The SSD requires more average power than the HDD and all the load is on the 5v supply instead of maybe 50% being on the 12v supply. The doubling of the load on the 5v supply could be a problem in a marginal power supply of a laptop.RAL said:Most 2.5" SATA disks use only the 5V power and don't require 12V at all, even though it is available on the SATA interface.
The power requirements for SSDs has probably dropped in recent years as technology has improved. I checked a few recent drives and the SSDs require a bit less maximum power than hard drives.
An example:
WD 1.0 TB Black Performance HDD
Max power: 5.35W
Average power: 2.0W
Idle power: 0.85W
Samsung QVO 870 1.0TB SSD
Max power: 4.0W
Average power: 2.2W
Idle power: 0.03W
I don't think the load on the 5V supply is increased. Most spinning 2.5" hard disks use 5V only, and not the 12V supply. I can't say that's true for every 2.5" SATA disk ever made, but I just checked some 12 year old Hitachi disks that I have and even those used only 5V and not 12V, and draw 5W max. The use of 12V is more common on 3.5" hard disks because of the larger, heavier platters and the need for a stronger motor. They typically draw 9 to 10W.LarrylLix said:The SSD requires more average power than the HDD and all the load is on the 5v supply instead of maybe 50% being on the 12v supply.

It would be hard to predetermine, as the specs prefer to just give total power capacity, which includes all voltages, and not spec individual output capacities.
If the lack of 12v requirement is true, in this case, you will likely be alright, but your figures state the SSD has a 10% higher average power draw than the mechanical version. Peaks can be just a capacitor handled blip for a few milliseconds and may, or may not be, important.RAL said:I don't think the load on the 5V supply is increased.

So if the 2.5" HDD is about 5W max, and the SSD is only 4W max, everything should be just fine. If the PC or laptop could run the HDD without problem, it should be ok with the SSD.

Amazing. How long ago wat this? I tried multiple times two different phone numbers, even called their sales department with promises, but no follow-up!mikefamig said:BSR
I had just the opposite experience with Lenovo. My wife's laptop keybboard failed. We had bought the machine at Costco and they would not take it back because it was almost a year old and they have a time liit on returns.After contacting Lenovo they sent her a prepaid shipping label and we had the laptop back in under seven days at no cost. I was amazed.

This was a few months ago. She did it all through the internet. After asking a few questions about the problem they gave her a ticket number and a shipping label saying that they would inspect the machine and let up know what they found.. They paid freight in both directions and there was no charge at all for replacing the keyboard.BraveSirRobbin said:Amazing. How long ago wat this?
