Running hot and shutting down randomly

by chf_2258 / May 6, 2010 11:43 AM PDT

HP G60-440US WIN7 Home 3GB RAM

I use MSE for security and Chrome

My Laptop has now shut down when on battery power 2x and then it will not start unless I disconnect & reconnect the battery. I just did this without even plugging it in and the battery still had 20% juice left. In addition, I have noticed it running very hot a few times but that has been, I think, because the CPU is addressing something and operating at 90-100%.

Also, I did a system restore after the first incident 3 days ago and it just happened again.

Any feedback?

Thanks, Chris

Sounds proper.

When the battery is at 20% then all bets are off. Yes I think someone could do a better job of explaining why but I'll just nod and write that I would not expect this to work. Let's see if anyone will write a longer explainer.

At 20% it is time to plug it in.

As to the CPU getting hot when it runs at 90 to 100 per cent, that's normal too. I suggest you find out what the machine is doing as when it is on battery power such high usage can drain the battery faster and cause early shutdowns.

Thanks, and yes, 20% is close to "the edge" but until these two would run to about 12% then give me a warning and then in a couple of minutes it would "sleep" (unless, of course, I plugged it in). Now it is turning off and when I start it, instead of saying "system resume" it says "Windows wasn't shut down properly...etc...etc...". Also, I need to physically remove and re-install the battery for it to start again.

As for the CPU, I mentioned that in case that may have something to do with a battery malfunction. It just seems wicked hot sometimes.

Maybe that will better explain the situation.

I can explain why it used to run down to 12%.

In reply to: Battery

Most laptops sold have pitiful 300 CYCLE BATTERIES. These age fast and as they age you see problems like yours. (Battery only, not the CPU 100%) Let's take their word it's only 300 good cycles. That means in daily use you pay about 30 cents per cycle.

The lesson many learn is to not use the battery unless there is no other choice.

The shut down improperly is the right message under these conditions.

Back to the CPU use. Given no more details such as what's running I suggest you post a HIJACKTHIS log at bleeping computer. Where is that? Read;forum-threads

As to hot. Today's laptops are mostly desktops in laptop form and not literally to be used on our laps!

Battery life
by chf_2258 / May 7, 2010 2:08 AM PDT

Thanks - that makes sense. I bought this bad boy last August but that battery has used a LOT of cycles. In the past, I think I just got lucky with other battery's i.e. kept them plugged in more often than not.

Thanks again, Chris

Batt. Life/Hot CPU
by wyrmzr / May 7, 2010 10:39 AM PDT
In reply to: Battery life

Laptops running warm tends to be fairly typical after just so long; they often build up dust that covers the vents, often this accumulation looks more like dryer lint than anything else. Naturally, that won't go through the fins on the heatsink, and it can cause the system to overheat if left unchecked.
You may be able to clear out quite a bit of dust from the system with some compressed air, but if you've had the system a while, and/or you've got pets, a dusty house, a work area that has who knows what in the air, then your best bet may be to remove the heatsink to clear out the dust that's jammed in it. Not always easy, but can save the system.
Assuming the system only shuts down like that when it's on battery power, and doesn't exhibit this behavior on A/C power, then the two issues are most likely not linked. However, if the system shuts down whether on battery or not, then the system could be shutting down due to an overheat issue. The fix for that is the same thing; try and clean out the vents/ducts on the system as well as possible.

Laptop running hot

In reply to: Batt. Life/Hot CPU

In my experience, my laptop runs hot if it is placed on a cushion-type surface. This blocks the air vents under the machine. If I use the laptop on a cooling fan device, it never gets overheated. I now use a SwissGear cooling fan under my laptop and everything runs great!

That is very helpful and a) I will clean it out and b) the heat is happening, I think, when it is on my lap, bed, that makes sense.

Thanks again, Chris

I cut a piece of 1/4" pegboard slightly larger than the laptop and set the laptop on it all the time. If I lay it on the bed or carpet I'm safe. On my lap it's even better because most of the holes are open, and it insulates my lap from the heat also. And it's cheap

Laptop overheating regularly
by MarkinTO / May 7, 2010 1:39 PM PDT

HP & Compaq's regularly overheat. The problem can lie in the design of the air-flow in the particular machine. DO NOT try to blow dust/lint/etc through these pathways, rather try to vacumme it out of both the intake and exhaust vents.

Many laptops have a "Pathway" designed into them for air flow to cool the CPU, Video Processor and power-regulators. This can become full of lint/etc, as well as regulators becoming covered in lint/debris.

Further, many had insufficiant or improperly applied thermal heat-sink compounds applied on both CPU/Video chips during manufacture.

This leads to pre-mature shut-down and the death of many hard-drives and supporting electronics. In which case, you need a tech to properly clean out the paths and clean and replace the thermal compounds. In most cases, this will result in a better operating laptop, than even when you bought it!

Don't attempt to disassemble your own laptop, if your not fully aware of how these jig-saw puzzles are put together. Typically, every single part, in some way supports another, so a simple mistake can kill off your machine.

Using a compressed air-can (most have other chemicals in them too) will only force more crap into the worst possible spot!

Latop overheat
by Gallowaylady / May 7, 2010 6:55 PM PDT

Hi. I picked this thread up from my emails. My admittedly elderly laptop (6 years) gets very hot and after reading this I picked it up and looked underneath (probably for the first time in years) and went EEEEWWWW! at the dust in the vents. Thanks for this - I shall give it a hoover and hope things improve. I also get a very slow running response but I do know my battery is coming to the end of its life. I must say I think that 6 years is a good length of life for it. I have a Dell Inspiron 6000.

Running hot and shutting down randomly
by Planet Benner / May 7, 2010 8:03 PM PDT

I have a Compaq laptop and a while back there was a battery recall by HP as some were overheating. Might be an idea to go to the website and see if your particular model/type is faulty.

Perhaps your laptop is overheating:You may need to clean all the vents especially the fan vents with an air duster (can of compressed air).It is possible that your fan(s) has failed or is running slow - they might need replacing.Also make sure you operate your laptop on a solid surface so that air can freely circulate under and around it.
