I haven't really messed with the DIMMs yet (well as a starter, this laptop isn't exactly the easiest to work on, but I've seen way, way, way worse thankfully), they're still the original ones that came with the machine, although I swapped them (DIMM 1 in slot 2 and DIMM 2 in slot 1),when I got the laptop (as only 128mb was being recognized), I'll try cleaning the contacts with Isopropyl Alcohol and see how this goes.
If that don't work, I might just swap them for 2x256mB DIMMs and call it a day.
By the way, I found something pretty neat: https://www.hp.com/ecomcat/hpcatalog/specs/F2337WT.htm I wonder how HP didn't remove that page (as it's often the norm these days, they purged anything legacy, and others will follow suit, such as Intel 😵 good thing that the Web Archive wayback machine is a thing).
I've also seen that there was other models of Omnibook XE3s, of which I can't find anything about them, I'll list them here:
- Omnibook Xe3 "GC" (the one I have, seems to be the most common version, Intel Pentium 3/Celeron, S3 SavageIX/MV)
- Omnibook Xe3 "GD" (AMD Duron/Athlon? Frequency unknown, Trident CBXP Graphics w/ 8mb VRAM)*
- Omnibook Xe3 "GE" (AMD K7 Duron or Athlon)*
- Omnibook Xe3 "GF" (Intel Pentium 3/Celeron, Intel 830MG graphics (??)
About the GD and the GE, I could not find anything on them, the only reference I could find is in some kind of manual: https://www.manualslib.com/manual/71748/Hp-Hp … e3.html?page=18
But I also found this chart (from some HP documentation) showing the different Omnibook Xe3s variations, it's sure handy given that the XE3 is a obscure system!
