I agree with micromend on the clone power supply. It sounds like perhaps the voltages aren't right or the wave form is messing up the power parts of the laptop.
I dont necessarily agree about the cmos battery but then Toshiba could be different then the ones I have used in the past. I havent tried it lately but you used to be able to run computers with no cmos battery at all. it just meant you had to redo the date and any custom bios changes at boot up. Please clarify this micromend. You cant boot a toshiba with no cmos battery?
I have a bad battery in one of my old compaqs and it still works. just have to set the date whenever I boot it up. (I been lazy to take it apart despite having piles of these batteries laying around lol)
Hi
Once before I had a similar Toshiba come into the shop. Try turning the unit on without the battery installed and on the good Toshiba charger. The computer batteries have a minimal current level and once power has gone below this level they will cause all kinds of problems. If the Toshiba now works, you're home free - just replace the battery. If it doesn't work then it will have to see a reputable repair person who can troubleshoot chip issues. I've seen these clone power supplies do all kinds of things to computers.
Hi
Yes you can boot virtually any computer without the CMOS battery, but as you said you'll have to put in custom settings and date/time. On RAID machines this becomes a real pain but each time you boot you have to have the raid drivers available to be read. I've never worked with an IGO charger but as I said the generic chargers cause different symptoms. I use a Gateway M530 which works just fine on my Gateway charger but I've tried putting it on a generic charger with the correct setup and I get a whitish screen with only half the characters showing. Something weird. A reputable tech should be able to repair those mother boards. Good luck

Your issue sound as though the mother board battery needs replacement.
The cmos battery has lost it charge and needs replacement. this is possibly why the computer will not post.
This will require you to disassemble the laptop. You may also have a defective laptop battery. Laptop batteries last about 2 to 3 years depending on operation, sometime they are bad out the box.

No, the hard drive does not spin up, and it doesn't do the POST beep or anything. I tried it just on the battery, and pulled the batter out, and tried it with the known good charger.
I'm suspicious of the iGo charger. This is the fourth computer it has been used on, and in every case, the computer has died with the exact same problem this one is displaying: power lights come on, but won't boot up or show anything on the display.
And, I have already taken one of these apart. This is the 2nd model of this laptop I worked on. The first one developed this same problem. Got the 2nd one off eBay, to use "for parts and repair". Found a "tear down guide", illustrated with photos, showing how to take one apart. Got the 2nd one up and running by swapping the hard drive, DVD drive, and a few other parts from the "old" one to the "new" one, including the CMOS battery, which was reported as dead on the "new" one. Got it up and running, got Ubuntu updated, etc. Figured it was "fixed", so took it to the friend. His family had it less than a week before it developed the same problem as the first one.
As I say, I'm suspicious of the iGo charger. I don't know if it's a defective charger, or just that "universal chargers" in general are a bad idea. In any event, this experience has led me to remove anything associated with iGo from my "got to have" list.
I swapped the CMOS battery from another laptop the same model as the one I'm working on now. When I first got the laptop in question, it reported a problem with the CMOS battery.
It won't POST or start up at all, laptop battery installed or not installed. Only thing that runs is the CPU fan.
That's what I'm thinking: It's a problem with the iGo. That is, the problem was caused by the iGo, but at this point it can't be fixed, as the damage has been done. :-(
Sounds to me like an problem independent of the power supply. spill damage? bad bios chip? bad motherboard.? Does the hard drive light blink and spin up? Does it "sound" like it is booting independent of the monitor? Trying to rule out a monitor issue. you might be able to send the laptop in to a shop pretty reasonable if it ends up being a bad motherboard. I see some on ebay now and then that specialize in motherboards. it is cheaper if you remove it BUT if you aren't super techi inclined you might not want to try that. Ive been fixing anything and everything since I was just a little kid and I dont like taking laptops apart at all. they have tons of little screws and very tiny ribbon cables and it is so so easy to accidently break something, though I haven't yet but feel lucky.
