Any T41 battery saving tips?

[electrizer]

Hi guys! This is my first post here so I think it calls for a bit of an intro. My name is Przemek (23), I'm Polish, currently located in London, UK. Like a month ago I've become a happy owner of a T41 machine (1,6 GHz, 40 HDD, 512 RAM, for work purposes). So far - so good, very satisfied!

Actually I have two questions:

1) Can you recommend either any tips for getting the most of my laptop's battery, or, not to be redundant, any sites or even links to threads within this site if this matter's already been raised (and I'm pretty sure it has )

2) Do you know any reliable place/website selling GENUINE IBM batteries (UK, or US that ships to UK)? I need the main one (possibly 6-cell Panasonic 92P1091) and the Ultrabay one (I think the #FRU is 08K8190, if I'm not mistaken).

Thank you very much in advance!

This thread talks all about some application which will help you extend your battery life.

I don't have a source for batteries, but the applications work great.

Welcome to the forum, Przemek!

As for maximizing your battery life, there is another very good thread ★★★★★ discussing this, see GUIDE: How to max out your battery life *56K warning - Pics* which will point you to the "Notebook Hardware Control" (NHC) program, that can be used to keep power consumption down - and therefore battery time long! You may download NHC via the thread NHC 2 is out! and then get the "ACPI"-file as discussed e.g. --> here - and then you're simply in cool business!

Note: By using NHC to "undervolt" the CPU you don't loose anything (except in some cases the high fan noise and any case the "short" battery time!); what you do is adjust your particular, specific/personal CPU the minimum voltage setting which is sufficient for stable performance - in stead of continue using the default and a bit too high CPU voltage that Intel has specified to make sure that all CPU's would run (the thing is simply, as already said, that most CPU's will actually run exactly as well with slightly lower voltages - and that's your job, using NHC, to find out how low you can go!). The same about the GPU clock speed; downclock it and save power.

To find more information about extending battery time on ThinkPad's, I honestly don't believe you need to go elsewhere... because this! is surely the ThinkPad forum Number 1! Rather I suggest you get yourself a bit acquainted with the Search-function available here - and then you can dig up a wealth of useful information yourself!

As for batteries in London... I am sorry, but I don't have a clue (except www.ebay.co.uk). Hopefully some English forum members can help?

Best regards,

Johan
