  • 1. Curved Keyboards/Acer
    I use an ergonomic keyboard on my desktop. Due to my bilateral carpal tunnel (still got it after 3 operations), I cannot/dare not use a conventional keyboard. I am considering an Acer laptop mostly because it seems to be the only laptop which has a CURVED keyboard. I have whittled the choices down to: Acer Ferrari 3000LMi Acer TravelMate 803LCi Acer TravelMate 804LMi /Centrino P-M Any comments on the above laptops? Do you know of any other brand with curved/ergonomic keyboards on laptops?
  • 2. Graphics display on Linux-based Thinkpad 760XL: help!
    The system is an IBM Thinkpad 760XL, which apparently has the Trident Cyber9358 chip in it (which lies and says it is the Trident 9660). I recompiled the Linux 2.4.24 kernel (Linus kernel) and installed it. I put the proper PCMCIA drivers in the kernel - instead of as a module - (and it works like champ!). I also included the Trident driver for the console in the kernel, and it doesn't work right. The display is there, but the graphics display almost as if they are doubled or being seen through in multiple "parts" (overlapping). The text is "doubled" as if it were one of those modems with the echo (unnecessarily) turned on. And this doesn't have anything at all to do with X yet.... I tried adding and subtracting options from the kernel line such as: video=vesa:mtrr:stretch video=trident:xxx:xxxx console=tty0 At this point, if I can't get the Trident to work as a graphic console, I'd just as soon disable the graphics - but neither video= nor console= seems to fix it. How do I get this to work right? And barring that, how do I turn it OFF? And both without having to recompile the kernel.... Thanks in advance!

  • 3. Vaio PCG-SRX51P and XP Pro clean reinstall
    Hello, I have recently done a clean reinstall of WinXP PRO on the aforementioned laptop. I don't have the recovery cd, and have been trying to d/l from the crappy vaio support site all the extra drivers. Problem is I can't get bluetooth to work. The bluetooth device doesn't show up on Hardware Devices as an unknown device even before driver installation. Once I install bluespace, it instructs me to turn bluetooth power on, but the on/off switch only affects the wi/fi card, and the bluetooth device is as if it didn't exist. Could my machine NOT have the device in it? I thought all SRX51Ps have it, and it sure as hell has bluetooth tags all over it. Also tried installing the firmware for Microsoft stack compatibility that appeared a month ago (and the suddenly dissapeared again) from the vaio support site. The installer complained about my machine being incompatible, even though on the web site it claimed to be prepared for this specific model. I guess the question is: Is Sony's bluetooth implementation any good and can it be made to work with a clean installation of XP Pro, or should I just keep on using my D-link dongle and stop complaining? ALSO: Has anybody managed to get the jog dial wheel to work as it should? I install the jog dial driver and everything goes smoothly, I try all possible settings, and the darned thing still won't scroll my web pages. Thanks in advance for any help, Ilias

Sony PCG-FX140, PCG-FX250, and PCG-FX340 problems ...

Postby eternalrecycler » Sat, 10 Jul 2004 14:43:09 GMT

This is the first time I've posted for all three ailing laptops at
once. I've taken the opportunity to do certain things because I have
at least two laptops for parts swapping.

PCG-FX140:
No response from the AC adapter (confirmed to be functional). Powered
from the battery, the bezel lights blink in alternation from the power
and battery lights at once, to the "lock" lights (Caps, Num, and
Scroll) at once. It keeps it up until I release the power button.  I
changed the LCD harness (part number's the same for both harnesses),
but I didn't regressive test the laptop before exchanging.

PCG-FX250(K actually, but that doesn't matter here):
Water damage special with absoultely no response, despite changing
power sources (AC adapter and battery) and swapping CPUs, too from the
FX340. Supposedly water seeped into the PC card slots. I'm really
really really hoping it's just the power supply, but I don't know how
to swap 'em.

PCG-FX340:
The power lights come on, but there's no response afterwards. I tried
reseating the CPU and using the FX250's CPU. Same response.

I've tried with the battery in both bays, too.

Anything else I can try, given these three laptops?

Thanks for reading!

1.Sony Vaio PCG-FX250 Laptop ME to XP modem driver problem

Hi,
I am hoping someone can help me. Since I am poor I must run constantly
behind technology. My current hand-me-down is a Sony Vaio PCG-FX250
Laptop that came bundled with Windows ME. I am living in Italy and took
it to a Computer Shop to have them put Windows XP Pro on it. What
happened was the driver for the built-in  Coneexant-Ambit SoftK56 ICH
modem would no longer function. We went to the Sony website to down
load the driver, but it was labeled wrong and what we got was a sound
driver in disguise. I am surprised at how hard Sony is to get a hold of
as far as tech support goes. I am disappointed in the level of service
they provide.


The technician had a heck of a time finding any driver that would work,
and in the end found a generic driver that functions, but not as well
as  it did with the original Windows ME driver. I have been looking for
answers but most of the strings are 4 year old by now. As I say I am
coming late to the party.  I am wondering if anyone has found a more
current solution to this annoying driver problem?  Thank you. Any help
would be appreciated. D. S.
