another call... I just have to get motivated to do another hour-long or more call as they take me through all the same drills that have already been done. It'll be necessary though because even though they sent me instructions to replace the hd, and I believe I did everything okay, I'm still left wondering if I did something to cause this new issue.

Thanks for taking the time to answer my question. I'd love to tell them they didn't do something right, but unfortunately I was the one who was sent the hd and instructions. If anyone knocked something loose, it would've been me.

I have a new discovery, however....

Earlier I mentioned that it's random as to whether or the laptop boots up on the next attempt, or any other number of times I try to start it up. Well, one thing I've noticed is that when I remove my battery pack for a couple minutes and then slide it back in...it almost always starts the next time. I don't know if this is just a weird coincidence or if that can reveal something more into what's happening?

ok you bought a laptop, its under warranty, you followed the manufacturers advice and installed a harddrive, its still not doing the job you bought it too do, while its still under warranty, call them and demand an RMA, if you bought it from a stopre, call the store and request an RMA, dont mess with it, its still under warranty.. DEmand a replacement.. stick too your rights you obviously have damaged goods.
