Black screen - what's the cause?

Nov 12, 2005 2:36AM PST

I have a Toshiba Satellite P25-S607, running Windows XP MCE. I normally don't shut it down, just leave it running and close the lid to send it into standby when I'm not using it. Generally it runs very well -- I can usually go a couple of weeks at a time before I need to shut down and reboot (you know, to clear out the cyber-cobwebs Wink ).

The reboot is where the problem sometimes comes in -- this was originally very intermittent but is becoming more frequent. If I shut down and then reboot by pressing the power button, as often as not I'll just get a black screen. (More recently, this will sometimes happen as well if I choose Restart as opposed to a full shut down and restart by the power button.) When I first push the button, I'll see a split second where the black screen is backlit and the hard drive indicator light indicates hard drive activity. Then the backlight disappears and the hard drive stops spinning -- I can hear the CD drive spin up and the fans running, but that's it. This will happen repetitively, but if I walk away and come back later it will boot up without a problem. I've wondered if this indicates something is overheated, but I don't feel any real hot areas on the case. My thought was that the hard drive might be going bad, but once it's gotten past that first few seconds (is it going to boot up or isn't it???) it's fine, no problem at all with hard drive activity. I've also heard this may also indicate a motherboard problem. I'm not sure how to proceed as far as diagnosing/troubleshooting, but with the problem becoming more pronounced I feel some urgency to get it taken care of. If anyone has any ideas about this, I'd greatly appreciate it -- TIA!

Did you make the call?
Nov 12, 2005 2:56AM PST

Toshiba has some models that need BIOS updates, motherboard changes, driver updates and so on. Their service centers usually cover this if you call in.

Your post tells of the usual issues but didn't reveal if you made the call, researched Toshiba's web site and if you are sure there is no pest, SONY ROOTKIT (google.com), virus, trojan, spyware or such on your machine.

Cheers,

Bob

No I didn't, and my reasons...

Hi Bob --

No, it never occurred to me to call Toshiba on this. I bought this machine previously owned last winter and it was already out of warranty. That being the case, I don't think I'll be able to call for support without having to pay for it, and I have no interest in sending it away to Toshiba for repair -- I'm hands on enough to handle changing out a hard drive, and if work is needed that I don't feel comfortable doing myself, I'll pursue having it done locally. Really, I was just hoping someone might recognize the symptoms I've described and be able to tell me without too much hassle what the problem is or how I might easily do some preliminary troubleshooting.

Also, here is the other information you requested (I'm sorry I didn't include this when I first posted). I feel certain I'm not dealing with a virus, trojan, or spyware/adware. I'm very careful about keeping my antivirus definitions up to date, and I also scan regularly to eliminate malware -- my machine is clean as a whistle! Happy I've searched through Toshiba's web site but have found nothing that addresses this specific problem. I also run the Toshiba Software Upgrades utility regularly for available updates, and everything is current. Really, this doesn't strike me as a BIOS or driver issue -- given the fact that the problem has been sporadic and has increased slowly but steadily from extremely infrequent to semi-regular, my gut feeling is that it's a slow failure of some hardware component. If you or anyone else can offer further thoughts or advice, I'd appreciate it -- thanks!

A for instance.

There were some models that needed a speaker grill replaced because a static discharge would lockup the computer. If this was never accomplished, repeated discharges will damage the chips on the mainboard and a black screen will result.

The call should cost about the toll or toll free charges to find out if your make/model had this issue.

The fix for that was to fix the speaker grill and if the damage extended to a dead motherboard, then you replace the motherboard.

It appears the other items aren't in play yet since you have no display at all. Most local repair shops didn't know about the static issue and none that I know of knew what to do about it.

Thanks for the example -- I see the point of calling Toshiba now. If I can get this problem sorted out, I'll post back and let you know what's causing it. Thanks again!
