Why it exists

Renting laptops has one problem renting machinery does not

A laptop is small, valuable and easy to disappear with. Once it leaves your counter, the only leverage most rental businesses have is a phone call.

  • The laptop is out and the invoice is not paid

    Chasing a lessee who has stopped answering means a field visit, a legal notice, or writing the machine off. None of those are cheap, and none are fast.

  • No idea which machines are still alive

    Your system says forty laptops are on rent. It cannot tell you which are switched on, which have gone quiet for a fortnight, and which walked off six weeks ago.

  • The machine comes back lighter than it left

    A 16GB unit returns with 8GB and a smaller SSD. Without a hardware baseline and photos from handover, it is your word against theirs months later.

The lock agent

One switch per laptop, and a lock that holds offline

The agent is a small Windows service, macOS daemon or Linux service installed once on each machine. It keeps a live connection to Rentablez, so an admin can lock or unlock any unit from the order or the stock record and an online machine responds within seconds. A locked laptop stays locked offline and across restarts, and a one-time code can release it when it truly cannot get online.

  • Lock and unlock restricted to admins, with a pending state until the laptop confirms
  • Full-screen lock the lessee cannot click past, showing your own message
  • Hardened service with a watchdog task, so it is hard to remove
  • Uninstall from the laptop only after you approve it in the Guard app

Location

Know which city every rented laptop is in

Every time a laptop checks in, Rentablez places it on a map from the internet connection it is using: city-level, roughly within 10 km, with no extra install and no prompt for the customer. When a rental stops answering, you know where to start looking, and the 90-day trail shows where the machine has been.

  • Latest location on the order, the stock record and the status board
  • Map with an accuracy circle and the trail of earlier check-ins
  • History over the last 7, 30 or 90 days
  • Precise Wi-Fi and GPS location with Locate now, when the customer allows it

Beta Ubuntu 22.04+ · Debian 12+

Linux

Linux laptops and servers, on the same board

Ubuntu and Debian machines appear in the same Guard screens as your Windows laptops and Macs. Install the .deb with the setup app on a desktop, or with one command over SSH on a server with no screen.

  • A lock that takes over the screen

    A locked machine switches to the Rentablez lock screen and stays there: switching screens, logging out and restarting all land back on the lock. Unlock returns the customer to their desktop with their apps still open.

  • Locking a server cuts its network

    Set a machine up as a server and Lock also blocks every connection except its link to Rentablez, so its websites, SSH and databases stop answering. Unlock brings them back within seconds. Nothing is stopped or deleted.

  • Health monitor

    Every 5 minutes: free disk space, memory, temperature, load and failed system services, shown as Healthy, Warning or Critical with a 30-day history and an alert when a reading turns critical. It watches; it never fixes.

The whole Linux agent is in Beta: try it on one or two machines first. Give customers an account without sudo and set a GRUB password, because an account that can use sudo can remove the agent.

Beta Windows · Lenovo ThinkPad only

BIOS anti-theft

Make an opened ThinkPad refuse to start

Switch on the ThinkPad's BIOS supervisor password and Bottom Cover Tamper Detection once, in BIOS Setup. Guard checks that both are on, tells you which step is missing before the laptop leaves your premises, and keeps the password encrypted in Rentablez so only an admin can reveal it.

What happens if someone opens it

  1. 01

    Someone unscrews the bottom cover to take out the RAM or the SSD.

  2. 02

    The ThinkPad records that the cover was opened.

  3. 03

    At the next power-on it stops before Windows loads and asks for your BIOS password.

A new drive does not help them. The password lives on the motherboard, not the disk, so the laptop still asks for it and still will not start.

What someone does Guard alone With BIOS settings on
Opens the cover to take the RAM or SSD Swap alert on the next scan Will not start without your password
Fits a blank drive to wipe Guard Guard is gone with the old drive Still asks for the password

Guard never writes to the BIOS or sets the password for you. It only checks and reports. Keep the supervisor password safe: if it is lost, a locked ThinkPad may need a paid motherboard replacement from Lenovo.

Beta Windows · ThinkPad and Dell Latitude

OS format protection

Stop a rented laptop being wiped clean

The agent switches off Reset this PC at install and turns it off again within a day if anyone re-enables it. Every day it also checks the BIOS settings you set yourself, and shows each laptop as Protected, Partially protected or Unprotected, with an alert if a Protected laptop drops out.

What someone tries With format protection on
Settings → Reset this PC, or Shift + Restart → Reset Not available: Windows Recovery is switched off
Boots a USB installer Blocked by your BIOS settings
Changes the BIOS settings back Needs your BIOS password; the daily check reports any change
Runs a Windows installer from inside Windows as an administrator Not blocked: give customers a standard account

You set the BIOS password, USB boot off, the F12 boot menu off and Secure Boot on in BIOS Setup; Guard only reads and reports them. Not available on Macs.

