Re: [X230] Magnesium body repair

How much of structural stuff do you have to repair? Like if you just mean the magnesium bottom chassis palmrest corners are cracked that can be repaired with epoxy. From my experience there are epoxies that work best on plastics and there are epoxies that work pretty well on metal, but takes ages to...

Re: X2100 loses bios settings if left unplugged

I'm struggling to reproduce the issue now. I swapped the BIOS battery, and the old battery had 3.11v so I think that rules it out being flat? I learnt something new too, I didn't realise the BIOS batteries were not rechargeable, I thought the machine charges them whilst it was powered on, but infac...

Re: WTB ThinkPad with 4:3 And XGA preferred

I actually have both a Dell Latitude D520 and a HP Compaq nc6320. Both feature the same 945GM chipset as the T60 - but these support up to 3.25-3.3GB of RAM rather than 3GB due to better optimized BIOS. Unfortunately for you, both are also equipped with 15" SXGA+ WVA displays so I am gonna have to d...

What kind of specs are you after? Yes 14.1" XGA screen but do you want it Pentium III era, Pentium 4/M era or Core duo Core 2 duo stuff? If you say you want T60 T61 specifically then you want Core duo Core 2 duo stuff I am assuming?

Great idea - Do you happen to know what the voltage would be for a "good" cmos battery after a few days storage? I'll leave mine over the weekend then grab the multimeter and I'll start by seeing if I have a parasitic drain. I can compare to my original X201's CMOS battery too. A highly charged CMO...

I don't own these but I believe a more "silly" testing method is if you have a bench power supply go and supply 3V to the cmos battery connector and read the power draw. If what you're suggesting is that the CMOS battery runs empty after just a few days (and that the CMOS battery is actually deplete...

The chin on those screens is EXTREMELY sensitive, if any part of the chin is being touched or mangled b...

Re: T43 wont turn on

Well if you have a battery installed the battery LED should do its thing (yellow if the battery is charging or dead, green if it's almost charged or charged). if your motherboard isn't even going that far then a new keyboard certainly won't help you much.
