Costco Dell DC15255 (Inspiron 15 3535?)

[ygohome]

Picked up this laptop from Costco today here in Louisiana.  It's to replace the 2010 M6500 which isn't able to upgrade from win10 to win11.  Dont worry, I'm keeping the M6500 (I've two m6500s actually) and it's running latest release Linux "fedora 43".

 

I think I got a pretty great deal on the Dell from Costco.  It was 200 off of $599 this week, bringing it down to $399 USD plus accidental ins coverage for 3yrs (that added $69 to my total).  I think it's a deal. 

 

16GB DDR4, 512GB NVMe, 15.6" 1080p touchscreen, Ryzen 7 7730u 15w 8 core 2Ghz base clock, 4.5Ghz  boost.  Integrated GPU, but still probably alot better than the quadro fx3800 that was in the m6500.

 

It's awesome.  No thunderbolt, but it has a USB 3.2 type C, HDMI 1.4, two USB A.

 

it's actually for me little sister who has been using the old m6500 for things like quicken and paying bills etc.  she's going to love it i think. 👍🏻

Here's a few photos of the guts.  It's the smallest physical sized SSD I've seen.  It has two memory slots, and only one was populated.    Pretty great machine for the price.

Updated it to win11 25H2 cumulative security updates (ending in .7171).  It came with bitlocker pre-enabled.  I've not used a PC with bitlocker before.  I had to figure out how to find the bitlocker key incase I would need it later.

The only issue, out of the box, was that SLEEP was acting strange.  If it was on battery, and then I put it to sleep, and then connect the AC plug after it's asleep, it would wake up even with lid closed.  I chose to use HIBERNATE instead of SLEEP as a workaround.  I updated BIOS from 1.0.0 to latest 1.3.1 from 09/2025 and that solved the AC Plug causing it to wake.  BIOS settings didn't have anything for power management, such as disable wake on AC plug, or such.  Also updated the SSD firmware, chipset firmware and drivers, radeon drivers, etc.

Works great.  I wonder if I can upgrade this to 32GB or maybe even 64GB.  Dell website and manual says 16GB is max.  But the CPU can handle 64GB I think.  First upgrade will be a larger capacity SSD.

Old sleep (S3 Sleep) has been replaced with a new default of "Modern Standby" (S0 Sleep).  I only use Hibernate on my Dell work laptop, because "Modern Standby" is always monitoring inputs and thus uses lots of power.  Two common problems with "Modern Standby:"

- Command laptop to sleep, then accidentally jiggle a connected mouse, and the computer wakes up again

- Laptop zipped up in backpack, then a wireless mouse or windows update process causes the computer to wake and bake itself with no ventilation

 

"Modern Standby" is definitely a case of new is not always better, new is just new

Hmm, if that's the case with "modern standby', then perhaps my BIOS update didn't really solve the issue like I thought.  I may go back to HIBERNATE again instead of sleep.  Glad you explained it the way you did because i was originally thinking it was a sleep state BIOS bug issue.
