Solid-State Drives (SSD)

[Jumme]

(Please excuse me as english is not my first language)

Installed a brand new Crucial M225 128GB SSD drive. Laptop is a brand new Lenovo X200 7457, T8600 C2D 2.4Ghz, 3GB RAM, with the Lenovo 6 Cell battery pack.

"The ThinkPad X200 Series 6 Cell Li-Ion Battery (43R9254) features:

• Lithium-Ion (Li-Ion) technology
• Six-cell, rechargeable system battery
• Output Voltage: 10.8 V dc
• Battery Performance amp-hours: 5.2 Ah
• Battery Performance Watt-Hour: 56.2 Wh
• Meets standard system battery specifications
• Over-discharge protection"

Crucial convinced me to buy their SSD drive with the following statements:

Increased power efficiency - Ever have your notebook battery die during a presentation? With no moving parts, SSDs require less power, improving battery operating time in notebook PC's and portable electronic devices.

So... prior to installing the Crucial SSD drive, I had myself approximately 5 hours of battery time. Going to power saving mode, which I primarily use (low screen backlite, doesn't bother me), I could easily reach almost 8 hours of battery life.

Installed the Crucial, fresh install of Windows 7 RTM and all Lenovo system drivers (power mgnt, etc).

So what now? I've got a measly 4 hours of battery, compared to the 5 hours before?

And going to power saving mode, its completely crazy: Before, I'd get almost 8 hours batterylife... now I get 4:25 hours?!!

That's a 45% reduction... That's just unacceptable?!

Or did I install the crucial wrong? Do it need some kind of special drivers, or what?

Please help me.

What you are experiencing is not what we would expect… we are in the process of testing this in our lab to see if we can duplicate the issue. We will post back when we have more information on this.

Thank you very much.

I myself is about to change back to the old harddrive, to see if I can dublicate the issue, as I did not test battery time but stated calculated numbers from Lenovo power mngment.

If it is of any concern, the old harddrive was "Lenovo P/N 42T1103, Hitachi P/N: 0A57305".

Crucial firmware is 1571.

Hi everyone,

I too am experiencing extremely poor battery life but with the 256 GB model of the SSD drive.  I'm running both windows 7 and Mac OSX (via bootcamp) on a brand new mac book pro with the latest firmware 1819 on the hard drive.  I went from having several hours of battery life to under an hour.  I travel so my purpose for forking out the $800 for this drive was to reduce battery consumption and improve battery life.  What I've seen is the total opposite.

I need someone to explain this phenomena to me.

Thanks in advance.
