Hello guys !

I wanted to post here asking for some help, as I really screw myself this week end and end up going through a lot of stress.

My device is a Dell 15 9560, i7 7700HQ, Nvidia 1050, 16GB of ram and Samsung SSD.

I never been able to really enjoy this laptop without headphones before discovering TS. After undervolting it, the laptop became silent and using it... a dream come true ! After two and a half year... i nearly cried that day, of hapiness, rage. everything.

My system was fine for about 5 month and stable with a 0.135mv undervolt on the CPU. Running running cool, fansless etc... Ohh boy i loved it.
After a motherboard replacement that ive tried to refuse by all means, i had to reinstall all my OS and then installed TS. Of course, i did not start with the same undervolt and started with 0.100, then 0.110 and finally 0.120mv undervolt. Everything was stable so i decided to stop.

After the fans still going on sometimes i decided to try to undervolt a bit more. Idiot and unlucly me. Having already a nearly perfect the perfect running machine, i wanted more and scew everything. Tried 0.130v undervolt. The laptop crashed instantly and restarted. Once I entered my password in windows, it the OS would crash and bacl screen. Tried to boot about 10 times. W10 loads, password, load quickly and crash.

I paniqued and decided to restore to system to a previous restore point. Terrible error as i corrupted my OS. I had to reinstall windows, lost all my files and got through the painfull process to make my xps work as expected.

I was planning on not undervolting it again but of course found the same issues as in the past. Worst, i got used to use the device without noise. Using it is impossible and raging... super noisy with no ability to control the fan of course thanks to Dell.

I was wondering if you could help me undervolting my laptop in a safest way, or with better habbits, to not end up again with the same issue as this week end ?
In case windows 10 doesnt load after a undervolt ? What should be done to solve the issue ? Safe Boot ? CMos Reset?

Can someone give me some advices or tips on how to it properly undervolt minimising risk ?

I dont use the laptop for gaming at all, only for work and heavy web browsing.

Ps. Just remembered, and this is INCREDIBLE.
Without undervolt, the battery lasted me a bit less then 4 hours. After undervolt, 9 hours ...
Before I installed TS, the laptop would iddle at 1000Ghz and still consume 15W. Once I activated TS, even before undervolting, the TDP dropped to 1 - 2W instantly. I was amazed.

Take note i dont blame the software at all for my issue, all the contrary, im really a fan of TS and just looking to improve my knowledge, usage of it.
Sorry for my english and thank you all in advance for you time :)
