Solved My HP Laptop seems hot after downloading windows 10

Specs: Windows 10
My HP Laptop seems hot on the opposite side of the power cord after downloading windows 10.

Has anyone had any luck using a cooling pad. I already used compressed air, which did not help.

"after downloading windows 10"
Do you mean immediately after downloading Win 10? If so that might be noticeable as it is a big download and install.

When you say "opposite side" do you mean the adapter itself, the domestic power side, or something else?

✔ Best Answer
Might be useful to check/verify that all cooling vents are clear; and also that the fan is running and no accumulated dust on it?

I find having a laptop raised an little from the desk etc. is usually adequate to ensure decent airflow around the case. Raise the laptop with a couple pieces of wood - one on each side; what used to called 2x1 in the days of the "raj", and the "empire"; nowadays (in the UK - thanks to interference from across the North Sea) it's usually referred to as 50x25mm.

Equally a couple of short lengths of compressed foam strip/packing will do the job (not polystyrene/styrofoam as it tends to weep/shed bits of itself over time; and is pain to clear up).

I mean the power cord

Thanks I will try raising the laptop. I already used compressed air to clear all vents

Do you mean the actual cord, ie the cable itself, is getting hot? It would take one heck of a power load for that to happen so it seems quite odd to me.

We need all our questions properly answered so that we can give you the appropriate help.

The mains side power cord; rather than the low voltage one that goes to the laptop input jack?

If so, try another power cord... The mains cord could be failing... (insulation). The adapter itself. "could" be starting to fail - internal shorts/leakage etc.... and drawing more current on the input side that it ought...and thus starting to get "a little warm".

Most of the mains cords are pretty standard figure of eight into the charger/adapter module; some a three leaf clover style. Whichever one it is, any compatible cord will do for a test.

Incidentally how is it (how warm...?) at the main's plug end; and possibly along the cord between the mains plug and adapter connector?

The only thing I can imagine that would remotely cause a power cord to become hot is a poor connection at one end or the other. Even then the heat would be concentrated at that one end only. The chances of modern plastic insulation breaking down sufficiently to cause the cable to get warm are very remote indeed. More serious symptoms would come along if this were to be the case, because the power drawn to produce noticeable cord heat would be something akin to that of a large heater.

The adapter itself could overheat due to a fault but this would need to be very hot indeed for it to draw enough power to warm the cord (cable), as given in my paragraph above.

Now for a few guesses. Maybe it just "seems" hot for some reason or another. There are many things that can affect this judgement, such as how warm the room is or how hot the hands happen to be. Otherwise, good idea to check the vents - maybe the computer is overheating and the heat being discharged from the vents is being directed towards the cord making it feel warm.

Agree that a poor connection at the "hot" end could/would cause the connector at that end to "get a little warm"...

If the cable was starting to fail mechanically at the "hot" end - i.e. the inners were starting to fray/break... then that too could cause "heating up". On many an Apple adapter the cables fail at the laptop end of the cable (the plug that goes into the laptop) - but that doesn't "usually" get overly warm

If it fails in similar matter on the mains side close the mains plug or the adapter end ... then warming effect could/would be likely...

Many mains adapter/charger cables fail very close to the actual plugs on them; rather than somewhere in between. I have had to reject/replace few (cables) in the past for laptops that were (shall we say) subject to heavy (ab)use by the end users in a broadcast studio environment.

That it's the power cord (#3) would likely remove the warming effect from the laptop vents? But it doesn't totally eliminate the charger module being a little upset internally; nor a possible cable failure developing at the charger end; nor a dodgy/loose/intermittent connection there from the main power cord.

A few branded adapters do run "a little warm"; and certainly some of the third-party replacements do. Acer branded usually are OK; but some of the alleged genuine/guaranteed OK for Acer replacements (third-party) do run "warm". Similarly with Dell.

If it was the actual computer end of the cable getting warm... then it might be due to an incorrect size connector; and the difference is sometimes only 0.5mm between the correct one and one that "allegedly" fits... A family member had one such situation a while back with an alleged Acer compatible adapter. When he replaced the alleged "compatible" module with another (badged by Acer in this case) all was well; things no longer seemed a "a little warm there" - and the plug fit was also more positive...

The power cord is not hot. What is hot is the computer itself, on the opposite side of the power cord.

Ahhh... Muchos konphusions...

How long did it take to downloa win-10, and how humungously large was the download?

Re #10
I guess one tiny word threw us a bit, opposite side "of", as compared to opposite side "to". OK then check the vents as given, especially if it was just temporarily hot immediately after the Win 10 install (my first question in #1).

Now Windows 10 has been downloaded it should not really run noticeably more hot than it ever did, unless there is some high activity now going on. Task Manager > Processes might reveal something:

It's amazing how the vents get clogged on so many laptops at the same exact time they get windows 10!!

A major upgrade such as Windows 10 can cause various issues, which is why I haven't gone for it yet because it will obviously have the usual teething troubles. However, I have not seen overheating reported anywhere else, have you? Overheating can come to a head any old time as dust builds up.

Derkek:

Thanks for all your help. I have purchasing a cooling pad, from amazon, and it seems to have helped. This also raises the computer, as some have suggested doing.

If your computer has inbuilt sensors this freebie should be able to give you the temperature readings (with and without the pad):

re' #12...It's a built-in special effect for win-10; and clearly very effective...
