Keeping Laptop running for long times

Hi,

I have bought my first laptop (HP DV 6701 AU) about 3 weeks back.

Right now am running it on AC power directly with battery removed, I have also bought an USB cooling pad (basically a stand with 3 fans underneath it).

I have 256 Kbps unlimited conn from IOL. So my laptop is on about 18 hours a day daily.

One of my friends told me that keeping laptop running for extended periods of time would harm the laptop (speakers would go bad after some time, processor might be effected etc)

I would like inputs from the members here about this.

just like a desktop, so no

in fact laptops and desktops actually its better to keep it running, imagine starting your car over and over and over and over and over youre losing power and breaking the battery down much faster than say a 1200 mile road trip with no stops

as long as its with in running temp, it will be fine for the next years to come


and im speaking from experince, never once have i shut any of my 7 laptops down aside from restarts for programs/updates

Thanks for the reply.

What is the ideal/preferable running temp for a laptop?

And are your laptops working fine? I mean no problem at all in the speakers or anything else?

I anyway have taken my battery out so won't worry about breaking the battery.

depends on the laptop, most will say what proper running temp is

and, back in the past i used to play music to help me fall asleep, so i had music on 24/7 never a glitch, at all

now i dont do that cause i listen to music that is ment to amp you up and does just that to me

but nothing will happen to the speakers........

if youre afraid of that, do what i did, get usb powered speakers tad louder than most laptop stock speakers, and run off usb for power

The only downside to running your laptop on AC power (without a UPS or battery backup system) without the battery is that if there's a power failure, the system will shut off with the power, whereas with the battery, it will stay on, which is one of the benefits of having a laptop.

As for temperature, it does depend on the particular laptop. Typically, I think in the 40's C is fine for idling. My M90 (CPU temp) sits around the low 40's with the fans on, and my 700m sits at the low 50's, both on pretty much 24/7, except when I need to move them. The fans are pretty much programmed to keep it within acceptable ranges, so you should be perfectly fine.

Keep an eye on temperature. If it's going to stay at the same place for a long time, it may be a good idea to keep a cooler under it...

Other that, what I also DO suggest is to NOT take the battery out (unless you want an UPS, which is the same of having a battery, only with more trouble). C'mon, what is that bad about replacing the battery? After all, it is going to fail no matter you use it or not, and plugged in, you don't have to worry much about energy black-outs (spikes are another thing). Me, I don't think taking the battery out is worth anything. And Lithium batteries don't suffer of overcharging problems.

Thanks, for the reply guys.

DDDa I have a USB fan underneat, The temp as shown by speedfan sowftware usually is between 45 to 52 C.

I think I agree with you about keeping the battery out, but one thing which still convinces me to keep the battery out is that when the battery is in the laptop gets more hot, right?

program monitors for heat, dont work that well

speedfan told me my old desktop (with the best cooler on the proc) it was running at 700rpm, and clocked the temp at 170F

id say all laptops and desktops have a fail safe shut off, if youre carefull it wont over heat and youll be fine

When I first got my laptop, I babied it by taking the battery out and leaving it on for extended periods of time. Then, I realized it is just a computer and started leaving the battery in all the time and turning it on/off when needed. Since then, I have encountered zero problems. I turn the computer off when I am done with it, and turn it on when I need it, regardless if it is one minute from turning it off to a day. I haven't seen any problem. I guess I just really trust my laptop to start up when I tell it to.

I have noticed no visible wear or anything. My battery still holds an excellent charge. My speaker is fine EXCEPT I think I hurt it by playing around with different types of frequencies at high level volumes so I do NOT recommend you doing that. I think the speaker is "healing" itself, but well, that is how I would put it because it's condition has gotten better. i

your friend is full of it...

simply put there is a higher potential for something to go wrong if you are the victim of a design flaw or that kind of thing but it wont kill your machine. the thing it is worst for is your battery but with that removed you have not got issues.

Really? I never noticed that (when I got the notebook, I too removed on the first days when on AC... too much care), but I never used a temp. probe to be sure, but even that tells me that the difference, if any, was negligible. Once again, IMO, the pros overcome the cons.

removing the battery from the laptop might let air reach deeper into the chassis but the battery itself should not be heating up very much. it's a matter of insulation.

however, if the heat from the laptop is heating up your battery, then that will shorten its life significantly over long periods of time. in that case, you can prolong your battery life by taking it out when plugged in at home. a well designed chassis will not pass on heat to the battery.
