Main Topics
Browse All TopicsI have Sony Laptop PCG-TR2AP with Windows XP Professional, CD RW and No Floppy Drive.
And it is DEAD!
I had copied all my data from both the C and D drives onto an external USB hard drive and deleted all this data from C and D of the laptop.
C has all the system files and D is fully empty.
And the laptop was working normally.
I installed Personal versions of Oracle 8 database PL/SQL and Developer 2000 software on the D Drive. I tried uninstalling using the Oracle CD but failed. The devil asked me to delete the 2 folders containing all the Oracle files which got created during Oracle install. And I deleted these 2 folders from the D Drive but did not empty the Recycle Bin.
On reboot, when I press the power button, the power light goes on, the battery light, hard drive light and the CD drive lights flash and go off.
Apart from the above, nothing else happens. At boot up , I put the BART Bootable XP CD in the drive but the drive just spins and nothing happens.
I put the Windows XP CD with s/Pack Disc 1, the CD spins, but nothing happens and same with Windows XP CD Disk 2 of 2 - Diagnostic.
The screen is totally blank and dark as if the laptop is off.
Any ideas?
PS: I have NO data in the system.So I could do anything but I need to get INSIDE the system somehow. Once I get in, I could restore the 2 Oracle Folders from the Recycle Bin back to the D Drive and it should all set.
Thanks

I can't see this problem being caused by what you did.
It seems like a power problem (battery/AC supply) or possibly a fried processor/motherboard. Maybe the BIOS got wiped out. Again, I don't see why this would have happened based on what you did.
Maybe just a coincidence.
If you can confirm that the batt/AC adapter are good, it may need to be sent in the the manufacturer for repair.
Here's a link with a procedure for power problems from Sony. Try these steps.

Well the link got broken up. Try this one and go to the on Power Problems (last one it the top section)

Gary
Have you tried letting it charge for awhile and then trying again? Sometimes, I've known laptops that wouldn't start just needed a bit of charge in their battery even if the AC was connected. If the XP discs don't work, can you try another bootable CD such as the Ultimate Boot CD or Knoppix? The Ultimate Boot CD (DOS version) has a lot of utilities that can detect hardware problems.

Did you run through the steps here:

for power issues?
Gary
This could be an issue with the laptop's LCD screen. I have had screens go bad on sony vaio laptops. To check to see if this is the case, if you have a desktop monitor and a VGA hookup in the back of the laptop, you can hook up to the monitor, boot the laptop and if something displays on the computer monitor, your problem is with your LCD screen or its connections. (I have had to have cables and LCD screens replaced before.) This is just a thought and it may not be related at all, but I thought I'd throw it out there. Good luck!
I think if it was a display problem that you would still see/hear disk activity if it got to the Windows boot. It would still be worth checking. If it's failing POST/BIOS setup, there may be a message there that you're not seeing.
Another thought I had was the internal power supply (after battery/AC) may have partially failed. I've seen desktops lose the 3.3V supply (sagged to 1.7 under load) and the fans/drives would still spin up but no boot. Unfortunately testing the internal voltage levels on a laptop is a lot more difficult than a desktop.
Have you tried holding the power button for 15 secs, or the reset button on the bottom. The link above also mentioned to try removing memory.
Gary
I removed both the memories and pressed the power button, nothing happened, powered down, put back the memories and pressed them HARD, real hard into their slots and then again from the top after the latches fell into place.
Again pressed the memories, closed the cover and powered on.
VIOLA! It booted up without any problems.
I went thru the same process earlier even before posting here and had failed, but this time it worked. Dont know how or why.
I will try to give the points as fairly as I can.
Thanks for every one in trying to help.
Gary's link ( though I never really tried all the steps mentioned in there) but most importantly his last post where he mentioned trying to remove the memory was partly useful as I had done the same even before posting this problem.
With sincere appreciation for all others in coming up with different ideas,I would like to award points to Gary.
Rest others, please do keep helping people, points are not the end-all for everything.
One more question:
I feel the base of the laptop is getting over heated as sometimes it gets sort of burning hot though the fan rotates.
I have never come across any laptop which gets so much heated.
How could I measure the temperature and how can I solve this over heating problem?
( No points for this question though).
Sometimes there is an environmental monitor in BIOS setup that can tell you the internal temprature and in some cases allow you too enable alarms if it gets too hot.
What's "too hot"? That's a good question. I used one for a while that would get uncomfortably hot when setting on my lap. Just make sure all the vents are clear.

Do you see the Power On Self Test, or BIOS setup options? Is it having this problem with the AC adapter attached? Do you have a way to test the AC adapter?
