I too have a Dell XPS M1330 which I really enjoy and use extensively - seems since 3 win updates ago, win now shuts down the Nvidia (NV) GeForce 8400M GS - told me there was an incompatibility with a 3D service - not sure what that's about - but - it now will not boot. I had a message my battery was very low (this I knew) and the bios needed at least a 15% charge to allow the NV card to re-engage. Staples Tech declared it dead, my Dell contract expired,
I wrestle with fixing this vs giving up. I did get it a brand new Dell battery- and I got it to boot up (so much for tech suppot).
Its iffy getting it to boot up - I'm on it now, but who knows if it hibernates or I finish for the evening.
