1998 Toshiba Satellite 1605CDS/4.3 Will not stay on!

[Vitam]

I love old computers, so I purchased a Toshiba Satellite 1605CDS off eBay in MINT CONDITION with the carrying bag and a mouse! It came from the original owner, they never had issues with it. It had worked great for the past few months, but last night, I restarted from Windows 98 to Windows 2000, and it got stuck booting 2000. No big deal, old computer, I thought. So I restarted it, and it worked for about 3 minutes, then shut off! It then started to turn on (fan at top speed, some hard drive activity) then it shuts back off. Back on, back off. Stays on for about 3.5 seconds each time, off for about 2. It keeps doing this unless I unplug it, and plug it back in, then it works for another 3 to 5 minutes, then that happens again. How can I fix this? I'm hoping it's the power brick, as it is the original.

Tried removing the battery? Might fix it.

I would remove all peripherials, reseat RAM, remove and reconnect CMOS battery (might be in the RAM comparnment) and try to turn it on. Obviously only with power adapter without main battery.

I took out the battery and it still shut off after a while. I will try gabik111's suggestion now and tell you how it goes

I can't locate the CMOS battery.

i'm confused,
are you saying it's a dual-boot setup, or you where upgrading to win2k??

I can't locate the CMOS battery.

No reset jumper in RAM bay?
Well, I'm not familiar with this laptop but there should be somewhere. Underneath keyboard maybe?
I know that there is a dip switch somewhere (under keyboard I think) to clock CPU and set CPU voltages in this laptop. Maybe there is something more near this?

There are some dip switches, and it dual-boots 98 and 2K

I completely disassembled it, located the CMOS battery, even replaced it, to no avail

I'm thinking the laptop is just toast

Also, the dip switches are right next to the CPU underneath the keyboard. No reset jumper anywhere.

If you disconnect CMOS battery no need to find reset jumper. Looks like fixing it becoming more time consuming than money. How power adapter behave? Does it keeps voltage constantly during that on/off period? I would start with schematic and power section of laptop looking for bad caps.
Anyway win2000 might require more CPU power than win98 so this will lead that power section might be too weak. Try to boot it to win98 and see what happens.