Inspections

Build the checklist once, then photograph and film every handover

Template-driven inspections run at dispatch and again at return, on the phone, with photo and video capture built into the checklist. Part of the Rentablez rental plans from Growth — not part of Guard pricing — and shown here because both run against the same asset record.

What comes back wrong

Six things that turn a rental into a write-off

Every one of these is recoverable if you can prove what went out and reach the machine while it is still out.

  • Cracked screen

    Major

    The most common return defect and the most expensive. Photographed at dispatch, it stops being a debate.

  • RAM or SSD swapped

    Critical

    A 16GB machine returns at 8GB. Guard catches it on the next boot, not at the return counter.

  • Missing charger or keycaps

    Minor

    Small, constant, and normally written off because nobody logged what went out with the unit.

  • Liquid damage

    Critical

    Often invisible until the machine is opened. A return checklist with photos and video gives you the timeline.

  • Dented lid and loose hinges

    Minor

    Cosmetic until it is not. Grading condition each cycle is what keeps resale value predictable.

  • Never came back at all

    Critical

    The rental ended weeks ago and the phone goes unanswered. This is what the lock is for.

How it runs

Four steps, once per laptop

  1. 01

    Install the agent

    Run the setup app on the laptop and paste its activation code, or click Continue without activation code. Setting up a whole batch? Install them all first and pair them later.

  2. 02

    Bind it to an asset

    With a code, the laptop links to its unit as it installs. Without one, it shows a short pairing code: type it into Pair laptops in the Guard app and map it to an asset tag. Either way one licence binds to that one asset, and protection starts within a minute.

  3. 03

    Keep the switch

    Watch check-ins, get an email or WhatsApp alert when hardware is swapped or a laptop goes quiet, and lock or unlock the machine whenever you need to.

  4. 04

    Release the licence

    When the asset leaves the fleet, click Uninstall and the agent removes itself. An uninstall started on the laptop waits for your approval. Either way the licence returns to your pool the same day.

Two minutes: generate an activation code in the Guard app, choose the protections, install on the laptop.
Licence-based

One licence per asset. That is the whole model.

Rentablez Guard™ is licensed by asset, not by user, not by branch and not by how much you rent it for. Every laptop you want tracked and lockable holds one licence for as long as the agent is on it.

  • One licence, one asset

    A licence is bound to a single laptop. It is not a floating seat and it is not shared between machines — the asset holds it for as long as the agent is installed.

  • Bought in blocks of 100

    Licences come in blocks of 100. One block is the entry point and covers most fleets outright; add another only when the inventory grows past it. You never pay per user and never per branch.

  • Release and reuse

    Uninstall the agent when an asset leaves the fleet and its licence returns to your pool the same day, ready for the next machine. Nothing is stranded.

Guard pricing

Two options, and both of them include everything

Licences are what you buy — one per asset, in blocks of 100. The free tier is not a feature-limited trial; it is the whole product on five licences. Billed separately from your rental plan.

What Guard does not do

Rentablez Guard™

Guard is asset tracking and a lock, not surveillance. It does not read documents, capture the screen, log keystrokes or track browsing, and it does not report what the machine is used for. It reports the hardware, when the device last checked in, the approximate city it is connecting from (or, only if you install with Precise location and the customer allows it, its street-level position), whether it is locked, and on Linux the machine's own health readings. Locking a customer's machine must also be covered by your rental agreement — a contract question, not a software one, and our contracts module can carry the clause.

How we process device and location data on your behalf is set out in the Rentablez Guard Data Processing Agreement. The service is governed by the Rentablez Guard Terms and Conditions and the Rentablez Guard Privacy Policy.

FAQ

Guard questions

What laptop rental businesses ask before rolling it out.

Something else? or email sales@rentablez.com.

How fast does a lock actually reach the laptop?

Within a few seconds when the laptop is online. The agent keeps a live connection to Rentablez, so a lock or unlock is sent to it straight away, on Windows and Mac alike. A laptop that is switched off, asleep or without internet gets it as soon as it reconnects. Until the laptop confirms, the board shows the unit as lock pending rather than locked, so you are never told a machine is locked when it has not answered yet.

Can the customer just uninstall it?

Not easily. Opening the setup app on a protected laptop only offers Request uninstall: you get a pop-up and a browser notification in the Guard app, and the agent is removed only if you approve. On Windows the agent runs as a service hardened so stop and delete requests are refused, with a watchdog that restores it. On a Mac and on Linux it runs as a system service a standard account cannot switch off, though on Linux an account that can use sudo can remove it (you get an alert). A determined administrator with enough time can still interfere with software on a machine they physically hold, so give customers a standard account and treat Guard as a strong deterrent and an evidence trail rather than an absolute. The right to lock the device must also be written into your rental agreement.

What happens if the laptop has no internet?

