Dell Inspiron 14 7447: Automatic shut down every 30 min exactly DELL inspiron 14 7474

Hello,

My laptop DELL inspiron 14 7470 shuts down every 30 minutes exactly. I have already tried to repair it a another company but they said they need to replace the motherboard but couldn't find the spare parts in Singapore. This is the message they wrote:

"PCB related problem. Was previously replaced 1/0 chip bust still same issue. Possible internal PCB layer. Through hole connection adapter sets hot then PCD has result Thermal expansion that results to lose contact on internal layers"

After that I made a troubleshoort with DELL and they said the motherboard needs to be replaced but it is out of stock in Singapore and needs 6 weeks for delivery.

So my question is could it be software problem that I could repair myself?

Thank you for your assistance.

Dell Inspiron 14 7447: Built in speaker issue

Hi,

I formatted this laptop to factory settings and still the speaker is not functioning well. It has low volume and a choppy sound. Is the speaker damage? Where can I buy parts?

Thank you.
