I am having a similar problem with my 600m. Mine will run for about 5 to 10 minutes and powers down for no reason. This occurs without the batteries installed, running on A/C power. I've checked the voltage of my power supply (it was within .05 volts of what was listed on the adapter with no load) and even tried a different one for the same computer. It shuts off when using batteries only. I have both the normal battery and a drive bay battery, and any combination of batteries and A/C adapter results in the same issue. The issue with mine started when I was working on the laptop, and noticed the batteries were at about 50% power, so I hooked up the A/C. Several minutes after doing so, the laptop shut off and would not reboot. The power light would come on for about 3 seconds, then go out. After cooling for about an hour, it restarted, but only briefly. This problem has not gone away, and of course Dell doesn't want to send someone to look at it under the extended warranty. They are saying that because it was purchased on eBay from a retailer as a Dell Factory refurbished unit the warrany is void. Since it seems like a heat problem, I decided to crack it open to investigate. The hinge cover snaps off easily. That's all I had to do to see that the heatsink for the video and northbridge was severly blocked. After cleaning it out, I was hoping for things to be back to normal. No such luck. I have even taken the heatsinks out, and used some heat sink compound in hopes to transfer the heat from the processors more efficiently. No dice. I have searched for days trying to find a utility that will monitory MB and CPU temps, but every one that I download only finds sensors for the HDD. The BIOS does not have a temperature monitor that I am able to see. It is revision A17. The motherboard model is X2035, rev. A01. It has a 2GHz Celeron CPU, 64MB ATI Radeon VPU, SXGA display, 1GB RAM, Intel Pro Wireless... It did seem to get pretty hot. I am wondering if it has to do with extra heat generated by the second drive bay battery. I have a second 600m, which is dead. Similar turn of events, but when it shut down, it never restarted... Board model Y8639 A00. Same specs. It also seemed to get very hot. Of course it died just month after the warranty expired and Dell would not give me any good will on it. So that's my story. I'm not happy with Dell right now. Currently I'm on a Gateway M460E and it runs much much cooler. Unless Dell helps me out, I'll probably part out both laptops and get another one of these Gateways.