A locked laptop stays locked, because its last instruction is stored on the device. Restarting it or pulling the network cable does not unlock it. A laptop that is offline when you click Lock gets the lock as soon as it reconnects. Being offline does not lock a laptop by itself. If a locked laptop really cannot get online, you can issue a one-time code that unlocks it for 1, 3 or 7 days. The next time it connects, it follows Rentablez again.

Can I change what the lock screen says?

Yes. Set your own heading, message and contact details once in Settings, and every locked laptop shows them, Windows and Mac. Change the wording while a laptop is already locked and the screen updates within seconds. If you set nothing, the laptop shows a standard message asking the customer to contact the rental provider.

Can Guard stop a thief from swapping the drive?

On business Lenovo ThinkPads, yes, with two BIOS settings you switch on yourself: a supervisor password and Bottom Cover Tamper Detection. Once the bottom cover has been opened, the laptop stops before Windows loads and asks for that password. A new drive does not get round it, because the password is stored on the motherboard, not the disk. Guard checks that both settings are on and keeps the password encrypted in Rentablez so only an admin can reveal it. It never changes BIOS settings itself. This check is in Beta, is available on Windows ThinkPads only, and does not work on Macs or other brands. On every other laptop, hardware-swap detection still alerts you when a part changes.

Can I see where a rented laptop is?

Yes, approximately, and at no extra cost. Each time a laptop checks in, Rentablez works out the city from the internet connection it is using and puts it on a map, roughly to within 10 km, with a history going back up to 90 days. Nothing extra is installed and the customer is not asked for permission, because no data is read from the laptop itself. A VPN or a mobile hotspot can place it in the wrong city, so treat it as a lead, not proof. For street-level position, install the agent with Precise location: with the customer's permission, the laptop reports where it is from its own Wi-Fi or GPS every few hours, usually within 20 to 100 metres, and an admin can press Locate now. If the customer turns location off, you see it and can be alerted.

Can Guard send alerts on WhatsApp?

Yes. In the Guard app under Settings → Alerts you choose email, WhatsApp or both for each alert: hardware swap, format protection lost, precise location turned off, and laptop offline (after 1 hour to 7 days, 24 hours unless you change it). Alerts go to the WhatsApp number and email in your organisation details. Email is on unless you turn it off; WhatsApp is off until you turn it on, and each WhatsApp alert uses 1 credit.

Does Guard work on Linux?

Yes, in Beta, on Ubuntu 22.04+ and Debian 12+ laptops, desktops and servers. A locked Linux machine switches to the Rentablez lock screen and stays there through screen switching, logging out and restarts. Set a machine up as a server and Lock also blocks every connection except its link to Rentablez, so its websites, SSH and databases stop answering until you unlock; nothing is stopped or deleted. Linux machines also get a health monitor: free disk space, memory, temperature, load and failed system services every 5 minutes, with a 30-day history and an alert when a reading turns critical. The health monitor is Linux-only. Try it on one or two machines before rolling it out.

Can Guard stop a customer wiping the laptop?

On Lenovo ThinkPads and Dell Latitudes running Windows, OS format protection (Beta) closes the easy routes. The agent switches off Reset this PC and turns it off again within a day if someone re-enables it. Each day it also checks the BIOS settings you set yourself: a BIOS password, USB boot and the F12 boot menu off, and Secure Boot on. Each laptop shows as Protected, Partially protected or Unprotected, and you are alerted if a Protected laptop drops out. Guard never changes BIOS settings itself. A customer with Windows administrator rights can still run an installer from inside Windows, so give them a standard account.

Does Guard read files, screens or keystrokes?

No. Guard reports a hardware fingerprint, when the device last checked in, its hostname, the agent version and the approximate city it is connecting from; with Precise location switched on and the customer's permission, also its Wi-Fi/GPS position every few hours. On Linux, the health monitor adds disk, memory, temperature and load readings about the machine. It does not read documents, capture the screen, log keystrokes or track browsing.

Are the laptop inspections part of Guard?

No. Inspections are part of the Rentablez rental plans from Growth upward, not part of Guard pricing. They pair naturally with Guard because both run against the same asset record, which is why they are shown together here.

How does the licensing work?

Rentablez Guard is licensed per asset. One licence covers exactly one laptop and is held for as long as the agent is installed on it — it is not a floating seat and it cannot be shared between machines. Licences are bought in blocks of 100 at ₹1,000 per block per month (₹1,180 including 18% GST), and you top up a block whenever the inventory grows past your current allowance. Uninstall the agent and that licence returns to your pool the same day for the next machine. Pricing does not depend on how many staff you have or how many branches you run.

What does the free tier include?

Five licences are free for the life of the account, covering up to four Windows machines and one Mac. Every Guard feature is included on the free tier. Nothing is held back and it is not a trial. You buy your first block of 100 licences only when the fleet outgrows those five.
