JULY

This thread contains a summary of all generic, unsolved problems of the Studio 1747 laptop - excepting the following:

- for throttling issues of the Core i7 processor, open this thread:
Throttling of core i7 processor in Studio 1747

- if you have any video problems, please hit this thread:
Studio & XPS users experiencing video lockups/freezes/throttling

- if you look for infos about a 130 watt replacement A/C adapter:
Attention Studio XPS 1645/47 and Studio 1747 owners

for all other, generic problems, please use this thread! I´m sorry, it wasn´t my idea to split the 1747-problems triple - I was told, the originally thread becomes to big and confusing. So let´s try out if this splitted threads are a better solution! Smiley Surprised/ However, here is our well-known issue-list again, simplified from any throttling- or video problems. Let´s discuss and talk about these known, and also upcoming, unknown issues of the Studio 1747 within this thread.

still unsolved Studio 1747 issues - Bios A07 - JULY 2010

►Performance between battery and AC power
most Studios runs with a bit more performance if only battery is connected

►Problems resuming from sleep and/or hibernate
if the 1747 "sleeps" more than 30-60 minutes it´s possible that it don´t resume anymore but turn it off&on "hard" by holding power-button

►Permanent running fan

fan starts causeless running at increased speed shortly after turning the 1747 on. Fan keeps blowing at increased speed, even if Windows boots all over and CPU idles - because of the still-blowing fan only at ~32° C. You can stop the fan only with a reboot or by stressing CPU - if temperature reaches 48°+C, fan slows down to lowest level. Turn off stress test, temperature drops below 48°C, fan turns off then. Confirmed by several users.
new BIOS A10 seems to solve this, but not 100%.

►Too less temperature range for fan
fan needs an extended temperature range in office mode. At the moment fan turns on at ~53°C and off at ~48°C. That causes the fan to start&stop every 10-15 seconds, very bothering

►Cutted sound
If the IDT sound "idles" for a while and you play then any sound, the first ~0.5 seconds are cutted! This happens only one time, following sounds are played correctly! If you stop and wait a few minutes, the next sound after this idle time is cutted again

►Not enough power to USB ports and Firewire
There are pages upon pages of various users all experiencing the same issues.

Re: Studio 1747 - generic unsolved issues - March 2010

Thanks for starting this AX-Turbo.

Just like the other 1747 threads I'm going to be trying to keep the discussions on topic as much as possible.  So please be warned that posts that stray too far off topic will be deleted.   I want to try to keep these threads as useful to as many people as possible.

I do have noises and crackling when turning from the 90 watt adapter to the 130 watt adapter. After getting this video from me support won´t reply anymore...

thats curious! It seems, every time one problem is gone, the next one comes up at Studio 1747! I use the "brick" 130 watt adapter, no crackling here.

I am really confused of splitting the main thread into 5 others. But if it helps...

It seems that the only problem i have now apart from the throttling is the sound being clipped, any word on that?

Cheers

I agree with you, but I didn't think that this helps. My "favorit" folder in my browser about the 1747 is really full...

Everything was perfect organized by AX-Turbo in the old thread....

130 watt adapter noise issue

I watched your video and can't figure out what you're trying to show. It probably doesn't help that you have background music playing. When are we supposed to hear crackling noises?

Re: Studio 1747 - generic unsolved issues - March 2010

Hey dcraigw,

are you really want to say you are not hearing the difference between the first adapter (90 watts) plugged in (yes there is background music, but nobody else was wondering about this till now...) and the second adapter (130 watt) even when I plug it in and out at the end of the video? You must be kidding me. Btw. the support admitted there is a problem when seeing this video. As you might have read, I got a second 130 watt adapter, getting the same noises. Now their plan is to change the mainboard.

Thx for your reply.

cheers

Christian

edit: the spectrum of the noises is bigger than the noises you hear, when the second (130 watt) adapter got plugged in. But my camera is not able to record this better.

Where is the sound coming from? The power adapter itself? The laptop speakers below the keyboard? The "subwoofer" on the bottom of the laptop? Somewhere else?
