    Larry Ng Oct 28, 2021 support, go there ask there, (no model # told at all and 15 is LCD size.
    auto shut downs are mostly overheating, clean it first. all vents, fans and heat sinks, nothing new here all PCs do this lacking service.
    the PC you can put on app called HWinfo32.exe portable, free and safe.
    all PCs do this, after aged.
    first when it gets too hot the CPU slows down (intel. inside, does that in silicon)
    then at about 90c the cpu shuts off, to save its bacon and YOUR WALLET.
    on newer PCs GPU does this too , too hot.
    and newer PC with newer SSD now the SSD can self shut off, all for the same exact reason TOO HOT.
    does it shut off with AC pack connected to AC power? if not the battery huge is bad.
    battery huge can even short and overload the power rails in the PC, even at random. so we remove it. and test the PC. lacking pesky old huge BATTERY MAIN.

    no pc told at all, the service tag on the PC tells full model and product ID full.
    this makes finding the service manual 100x more easy and same for PARTS.

    for sure shut downs have many causes, overheating tops the list.
    NO PC told . 15" laptops lots of models (vast), for just size. 15"

    the big battery inside varies by all versions, from old that just drop off bottom to deep inside
    I test all laptops first with the big battery removed,when bad it can caused the PC power bus inside to overload.
    tested on AC power pack only, no BIG BAT.
    sadly DELL removed the bottom sticker words, of model #

    Dell Inspiron 15 3565 / 3567 ( just one of 100s of models 1 example)

    gone is the model now (newer), it is now a secret ( why body knows)
    but the tag there shows the service tag.#
    and at you tell them there in the tag box online the tag number and that then tells you real model you have. vast exit word wide.
    that is the new dell way of doing business, now. no model # on it.

    then go here

    tell them the service tag number
    then it tells you what you have.
    for parts or service or software, it must be known this fact.

    if still fails to run right, then run free overheating, software, 50c is normal 80c it slows down and 90c stalls. dead.

    loss of power
    or overheats
    and 20 other reasons./ (bad parts inside count them any can fail)

    lets say the AC pack is bad or intermittant or its cables or jack bad (cracked?)
    then the battery goes dead. and PC goes dead.
    see? it has 2 power sources,. if both fail so does the PC.

Blow into the fans. It could be shutting down due to the dust building up inside of the fans, which can cause overheating. Let me know if that works!

My Dell Inspiron 15R fan is not working....the laptop gets overheated due to this & shuts down after 15-20 minutes.The laptop has exceeded its warranty period.I had bought the laptop in May 2010.

When the CPU overheats then it will shutdown (i.e. thermal overload) and won't boot up again until it has cooled down.If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes this problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged withdust the remove the dust and make sure the vents are clear and dust free. Use acan of compressed air to do this.

Please try to upgrade the BIOS version and flash the BIOS. Please check the link and follow the instructions:

Overheats and shuts down after about 20 minutes

Usually when a CPU overheats it shuts down and after it cools down you can re-boot it again.
Continual overheating will eventually cause the CPU to fail.

The overheating is usually caused by blocked vents and or dust build up on the heatsink and/or fan. Remove this dust from the heatsink and fan and this should fix your overheating problem, unless you have a faulty fan, in this case you will need to replace the fan.

Dell inspiron b130 won't boot up.

Connect an external monitor to the laptop and see if you can see what is happening on that.
It is a possibility that your inverter is faulty and will need to be replaced. They will normally power on for a few seconds, then cut out.
Remember to set the laptop to use the external monitor with the function keys.
