New T43/T43p Bios!

[Scorpiontico]

i was just looking on how to download the complete installer of DLA (latest) and i noticed there is a new T43 BIOS update.

http://www-307.ibm.com/pc/support/site. ... MIGR-59096

from what i understand it doesnt say anything regarding the heat and noisy-fan issues .... still could you guys confirm it?

also, could you guys post me a link to download the latest DLA software version, i can only find the updater package.

thanks.

ps: hope the info helps.

[Scorpiontico]

seems like it doesnt interest anybody...

[Zeitgeist]

Exactly.
no, the fan noise did not change.
DLA: http://www-306.ibm.com/pc/support/site. ... MIGR-40970 You will only find the update software, the original is in the IBMTOOLS folder (I think).

Does anyone think IBM/Lenovo will make a BIOS update for T43(p) that DOES reduce HEAT & NOISE?

[nrj45]

I don't think t43/p have an heat issue (or i'm lucky) but only hdd and fan issues. Even when my t43p was not undervolted, it didn't come over 70°C which is acceptable. The problem is the fan stepping making our t43/p noisy even when cold.

Hi, nrj45,

it didn't come over 70°C

I guess this temperature is at 100% loading? Is your t43 a 14in model or 15in model?
My t43 CPU temperature is about 50~55C at idle and about 90C after 20 minutes 100% loading. Fan is always on and loud.

are you serious about those temps, because wow buddy you better start using centrino hardware control otherwise take advantage of the heat by cooking something on your t43 .

[nrj45]

Nono i'm serious. It's a 14'' (see sig, i put lot of spec. of my t43p).
With an ambiant temp of 22°C it idles at 42° (800MHz, 0.700Vcore + powerplay set to min perf/max battery). When playing CS Source (1.86GHz, 1.164Vcore, powerplay set to max and FireGL overclocked to 480/300 MHz instead of 400/250) the temp goes around 65-68°C.

Summary : the only negative points i find on my t43p is the fan (always fanning, even when temps are low, making the thinkpad blowing quit cold air) and the hdd 2010 error warning i have to escape each time i boot my t43p (i put a toshiba 1032GAX 100gb 5400rpm 16mb cache). But no heat issue at all (Am I lucky ?).

Did you ever do test without the CHC?

I close CHC and run prime95/torture test/small FFT for 20~30 minutes. The CPU temperature rise to 90C while the ambiant temperatuer is below 21C(when I start the computer and hd temperature reported by CHC is 21C). I just want to know only my t43 is hot or most t43 are hot.

Hi, nrj45,

I didn't run a special stress application exept gaming (making the cpu run at 100% load but I don't know if a prime95 load is "heavier"). But I'm pretty sure that even if would to make my t43p the hottest possible, i couldn't make it over 70°-75°C. Even by playing, the fan speed is the same as when idling (only temps are changing).

As I'm writing this, I'm running prime95 (cpu is at 1866MHz, 1.308Vcore not undervolted) and the graphic card is at it's max factory speed (i mean not overclocked), LCD set to max. The room is at 21°C. My t43p is on a table. I don't know what i can enable to make my t43p more hot. The CPU stays at 66°C.
Since i started prime95, i started also mobmeter to see the graphic of temperature. On the graphic i can see the temperature climbing from about 42°C to 66°C. But the temperature climbs slower and slower. I could imagine that after 2 hours of prime95 the temperature should stay at about 68°C - 72°C.

Now Prime95 is on for 15 minutes. I saw the temperature climbing from 42° to 62°C during the first 3 minutes. And from 62° to 65°C during the other 12 minutes. The graphic in mobmeter is almost horizontal now.

I guess you have some hardware problem around your cpu. or is it a 2.13GHz ?

One thing is absolutely sure my CPU will never become hotter than 70°C in these conditions.

After this test, i put again the undervolted values (1866MHz at 1.164Vcore), temperature is staying at 61°C under load (always with torture test, small fft).

thanks, nrj45. It is very helpful. I will call IBM.

That is unusually hot. Sounds like you may have a problem with your machine.

Here is another data point with a couple of runs on my 1.86GHZ T43.
Both runs were without undervolting and running Prime 95 for about an hour:
1. Prime95-Torture Test-Large FFT, 81C with ambient of 75F
2. Prime95-Torture Test-Blend, 83C with ambient of 80F

The Intel data sheet shows 100C as the point where the processor starts to throttle back to prevent over-temperature. It also has a section on "Catastrophic Thermal Protection" which is initiated at 125C. I think 90C is high but still within maximum limits.

FWIW, the new bios's for all thinkpads are supposed to contain the call home feature from absolute software..

D..d...does that mean that if I update my BIOS, Tania (and her boyfriend Spike) in Vancouver will automatically have access to my hard drive and my data every time I go on line? And wouldn't a BIOS update only place the software on the hard drive, where it would be erased by a wipe or reformat?

[GomJabbar]

And wouldn't a BIOS update only place the software on the hard drive, where it would be erased by a wipe or reformat?

BIOS updates are put in firmware, which has nothing to do with the hard drive. AFAIK, the firmware is usually an EEPROM (electrically erasable programable read only memory) chip. {I hope I got the acronym right.}

[GomJabbar]

Interesting article Bill.

I think that even though they can supposedly wipe the hard drive, that doesn't necessarily mean they can read the information on it. Sending a command such as format C: or fdisk doesn't require reading the files on the hard drive. In fact, some viruses wipe the hard drive, without requiring user intervention.

Even though I said the above, that also doesn't mean that they can't read the hard drive. Encryption may make a difference here.
