Re: R51e CPU upgrade

Thanks for your quick reply, George. Is any hack out there how to make the FlexView screen run on ATI Radeon 200M-based R51e board? As I understood by searching this forum, this might be some firmware/BIOS limitation only. Even the Radeon driver for T43p (FireGL V3200) is exactly the same installati...

Re: R51e CPU upgrade

New donor has arrived on my shelf - very hybrid ThinkPad IMO: - 15" version in a good shape, LCD label says T42p, but: - Motherboard is T43 with an ATI X300 GPU - LCD is not UXGA typical for 15" T42p/T43p units, but SXGA+ and definitely is a FlexView screen - CPU is 2.13GHz Dothan but heatsink/coole...

Re: R51e CPU upgrade

Thanks, I'll give it a try. Just a side note: R51e, although being a 533MHz FSB Centrino ThinkPad, is not suffering from HDD error 2010 when using non-IBM's hard drive, is it?

R51e CPU upgrade

Hi guys, recently, I have acquired really nice, near mint R51e - no scratches, no shines on the keyboard etc. It runs pretty nice with Alpine Linux and I found it only has a Celeron CPU which of course lacks SpeedStep, has a half of L2 cache compared to the proper Pentium etc. Now I have the opportu...

T420 and i7-4610M?

Hello,
I own a T420 ThinkPad and I have recently got a CPU which has P/N on it: SR1KY. Per Google, this seems to be 4th generation of i7 (4610M). The question is if I can use it in my ThinkPad T420 to get some performance boost? Currently, the laptop has a Sandybridge CPU inside.
Thank you.

Re: New project: ThinkPad T40 mobo to work with 533MHz Dothan CPUs?

For the operating system I'd recommend a stripped down Windows 7 with ati display driver version 6.14.10.6606. I've tried many light weight Linux distros on T40 and many of them do beat Windows in boot times but once the system is up and running it's surprisingly almost always been Win7 which offer...

Re: Upgraded T40 to SXGA, now have LCD earthquakes!

The problem is definitely not caused by the interferences from the inverter board. Running the ThinkPad with disconnected inverter and using the table lamp, I still can see the stuttering is still there.

Re: Upgraded T40 to SXGA, now have LCD earthquakes!

Can be the stuttering somehow caused by exposed inverter? I am not running the LCD with cover attached, only LCD on hinges, inverter connected to cabling etc. (I did not want to assembly it without initial testing).

Why are the high-end Pentium Ms so expensive? Looking at feebay, ie: Pentium M 765 (top processor for T40 - T42 series with Dothan core and 400MHz bus) is 4 times more expensive than Pentium M 755 (2GHz vs 2.1GHz). The same is for Pentium M 770 vs. 780 (2.13GHz vs 2.26GHz). For my T40 project, I cur...
