Laptop_Nerd :
Hi,
Please do try these other troubleshooting steps that may help.
- Start with a hard reset, remove the battery and AC adapter then press and hold the power button for 20 seconds then try powering it on.
- Reseat the RAM, remove them all from the laptop for couple of seconds then put them back in making sure that it's seated properly into each slot.
- Lastly, use another AC adapter that has the same voltage with yours just to verify if it's the motherboard or the AC adapter because if the laptop will still not power on using a different AC adapter that means the suspect is the motherboard.
LN,
Thanks for taking the time to help me resolve this issue.
I tried each of your suggestions, but, unfortunately, the problem persisted without any change.
I have one question regarding the unpowered hold on the start button. Since the only power left is the Bios battery, Im guessing this is a method for resetting the Bios. If so, thanks, thats a great tip! I can definitely see it as a practical feature for laptops when jumpers on the MB become unpractical, but do desktops have this feature as well? Also is this exclusive to Sony PCs or has it become a standard feature for PCs in general?
After reading your suggestions as well as some similar posts I found elsewhere, I might have some more details to offer that could help narrow down the probable cause.
First Id like to eliminate some issues that involve PC crashes such as improper seating of RAM or BSOD. After the display stopped working, early on, I was still able to login in in the dark to hear the Windows startup music, so the PC was at least booting.
I did hear a beep code of a short beep followed by another short beep which, I believe is normal.
I saw in your post as well as others that it could involve a PSU issue. I didn't have a compatible adapter but I could boot from the laptop battery with the same results.
Re: the power supply, this got me to recall that I had noticed that the laptop ran pretty hot only seconds after powering on. If the PC was working, then the state would have been before the Bios login to the hard drive at the very beginning of the boot up process, or at the windows login if any of by Bios reset attempts worked. I know that this laptop can run very hot if I stress the processor over a length of time, but to do so at the first login doesn't seem probable because it cant even load software to stress the CPU at that point having no access to the OS Hard drive.
This lead me to thinking about hackers possibly overclocking the CPU or GPU or both. Then I remembered that the one successful startup without a monitor seemed extremely quick to say the least. I couldn't do much about it at the time nor could I repeat the login for some reason. With hackers attacking me nearly 24/7 for a year now, strange things become the norm and difficult to remember or even take the time to take notes in a notebook so sorry for neglecting to include these facts.
BTW, Im not interested in security advice unless it pertains specifically to what I will be discussing below as I don't want this issue to get sidetracked over generic security advice.
If a very skilled malicious hacker wanted to brick my machine and assuming they could hack in and download what ever tools they needed, could this be a result of overclocking both processors? Perhaps causing the GPU to fail while running the CPU very hot on startup?
Ive never tried to overclock any machine and am a bit clueless at where to start investigating into this possibility.
Is there any way I could verify overclocking using another machine?
Any chance to recover if the problem was overclocking? Im hoping that some kind of safeguard might be shutting down the GPU before any damage is done.
If I was to search the hard drive on another machine, what could I try to look for as evidence for overclocking processors? Would they be required to be installed into the system and could you tell me what the path might be in?
If they can be run as portable tools with disguised names, perhaps any unique extensions I could search for?
Any Windows logs , drivers, registry entries, etc that I could look at assuming I get a monitor working for that boot drive, that is?
Also, could I boot up from that boot drive on another physical machine without incident if I ran that system software for allowing boot drives to run on another machine? Sorry, forgot the name. Ive only used it for crating live boot drives.
Im running Windows 7, Pro, 64 bit
Finally, bear in mind that I have this equipment to work with:
Vaio laptop with no working monitor and Neither HDMI, or VGA ports are working. Local Boot drive is SDD.
I have a working desktop but Im not sure if I could boot it from the laptop drive. Any tips if I could or should do this?
Desktop: Windows 7, HP 64bit.
All of my live drives or repair sticks have been disabled, but I do have Windows Installation DVDs.
edit to add:
I imagine I could run the laptop SDD drive as a slave HD On my desktop. Are there issues with making this work as in, are their SATA compatibility issues? or with any power connections required? I also have an external HD with USB3 that could fit everything from the laptop HD, but I don't know how Id be able to copy it using the laptop and I haven't been able to repeat doing the login in the dark for some reason.
Im Just speculating, but my guess is that hackers are currently able to access the laptop through an unauthorized (at least by me) Wi-Max connection. However, I'm not sure how this might help for resolving this matter.
I realize this may require a separate thread once I verify that it's an overclocking issue. Again, thanks for your help in this matter.
