Trying to get more life from my laptop.

post #1 of 5
Thread Starter 
I was just looking around on the net and just thought to look up a review of my laptop. I found a CNET.COM review of my laptop which is a ThinkPad R51 with some upgrades (RAM, CPU, ECT) and it showed a test of the battery life. A test in which they got just over 4 hours.

I thought that was nice and then looked up my sister’s laptop, which is rated at 5.8 hours. It’s a ThinkPad Z60m.

So that got me to thinking. What if I disable some hardware in my device manager?

Do you guys think that disabling some of the unused hardware will get me a bit more battery life? I have disabled things like the IR port, 56K modem, Ethernet controller (I use a wireless PCMCIA card for internet), COM1 Port, and the old school printer port.

I will be running some of my own test but they will take some time to do. I just wanted to hear what you guys have to say and weather or not its worth doing the tests at all.

Thanks for posting.

I personaly think no this isn't worth it... You may get some more time but not enough. How old is the laptop? When they tested it, it was a brand new one and I've always found that batteries lose their recharge capacity for time...

Things you can is when you go into power from the battery set your vid. card to darken the screen... I find this steals the most juice.

Yes I know that, The laptop it's self (the one I own)is a year and a half old a bud of mine bought it brand new at a local store. The R50,51,52 series came about some time in 2003.

I think I will just run some tests once my battery is done charging. that is quit a bit I hardware that is disabled. all I need to do is test for a base line first and then disable then and retest.

A while ago somebody recommended undervolting (using software) your CPU. This wouldn't render your laptop unusable if you went too low, since it's done in software.

You could manually enable it till you found the sweet spot, and create a backup user that won't load the software when it starts up in case it's too low.

What software should I use for under volting? CPU-Z doesn't read my core voltage so I don't know what it is.

Also is there any software that I could use to overclock it? I have tried clockgen but all the PLL when loaded just do nothing or lock up my laptop and it has to be rebooted.

It has a Intel 855GME chipset, the one that supports 333Mhz RAM not the other one that only supports 266Mhz.
